3t+4t=17.5 what does it equal

Hello!

[tex]\large\boxed{5, -8}[/tex]

5x + 2y = 9

4x - 3y = 44

We can eliminate y by multiplying both expressions in order to have the y coefficients equal.

The LCM (least common multiple) of 2 and 3 is 6, so we can multiply each accordingly:

3(5x + 2y = 9)

2(4x - 3y = 44)

Distribute:

15x + 6y = 27

8x - 6y = 88

Cancel using addition:

15x + 6y = 27

8x - 6y = 88

------------------

23x = 115

Divide:

x = 5.

Plug in this value of x into an equation to solve for y:

5(5) + 2y = 9

25 + 2y = 9

2y = -16

y = -8

The solution of the system is:

(5, -8).

Answer:

50 grams per egg is the constant of proportionality.

Step-by-step explanation:

A constant of proportionality is when two variables have a constant ratio in their relationship, typically exhibiting a linear relationship.

The equation for the constant of proportionality can be written as y = kx, where k is your quantitative constant.

Let's plug in these values into our equation:

Y = 300 (we are given that)

X = 6 (we are given that)

K = ? (we are not given that)

So now, we have 300 = k(6).

We now want to solve for k.

To isolate the k variable, we must divide both sides of the equation by 6

This gives us: [tex]\frac{300}{6} = k[/tex]

300 divided by 6 = 50.

Therefore, our constant of proportionality is 50, meaning that the weight of each additional egg is 50 grams. In context, this means that if one egg were to be added, the weight of the total eggs would increase by 50 grams per egg. Hope this helped!

Games won divided by games played.

We must convert 60/75 to a decimal.

So, 60 ÷ 75 = 0.80.

Now convert 0.80 to a percent.

So, 0.80 becomes 80%.

Done.

Answer:

c=14•366

14•4 to the nearest tenth

Step-by-step explanation:

using Pythagoras theorem

c^2=a^2+b^2

c^2=7•9^2+12^2

c^2=62•41+144

c^2=206•41

take the square roots of both sides

c=14•3669

14•4 to the nearest tenth

Answer:

Area of the triangle is 10 square units

Step-by-step explanation:

Recall that the formula for the area of a triangle is: "base x height / 2", and  in this case, we can consider the triangle's base as the segment that joins the vertices (5, 4) and (5, 8) which gives a segment length of 4 units. The height of the triangle is then the distance between the third vertex (0,7) and the base, which is exactly 5 units. Then the area becomes:

Area = 4 x 5 / 2 = 10 square units.

Answer: D, h = -2

Step-by-step explanation:

This is a horizontal shift, the general case is:

If you have a function f(x), the function g(x) = f(x - A) wil move the graph of f(x) A units to the right (Where A is a positive number).

And h(x) = f(x + A) will move the graph A units to the left.

in this case, we have:

g(x) = f(x - h) = 1/(x - h)

Then to find the value of h, we need to count how many units the graph of f(x) has been moved.

We can see that the asympthotes are at x = -2, and those would be at x = 0 for f(x) = 1/x.

Then we have a horizontal shift of 2 units to the left.

This means that

g(x) = f(x + 2)

Then we must have that h = -2.

The correct option is D

-2

5x +7/2 = 3x/2 -14

10x+7/2 = 3x-28/2

2(10x+7) = 2(3x-28)

20x -6x = -56 - (14)

14x = -70

x = -70/14

x = -5

14 Semesters Per Credit

Step-by-step explanation:

The rate at which she is earning credits is 14 credits per semester.

What is an expression?

Expression in mathematic is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Here in this question it is given that a college student had 15 credits already when she started her college and at the end of 4 semesters she had 71 credits which means she earned in total 71 - 15 = 56 credits. And the credits she earned is divided equally into all the 4 semesters, Now the rate at which she is earning credits is :

total credits earned by her divided by number of semesters = 56/4 = 14 credits.

Therefore, the rate at which she is earning credits is 14 credits per semester.

I dont know part A but I did sum like this in class today

The constant of temperature change if, the temperature changed at a constant rate between 12 P.M. (noon) and 6:30 P.M. is  -0.8.

One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components.

Given:

The temperature changed at a constant rate between 12 P.M. (noon) and 6:30 P.M.,

Change the 6h and 30 minutes to decimal as shown below,

6 + 30 / 60

6.5 hours

Divide the temperature change -5.2 by time as shown below,

The temperature change = -5.2 / 6.5

The temperature change = -0.8

Answer:

(2.5, -3.25)

Step-by-step explanation:

In relictions, only one value in the coordinate changes, either the x or y value depending on the type of reflection

First, reflect the coordinate over the x-axis.

Reflections across the x-axis is basically folding the graph across the x-axis. If you fold the graph across the x-axis, you notice that only the y-value is changing to be the opposite sign.

Basically in a reflection of the x-axis, the coordinates (x, y) change to (x, -y)

Therefore, (-2.5, -(3.25)) turns into (-2.5, -3.25)

Next, reflect the coordinate (-2.5, -3.25) across the y-axis. Similarly as above, reflections across the y-axis is like folding the graph on its y-axis. If you do so, you notice that only the x-value changes while the y-values stays the same.

Therefore (x,y) turns into (-x, y)

So, (-2.5, -3.25) = (-(-2.5), -3.25) = (2.5, -3.25)

Answer:

[tex](2.5 , -3.25)[/tex]

When you do a reflection, the negative values turn positive and the positive values turn negative.

Currently in the graph, the ordered pair is (-2.5, 3.25).

So, we will flip the two around.

Now, we will put them into an ordered pair again.

Our new ordered pair will be (2.5, -3.25)

Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

[tex]x-20\%\text{ of }x=7000[/tex]

[tex]x-\dfrac{20}{100}x=7000[/tex]

[tex]x-0.2x=7000[/tex]

[tex]0.8x=7000[/tex]

Divide both sides by 0.8.

[tex]x=\dfrac{7000}{0.8}[/tex]

[tex]x=8750[/tex]

So, the cost of the machine is 8750/-.

Now,

[tex]\text{Gross Loss}=\text{Cost}-\text{Selling price}[/tex]

[tex]\text{Gross Loss}=8750-7000[/tex]

[tex]\text{Gross Loss}=1750[/tex]

Therefore, the gross loss is 1750/-.

the answer is 78.12

Step-by-step explanation:

Answer: 78.12

Step-by-step explanation:

8.4 x 9.3 =

4 x 3 = 12, bring the ones to the tens place

8 x 3 = 24 + 1 = 25

252.

Add a 0 to the ones place.

9 x  4 = 36, add a 6 to the tens place, bring the tens to the hundreds place

9 x 8 = 72 + 3 = 75.

7560 + 252 = 7812.

Since there are two numbers behind the decimal, we put the decimal between the 8 and the 1.

8.4 x 9.3 = 78.12
