So the rows are read from left to right, now down. This is probably a little late to be answering this, but see how the top row say 4 6 5? 4 quarters = 100, 6 dimes = 60, 5 nickels = 25, all together is 185. It's just asking you to fill in the blanks to make each row equal $1.87. So for pennies, you would put 2 to make 185+2 = 187 or $1.87. I was confused looking at this too. I was staring at it for an hour and I googled to see how other people answered this.

1 quarter = 25 cents
1 dime = 10 cents
1 nickel = 5 cents
1 penny = 1 cent

1) You need 2 pennies.
2) You need 7 pennies.
3) You need 9 dimes.
4) You need 2 quarters and 0 nickels.
5) You need 5 nickels.

Hope this helps =)

What is the missing length??
amid [387]

Answer

The missing length is 10

Step-by-step explanation:

Represent the missing length with x

The sides of the given shape are directly proportional.

Mathematically:

(15 + x) to (12 + 8) and x to 7

Represent as a ratio:

(15 + x) : (12 + 8) = x : 8

15 + x : 20= x : 8

Convert to fraction

\frac{15 + x}{20} = \frac{x}{8}

Cross Multiply:

(15 + x)*8 = 20 * x

120 + 8x = 20x

Collect Like Terms

20x - 8x = 120

12x = 120

Solve for x

x = \frac{120}{10}

x = 10

<em>The length of the missing side is 10</em>

8. Solve x/10 = –7. A. x = –0.7 B. x= –17 C. x = –70 D. x = 3
ANEK [815]
For this problem, I believe you would just have to plug in for x.

For example, -17 divided by 10 and so on.

The answer should be C, -70. -70 divided by 10 equals -7.
