Answer 1

Answer:

B

C

E

Step-by-step explanation:

5+2=7

3x5=15

5-5=0

Answer 2

Answer:

A.  20 - x = 5     X = 15

B.  x + 2 = 7       X = 5

C.  3x = 15         X = 5

D.  5x = 15         X = 3

E.   x - 5 = 0       X = 5

Step-by-step explanation:

For A

Steps

20 - x = 5

subtract 20 from both sides.

20 - x - 20 = 5 - 20

Simplify

-x = -15

Divide both sides by negitive 1

-x/-1 = (-15)/ -1

Simplify

x = 15

For B

Steps

x + 2 = 7

subtract 2 from both sides.

x + 2 - 2 = 7 - 2

Simplify

x = 5

For C

Steps

3x = 15

Divide both sides by 3

3x/3 = 15/3

Simplify

x = 5

For D

Steps

5x = 15

Divide both sides by 5

5x/5 = 15/5

Simplify

X = 3

For E

Steps

x - 5 = 0

Add 5 to both sides

x - 5 + 5 = 0 + 5

Simplify

X = 5

That was A lot of math lol but I hope that helped

Kori has 12 strawberries, 3 pineapples, and 4 kiwis. What is the ratio of strawberries to total fruit?
HELP!

Answers

Answer:

12:19

Step-by-step explanation:

To create a ratio, we compare a portion to a whole. In this case our portion is 12 strawberries. Our whole is the total fruit, so let's add up each fruit to find the total.

12 + 3 + 4 = 19

Now we have our portion (12) and our total (19).

Let's create a ratio.

12:19

This ratio cannot be simplified further, so that is your answer.

Hope this helps!

12:19 12 is for the strawberries then if you add up all he fruit you have 19

In A ABC, AB = CA and mC = 27°. Find mZB.

Answers

Answer:

since AB and CA is equal, it means that this triangle is an isosceles triangle and that it means that whatever the angle C is, b is also that angle.

so if she is 27 degrees then b is 27° as well

but to find a, you must subtract 180 with the sum of angle b and C

so..

180-(27+27)

180-54

therefore a would be 126°

The store is selling lemons at $0.41 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy
enough lemons to make three 9-inch lemon pies, each requiring half a cup of lemon juice?

Answers

Answer: It costs about 7.32 to buy enough lemons.

Step-by-step explanation:

Each lemon yields 2 tablespoons, which is equal to one fluid ounce.  

8 fluid ounces = one cup, 4 fluid ounces = half a cup

Four lemons will provide juice for one pie.

Cost of one pie = 4  0.61 =  2.44

Cost of three pies = 2.44   3 =  7.32
