Group the terms with variables on one side of the equal sign, and simplify.
8t −15 = 32t

Answers

Answer:

t = -5/8

Step-by-step explanation:

1.) Add 15 to each side canceling it out on the left

8t - 15 = 32t

    +15    +15

2.) Subtract 32 from each side canceling it on the right

8t = 32t +15

-32t  -32t

3.) Divide each side by 24 to get the variable

-24t = 15

-24t/-24t = 15/-24t

4.) Simplify by 3

5/-8

t = -5/8

Subtract 8t from 8t and then do 32t- 8t. The new equation is -15=24t. That is the new equation simplified. But the answer would be t=15/24, but you can simplify that which would be t=5/8

Answers

The concentration of the mixture made by mixing 6 fl. oz. of a 20% alcohol solution and 4 fl. oz. of a 5% alcohol solutions is 14%

What is an equation?

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

x = 0.14 = 14%

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.

Step-by-step explanation:

Action- 28%
Comedy- 12%
Drama- 16%
Thriller- 44%

Step by step explanation:
Add up all of the numbers, so here it would be 70+30+40+110 and you would get 250 so then you divide each number by 250. 70 divided by 250 is .28 so u make that into a percentage which is 28%, 30 divided by 250 is .12 so 12%, 40 divided by 250 is .16 so 16%, and lastly, 110 divided by 250 is .44 so 44%

which expression is equivalent to 3y - 8 - 7y + 9


-3y

-10y + 1

-9y

-4y + 1

Answers

The second one.

Because 3y-7y = -10y and -8+9 = 1
-10y + 1
-10y + 1 because when you combine like terms 3y minus -7y because of the subtraction symbol in front so that equals -10y then -8 + 9 equals 1 so it’s -10y + 1

Help)Area of Composite Figures(Help

Answer:

F) = 79.27cm

G) = 50.8cm

Step-by-step explanation:

For F, add the area of the rectangle (8*5 = 40) to the area of the half circle ((pi * 5^2)/2 = 39.27) to get the total (79.27)

For G, add the area of the square (5.5*5.5 = 30.25) to the area of the trapezoid (3 * (8.2+5.5)/2 = 20.55) to get the total (50.8)

Multiply 5 x 8= 40 -the total of one triangle

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
