What Is The Value Of X

Answers

Answer 1
2x + 10 + 5x + 10 + 90 = 180 (add up all the angles and since it’s a triangle it must equal 180)
7x = 70 (add the like terms)
x = 10 (divide both sides by 7)
Answer 2
90+(2x+10)+(5x+10)= 180
110+7x=180
7x=70
x=10

Answers

ANSWER: 864
First you do 12 times 12 that is 144 then you divide it by 2 because it is a triangle
Then 12 times 44 and get 500 something and divide it by 2 because it is also a triangle and get 264 then you subtract 56 and 12 and get 44 and times that by 12 and get 528 then you add up all the numbers and should get 864

Answer:

Volume of cube-shaped box = 91.125 cubic inches

Ex:

The formula is  V = s^3, where, s is the side length and V is the volume. Thus plugging in, we get:

[tex]V= s^{3}[/tex]

[tex]V= (4 \frac{1}{2} )^{3} \\[/tex]

[tex]V= (4.5)^{3}[/tex]

[tex]V=91.125[/tex]

(b) Volume for this one is 729 cubic inches

Since the volume of a single box o(cube-shape) is 91.125 cu. in., and the volume of larger box is 729, we can divide 729 by 91.125 to find how many of them would fit the large box. So 8.

Answers

Answer:

the 4th one

Step-by-step explanation:

The data points are in alignment with the line, showing it as a linear graph, even though the data points are scattered.

sorry if Im wrong

the answer is c because the line of fit has to have around the same amount of points in each side so with c (the third one) there are 6 points on top and 6 points on the bottom therefore that’s the answer. But there doesn’t have to be an exact amount in the top or bottom just around the same so a wouldn’t work since there’s so much on the top while a little on the bottom.

Jaden’s teacher had 4 boxes of pens that each contained y pens. She took 6 pens out of one of the boxes and told her 17 students to divide the remaining pens equally among themselves. Which expression shows the number of pens each student got?

Answers

Answer:

[tex]\frac{4y - 6}{17}[/tex]

Step-by-step explanation:

There are 4 boxes containing y number of pens. This means that in 4 boxes there are y pens so we multiply 4 and y. The teacher then takes 6 pens out so you minus the amount of pens from the 4y leaving 4y - 6.The teacher then asks the students to share the pens out between 17 of them equally. To do this you must divide by 17 to get an equal number of pens for each student. This means the correct expression is [tex]\frac{4y - 6}{17}[/tex]
This answer is right

What scale factor was used to produce figure 1 from figure 2?

two triangles labeled figure 1 and figure 2, where figure 1 has legs that are 2 units long and figure 2 has legs that are 6 units long

one sixth
one third
3
6

Answers

Answer:

I believe it's 6, I'm super sorry if I'm wrong.

Step-by-step explanation:

I really hope this helps you!

To find the scale factor used to produce figure 1 from figure 2, we can divide the length of a leg in figure 1 by the length of the corresponding leg in figure 2.

Length of leg in figure 1 = 2 units
Length of leg in figure 2 = 6 units

Scale factor = Length of leg in figure 1 / Length of leg in figure 2 = 2/6 = 1/3

Therefore, the scale factor used to produce figure 1 from figure 2 is 1/3.

A checking account has a balance of $350. A customer makes two withdrawals, one $50 more than the other. Then he makes a deposit of $75. write an expression for the new balance using as few terms as possible.

Answers

Answer:

375-2x

Step-by-step explanation:

Bal =350

Let 1st withdrawal be x

2nd withdrawal will be x+50

Deposited 75

New Balance =350 - (x+x+50) +75

=350-2x-50+75

=375-2x

Answer:

Step-by-step explanation:

Initial account balance = A

= $350

Two withdrawals:

Second withdrawal, y = x + 50

Deposit = p

= $75

New balance = n

n = A - (y + x) + p

n = A - (x + 50 + x) + p

Inputting values,

n = 350 - (2x + 50) + 75

Simplifying further,

Expression:

n = 375 - 2x

Where x is the initial amount withdrawn

PLSSS help, i will give brainliest!!!

Answers

Answer:

Answer A

Step-by-step explanation:

180° = 84° + (x + 46)°

(x + 46)°= 180° - 84°

x = 180° - 84° - 46° = 50°

(2x + 31)° = 131°

which means the next angle to it equals 180° - 131° = 49°

and as we know if we add up a triangle's angles it equals 180°

so the last unknown one is 180° - 84° - 49° = 47°

then a° = 180° - 47° = 133°

Answer:

A) 133°

Step-by-step explanation:

First, we solve for x.

84+x+46=180

130+x=180

x=50

Now, we plug that into 2x+31

2(50)+31=131

Then, 180-131 gives us an interior angle of 49.

Now we have two interior angles and can solve for the third.

180-84-49=47

Then we can find a by subtracting that from 180

180-47=133

Earl made a 1/2 pan of brownies using 2/3 cup of sugar how much. sugar will it take for a whole pan of brownies

Answers

If Earl made a 1/2 pan of brownies using 2/3 cup of sugar, we can use a proportion to find out how much sugar he will need for a whole pan of brownies.

Let's call the amount of sugar needed for a whole pan of brownies "x". Since a whole pan is twice the size of a half pan, we can set up the proportion:

1/2 pan / 2/3 cup sugar = 1 whole pan / x cups sugar

To solve for x, we can cross-multiply and simplify:

1/2 pan * x cups sugar = 2/3 cup sugar * 1 whole pan
x/2 = 2/3
x = (2/3) * 2
x = 4/3

Therefore, Earl will need 4/3 cups of sugar for a whole pan of brownies. This can be simplified to 1 and 1/3 cups of sugar

Answer:

4/3 Cups of Sugar

Falcons; they have a larger mean value of about 22.3 inches

Seahawks; they have a larger median value of 23 inches

Falcons; they have a larger median value of 22.5 inches

Answers

Answer:

The team that has the largest overall size hat for their players is the Seahawks; they have a larger mean value of about 23 inches. The correct option is C.

Step-by-step explanation:

What is the mean and median?

The two most frequently used measures of center are mean and median. When we compare the mean numbers for the Falcons and Seahawks, we can see that the Falcons have a mean of roughly 22 inches and the Seahawks have a mean of roughly 23 inches.

Nevertheless, when the data is skewed or contains outliers, the mean may not be the best approximation of the center because the mean can be altered by extreme values or outliers. Thus, we also need to compare the median values. The median is the midway value in the ordered set of data.

Thus, the correct option is C, Seahawks; they have a larger mean value of about 23 inches.

Choose the inequality that represents the following graph.

Answers

Answer:

B.

Step-by-step explanation:

Because the circle or dot on the number line is filled (isn't hollow), it means that it include the number 4.

Also, since the line is going towards the right (becoming less and less), the number (x) must be -4 or less.

Answer:

B. [tex]x\leq -4[/tex]

Step-by-step explanation:

When you graph the inequality, you use the following;

If the equation has a [tex]\leq[/tex] sign, you use a closed circle and it goes left, since it is less than.

When you graph, you look at what sign the equation has, and you look at what number the variable (x) is less than or greater than and put the dot on that number. In this case, it is [tex]\leq[/tex] -4, so the dot will be on -4.

When you put it all together;

Since it is [tex]\leq[/tex], there will be a closed circle.

The equation is x [tex]\leq[/tex] -4, so the dot will go on the -4 and go left.

All of the characteristics of the equation match the graph, therefore, it is B. x [tex]\leq[/tex] -4.

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
