7). C
8). 60
n = 5(10) + 10
n = 50 + 10
n = 60
9). 17
f(x) = -2x + 7 plug the -5 in for x
f(x) = -2(-5) + 7
= 10 + 7
= 17
10).
3/4÷1/8 is the same as 3/4×8/1.
3×8=24
4×1=4
That becomes 24/4 which simplifies to 6. Your answer is 6.
Answer:
percent error=6%
Step-by-step explanation:
Step one:
given data
Patty counted 250
The actual amount of chocolate chips on the tray were 265
Required
The percent error
Step two:
The formula is
percent error= actual-expected/expected*100

percent error=15/250*100
percent error=0.06*100
percent error=6%
Answer:
-7.17
Step-by-step explanation:

Remember
∛(xy)=(∛x)(∛y)
3rd power
factor inside and group
384=2*2*2*2*2*2*2*3=2^3*2^3*2*3=2^3*2^3*6
∛384=(∛2^3)(∛2^3)(∛6)=(2)(2)(∛6)=4∛6
