<h3>Answers:</h3><h3>First box = 57.14</h3><h3>Second box = 80</h3>

=============================================

Explanation:

If you save 65%, then you pay the remaining 35%

0.35x is the final price when x is the original price

0.35x = 20 solves to x = 57.14 approximately after dividing both sides by 0.35

57.14 goes in the first box

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

This must mean 80 goes in the other box.

Here's the steps on how to get 80

If you save 75% then you pay the remaining 25%

0.25x = 20

x = 20/0.25

x = 80

80 goes in the second box

If you turn 9 1/3 in to a decimal and 3 1/2 in a decimal also 

9 1/3 = 9.3 and 3 1/2 =3.5 
9.3+3.5 =12.8 
12.8=12 4/5

Amy looks up to the 8-foot basketball hoop as shown. If the vertical distance from the ground to Amy’s eyes is 5.9 feet, what is
Igoryamba
The angle of elevation<span> of an object as seen by an observer is the </span>angle<span> between the horizontal and the line from the object to the observer's eye (the line of sight). since you did give the horizontal distance between amy and the hoop, so let us represent it as x.
so the angle of elevation = tan^-1 ( (8 - 5.9) / x)
angle elevation = tan^-1 ( 2.1 / x )</span>

Solve the system of equations
FromTheMoon [43]

Answer:

x=18

Step-by-step explanation:

add 2y to both sides 5x=2y+88

subtract 88 from both sides 2y=5x-88

substitute 2y in the second equation for 5x-88

3x+10x-176=58

add like terms 13x-176=58

add 176 both sides

13x=234

x=18

Factor the expression using the GCF. A. 2(4a + 8c) B. 4(2a + 4c) C. 8(a + 2c) D. 16( 12 a + c) Not multiple choice
dimulka [17.4K]

Note: The expression is missing. Consider the expression is 8a+16c.

Given:

The expression is

8a+16c

To find:

Factor form of the given expression by using GCF.

Solution:

We have,

8a+16c

Factors of each term:

8a=2\times 2\times 2\times a

16c=2\times 2\times 2\times 2\times c

The common factors are 2, 2 and 2. So,

GCF(8a+16c)=2\times 2\times 2

GCF(8a+16c)=8

Taking out the greater common factor (GCF) in the given expression, we get

8a+16c=8(a+2c)

Therefore, the required expression is 8(a+2c) and the correct option is C.

If x=4 cm find the area of this triangle ​
My name is Ann [436]

Answer:

The answer to your question is 4.

Step-by-step explanation:

You take

7 and times it by 4

than you take 8 and times it by 4

Now you take both numbers

28 times by 32 to equal 896

Finally you divide your number by 2. To equal 448.

Here is the formula

Area= Base * Height / 2

:) Hope this helps
