Hi Strawberry12,

For problem 5, what you want to do is simplify the expression, cross multiply, then solve for e:

2(2/3)e = 1/18
(8/3)e = 1/18
8e/3 = 1/18
(8e x 18) = (3 x 1)
144e = 3
e = 3/144
e = 1/48

You would do the same thing for problem 6:

-1(2/7)m = 6
-(9/7)m = 6
-9m / 7 = 6 / 1
-9m = 7 x 6
-9m = 42
m = 42 / -9
m = -14/3

Hope this helps!

Good luck.

How does product (result) of (a-b)2 compare the product (a+b)
____ [38]
I'm assuming you mean (a-b)^2 : (a+b)^2

a^2 + b^2 cancel out leaving

-2ab versus +2ab

Therefore (a+b)^2 is +4ab greater.

A roll of ribbon was 12 meters long. Diego cut 9 pieces of ribbon that were 0.4 meters each to tie some presents. He then used t
dexar [7]

Answer: 8.4; 14.

Step-by-step explanation:

To find how much ribbon we used to tie presents, we need to multiply 9 and 0.4.

9 x 0.4 = 3.6.

Diego used 3.6 meters of yard to tie some presents. We can subtract that from 12 to find how much ribbon we have left.

12 - 3.6 = 8.4.

We have 8.4 meters of ribbon to make wreaths.

Now we have to find how many wreaths we can make wiht 8.4 meters of ribbon. We know that each wreath needs 0.6, so we should divide 8.4 by 0.6 to find how many wreaths we can make.

8.4 ÷ 0.6 = 14.

Therefore, we can make 14 wreaths with the 8.4 meters of leftover ribbon.

(Part A's answer is 8.4, and Part B's answer is 14)

I need help with these.
sattari [20]

Answer:

See below.

Step-by-step explanation:

1.

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x = 13

2.

3^2 + x^2 = [sqrt(10)]^2

9 + x^2 = 10

x^2 = 1

x = 1

3.

1^2 + x^2 = 4^2

1 + x^2 = 16

x^2 = 15

x = sqrt(15)

4.

[sqrt(27)]^2 + x^2 = 6^2

27 + x^2 = 36

x^2 = 9

x = 3

5.

15/5 = c/sqrt(29)

5c = 15 * sqrt(29)

c = 3sqrt(29)

6.

26/13 = x/12

2 = x/12

x = 24
