Explain how to solve the equation and how to check the solution. 40 = 8y

answer is
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

Step-by-step explanation:

The scale factor on the map is 557.

What is scale factor?

When a shape is magnified and each side is multiplied by the same number, this is known as a scale factor. The scaling factor is this figure. Scale factors are used on maps to accurately depict distances between locations.

We have,

1 unit = 557 miles.

now, we have to find the scale factor,

i.e., the amount that must be multiplied by the map's unit of measurement to obtain the original distance between the two locations.

So, it means that the x unit = 557 x miles.

i.e. the scale factor = 557

Hence, The scale factor on the map is 557.

Elise is making 42 chocolate ice cream sundaes. The number of quarts of ice cream she needs is directly proportional to the number of people served. Suppose it takes 3 quarts of ice cream to serve 18 people. Which statements are correct for this situation?

A) Elise needs 7 quarts of ice cream
B) Elise needs 6 quarts of ice cream.
C) The constant of proportionality is 1 /6.
D) The constant of proportionality is 6/ 1.
E) The constant of proportionality is 1/ 8.

Answers

Answer:

A (Elise needs 7 quarts of ice cream)

Step-by-step explanation:

Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.

Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.

So 42 people divided by 6 equals 7 quarts.

Calculate the area of the triangle below.

Answers

Answer:

D- 52.5

Step-by-step explanation:

12ft + 3ft = 15ft

base= 15ft

height=7ft

area = 0.5 * b * h

area = 0.5 * 15 * 7

Answer:

52.5 ft^2

Step-by-step explanation:

7ft * 12ft = 84

84 / 2 = 42

7ft * 3ft = 21

21 = 2 = 10.5

42 + 10.5 = 52.5

5x3=15- the total measure of the circle top part

120+15= 135

ANSWER: 135

BRAINLIST??

Answer:

148cm²

Step-by-step explanation:

seriously why, just why? okay, hold on, we're gonna be here a while

Let's start with the triangles, they're all equal, and we already have their measurements and the formula for the area of a triangle is base x height ÷ 2, so all we have to do is plug:

5 x 8 = 40

40 ÷ 2 = 20

Now we have to multiply by 3 because there's 3 of these abominations:

20 x 3 = 60

So we put that on a back burner while we do the semicircle

So the formula for the area of a circle is pi x radius², so we have to find the radius. We know that each of the triangle bottoms is 5cm, so we just multiply by 3:

5 x 3 = 15

So the diameter of the semicircle is 15cm, now we divide that by two to find the radius:

15 ÷ 2 = 7.5

Now we just plug that into our formula (we're using 3.14 for pi)

7.5² = 56.25

3.14 x 56.25 = 176.625‬

Usually, we'd stop there, but it's only half of a circle, so:

176.625 ÷ 2 = 88.3125‬

So now we add both of our areas:

60 + 88.3125‬ =

148.3125‬

Normally, that would be the answer, but since we're supposed to be estimating, we round it to the nearest whole number:

148.3125 -> 148

So the area of the figure is 148cm²

if this is wrong, let me know so I can fix it

hope this helps:)

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the concentration of the mixture, hence:

(6 * 20%) + (4 * 5%) = x * (4 + 6)

1.2 + 0.2 = 10x
