8
Step-by-step explanation:
multiply 40 x 20 which =80
then put a point after the 8 then add a 0.
Your final answer should be 40% of $20 is $8.00
<span>Question 1
3y; y+y+y
3y = 3(2) = 6
y+y+y = 2+2+2 = 6
anwser: </span><span>They are both 6.
</span><span>Question 3
2z+3z
answer: </span><span>5z
part 2
</span><span>2z+3z
Evaluate the expression when z=7.
</span>2(7)+3(7) = 14 + 21 = 35
<span>Question 4
Consider the expressions 6x and 3(x+2).
</span><span>Evaluate each expression for x=2.
</span><span>
6x = 6(2) = 12
</span>3(x+2) = 3(2+2) = 3*4=12
<span>
answer:
</span><span>The expressions are not equivalent, but the answers are the same when x=2.
</span><span>Question 7
Select all the statements that are true.
_F__ 116b is equivalent to 16b.
_F__ 14b+13b is equivalent to 27b.
__F_ 13(b+7) is equivalent to 13b+73.
_T__ b+0.3+4b is equivalent to 5b+0.3.
</span><span>Question 8
Select all the statements that explain why 7x+2x and 4x+5x both equal 18 when x=2.
</span>7x+2x = 7(2) + 2(2) = 14 +4 =18 .......(9x)
and
4x+5x 4(2) +5(2) = 8+10 =18 .....(9x)<span>
Answer:
___ Both expressions simplify to 9x when like terms are combined.
___ The expressions are equivalent, because when you combine like terms in each, the result is the same.
</span><span>Question 10
Consider the expressions 2(x+2) and 2x+2.
</span><span>Evaluate each expression for x=4.
</span> 2(x+2) = 2(4+2) = 12 ..................(2x+4)
2x+2= 2(4)+2 = 10 ......................(2x+2)
answer:
<span>The expressions are not equivalent, and the answers are different when x=4.</span>
Answer:
12a. 22.5%
12b. 77.5%
13. $4000
Step-by-step explanation:
12.
a. 315/1400= 0.225 = 22.5%
b. 1400-315=1085 1885/1400= 0.775 = 77.5%
13.
5/100 will be equal to 200/4000 so the hair stylist made $4000 in sales.
also if im wrong sorry!!
