You first round 289 and get 290 then multiply it by 7

Id reccomend rounding the answer to a easier number, which in this case would show to be 300. Then multiply that by 7, but to make it even easier, take off those Zeros, multiply the 7 by 3, which would be 21, then add the zeros back and you would get a answer close enough to what the question is asking you.

alukav5142 [94]

Answer:

The answer is 8 quarters, 16 nickles, and 32 dimes

Step-by-step explanation:

First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.)
Then we slowly start to solve: 10/4d + 10d + 25/4d = 600
10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d)
75d= 600 x 4
d=600 x 4/75 (same here put everything over 75)
d=32
So then n= 2 x 32/4 = 16
Then n would be equal to : 1/4d= 1/4 x 32 = 8
So your answer would be 8 quarters, 16 nickles, and 32 dimes.

Hope this helped :)

Factor each expression. (9) 5a - 25 (10) 28 - 7x (11) 12z + 28 - 7z - 3

Nimfa-mama [501]

Answer:

Step-by-step explanation:

Look for the GCF and then divide every term by the GCF to see what remains

(9) 5a - 25 ( GCF is 5 so take out 5 and divide every term by 5)

5(a-5)

(10) 28 - 7x ( GCF is 7 so take out 7 and divide every term by 7)

7(4-x)

(11) 12z + 28 - 7z - 3= (combine terms) =

5x+25( GCF is 5 so take out 5 and divide every term by 5)

5(x+5)
