Answer:
1) 8.5x10^8
2) 5.3x10^-3
3) 9.95x10^12
Step-by-step explanation:
Since they have the same exponents, you just add or subtract and leave the rest the same.
1) 8.5x10^8
2) 5.3x10^-3
3) 9.95x10^12
Option D
Using the distributive property, -7(8x – 3) + x = -55x + 21
<em><u>Solution:</u></em>
Given that we have to use distributive property to simplify the given expression
Given expression is:
-7(8x – 3) + x
Let us first understand about distributive property
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
<em><u>The distributive property is represented as:</u></em>
a(b + c) = ab + ac
Apply this property in given expression for -7(8x - 3)

Apply the above result in given expression

Combine the like terms. Add -56x and x

Thus the given expression is simplified. Option D is correct
It will cost 12 dollars because you divide .75 by 1.5 to find the price per unit then you multiply by 6
Answer:
you are multiplying by 7
Step-by-step explanation:
so like 3 x 7 = 21
4 x 7 = 28
6 x 7 = 42
9 x 7 = 63
10 x 7 = 70
