Use the distributive property.
9/10 (x + 8) = 18
9/10x + 7.2 = 18
9/10x + 7.2 - 7.2 = 18 - 7.2
9/10x = 10.8
9/10x / 9/10 = 10.8 / 9/10
x = 12
Answer:
False
Step-by-step explanation:
p(×)= -6x+1=-11
p(-2)= -6×-2+1=11
LHS=13
RHS=11
LHS≠RHS
Answer: false
Answer:
D
Step-by-step explanation:
(7 × 10-7) × 0.06
7 × 0.06 × 10^-7
0.42 × 10^-7
4.2 × 10^-8
Answer:
7/3 ft
Step-by-step explanation:
Given data
Lenght of fence= 7 miles
Amount completed= 2/3 of the total length
let us find the amount completed already = 2/3*7= 14/3 miles
Hence the length of fence remaining for completion is
=7- 14/3
=21-14/3
=7/3
Hence the amount in length undon is 7/3 ft
Let X be the number of hours
Brady drives 60 mph for X number of hours, which is written as 60x.
Mary drives 45 mph for x number of hours, which is written as 45x.
The equation to solve for the number of hours is:
60x + 45x = 1365
Simplify:
105x = 1365
Divide both sides by 105:
x = 1365 / 105
x = 13 hours.
