Step-by-step explanation:
A
![\sqrt[3]{27}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D)
= 3
Since 3 × 3 × 3 = 27
B
= ± 5
Since 5 × 5 = 25 and - 5 × - 5 = 25
C
= ± 9
Since 9 × 9 = 81 and - 9 × - 9 = 81
D
![\sqrt[3]{1}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B1%7D)
= 1
Since 1 × 1 × 1 = 1
Answer:
i think its 1/10 or 1 over 10
Step-by-step explanation:
Answer=875miles 17.5miles per gallon
350miles x miles
________=_________
20gallons 50gallons
cross multiply
20x=17500
divide both sides by 20
x=875
875 miles can be traveled with 50 gallons of gas.
To find gas milage, which is essentially miles per gallon, simply divide the number of miles by the number of gallons
350miles 20gallons
350/20=17.5 miles per gallon
Answer:
7
Step-by-step explanation:
We know that x^a / x^b = x^ (a-b)
b^4 / b^ -3 = b^(4 - -3) = b^ (4+3) = b^7
The exponent for b is 7
Answer:
x = 12
y = 4
Step-by-step explanation:
x + y = 16
x - y = 8
y + 8 = x
Replace x with y + 8 in the new equation
8 + 2y = 16 ----> we can minus 8 on both sides
2y = 8 -----> divide both sides by 2
y = 4
Now for the x value
x + 4 = 16 ----> minus 4 on both sides
x = 12
