Answer:
(0, 3)
Step-by-step explanation:
Let's first eliminate x. To do this, multiply all three terms of the first equation by 5:
-5x + 20y = 60
5x - 2y = -6
----------------------
18y = 54, so that y = 3.
Substituting 3 for y in the first equation yields:
-x + 4(3) = 12, or -x = 0. Thus, x = 0, and the solution is
(0, 3)

Step-by-step explanation:
(10 − 6)3 ∙ 4(2) + (10 + 2)2, (8 − 6)5 ∙ 2(-4) + (6 − 8)0,
(5-2)-5 x 3(2) + (5+2)0
Answer:
120, -80, -90
Step-by-step explanation:
Use order of operations to solve each:
(10 − 6)3 ∙ 4(2) + (10 + 2)2
(4)3 x 4(2) + (12)2
12 x 8 + 24
96 + 24 = 120
(8 − 6)5 ∙ 2(-4) + (6 − 8)0
(2)5 x (-8) + (-2)0
10 x (-8) + 0 = -80
(5-2)-5 x 3(2) + (5+2)0
(3)-5 x 6 + (7)0
-15 x 6 + 0 = -90
Maria bought an SUV for 21,000 dollars. Nancy bought a sedan for 2/3 as much. How much less did Nancy spend on her sedan?
Answer:
7000
Step-by-step explanation:
21,000*(2/3)=14000
21,000-14,000=7000
Answer:
7,000 dollars
Step-by-step explanation:
21,000 divided by 3 is 7,000 = 1/3
So 2/3 = 7,000 x 2 = 14,000
To find how much less Nancy spent on her sedan you do 21,000 - 14,000 = 7,000
What is the length of the missing leg
Answer:
12
Step-by-step explanation:
Using the pythagorean theorem, we know that a^2+ b^2=c^2
In our case, we know b, which is 5 and c which is 13.
If we plug that into the equation, we get a^2+ 5^2 = 13^2
Next, we simplify the equation. a^2 + 25 = 169
Then we subtract 25 from 169. 169 - 25 = 144.
Lastly, we do the square root of 144 and we get 12 which is the missing side.
Answer: 12 miles
Step-by-step explanation:
Use Pythagorean Theorem to find the missing side.
a^2 + 5^2 = 13^2
a^2 + 25 = 169
subtract 25 from both sides
a^2 = 144
take the square root of both sides
a = 12

To apply frosting to a cake, a baker twists a plastic bag containing the frosting into a cone shape with a diameter of 4.2 inches and a length of 6 inches. How many cubic inches of frosting is in the bag? Use 3.14 for pi.
Answer:27.7
Step-by-step explanation:
the formula for a cone is V=1/3πr*2h
it is 1/3 because a cone is one-third of a sphere.
you then put the information from the text in the formula and you get this
V=1/3x 3.14 (pi) x 2.1 to the power of 2 (radius is half of a diameter)x 6 (height)
then you get the answer 27.6948
round to the nearest 10th and you get
A. 27.7
Also, I took the test.
There are 27.77 in³ of frosting is in the bag.
What is volume?The amount of space, measured in cubic units, that an object or substance occupies.
Given that, To apply frosting to a cake, a baker twists a plastic bag containing the frosting into a cone shape with a diameter of 4.2 inches and a length of 6 inches.
Volume of cone = ¹/₃πr²h
r = 4.2/2 = 2.1 in
h = 6 in
Volume = ¹/₃x2.1x2.1x6
= 27.77
Hence, the volume of the cone is 27.77 in³

How is the distributive property used when multiplying two binomials
Answer:
Step-by-step explanation:
When multiplying a binomial times a binomial, each term of the first binomial must be multiplied by each term of the second binomial. Like terms are then combined.
When multiplying two binomials, four multiplications must take place. These multiplications can occur in any order, as long as each of the first two terms is multiplied by each of the second two terms.
There are numerous ways to set up the multiplication of two binomials. The two basic formats, horizontal line-up and vertical line-up, are similar to what we saw in adding and subtracting polynomials. Let's investigate the simple product (x + 2)(x + 4) with a variety of set-ups. Start with the first term of the first binomial (the blue x).
• Distribute (multiply) this term times EACH of the terms in the second binomial (x + 4).
• Then take the second term in the first binomial (including its sign: +2) and distribute (multiply) this term times EACH of the terms in the second binomial (x + 4).
• Add the results, combining like terms when needed.
• This method will work with all polynomials, not just binomials times binomials.
Answer:
Distributive.

Suppose that y varies inversely with x. Given x=-3 when y=-105. Find y when x=15
Answer:
21
Step-by-step explanation:
It is given that y varies inversely with x.
[tex]y\propto \dfrac{1}{x}[/tex]
[tex]y=\dfrac{k}{x}[/tex] ...(i)
where, k is constant of proportionality.
It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.
[tex]-105=\dfrac{k}{-3}[/tex]
[tex]-105\times (-3)=k[/tex]
[tex]315=k[/tex]
Now,
[tex]y=\dfrac{315}{x}[/tex]
Substitute x=15 in the above equation.
[tex]y=\dfrac{315}{15}[/tex]
[tex]y=21[/tex]
Therefore, the value of y is 21 when x=15.

Answer:
x = 25.6
Step-by-step explanation:
1. Both angles towards the bottom equal 48 degrees, so the angle on the left (already shown) and across on the right equal 48. Add/multiply both of them
48 * 2 = 96
Now, like triangles, figures with 4 sides add up to a certain number of degree. Four sided figures or quadrilaterals (the ”fancy” math word for it) add up to 360 degrees.
2. Adding up to 360 degrees means that all four angles have to be evenly split, you already know that the corners are 48 degrees, the bottom corners, you don’t know yet, therefore, we subtract 360 by 96 and divide the difference.
360 - 96 = 264
264/2 = 132
3. From the explanation above, you now know that the bottom corners will equal 132 degrees, therefore you will set the equation to be equal to 132 degrees.
5x + 8 = 132
5x = 128
x = 25.6
The answer is x = 25.6, I hope this explained everything, there are some theorems which make remembering these steps a lot easier, and alternative approaches you could have taken, but this is my approach.

The number of visitors to Disney’s Epcot center food court is 1,940 today. This is 400% of the number
of visitors on the first day the food court was open. How many visitors did the food court have on the first
day? pls show work
Answer:
The Disney Epcot Center food court had 485 visitors on the first day
Step-by-step explanation:
Let's answer the question correctly, this way:
Number of visitors today = 1,940 and 400% of the visitors on the first day
How many visitors did they have on the first day?
Let's use the Rule of Three Simple, this way:
x = Number of visitors to the center food court on the first day
Number of visitors Percentage
1,940 400%
x 100%
400 * x = 1,940 * 100
x = 194,000/400
x = 1,940/4 = 485
The center food court had 485 visitors on the first day

The total surface area of the cube is 96 square centimeters.
We have,
Given that each side of the cube measures 4 cm, the formula to calculate the surface area is:
Surface Area = 6 * (side length)²
Substituting the value of the side length,
Surface Area = 6 * (4 cm)²
Surface Area = 6 * 16 cm²
Surface Area = 96 cm²
Therefore,
The total surface area of the cube is 96 square centimeters.
