Answer:
56x-38
Step-by-step explanation:
2(8x+9)-8(7-5x)
16x+18
-8(7-5x)
-56+40x
16x+18-56+40x
Add all like terms
56x-38
There are 5280 feet in one mile.
If you have one and two-thirds of a mile, you can divide 5280 by 3, multiply it by 2, and then add it to 5280.
This will give you an answer of 8800 feet in 1 2/3 miles
Answer:
1/64x^12
Step-by-step explanation:
Answer:
1 solution
Step-by-step explanation:
y = 1/2x + 4
x + 2y = -8
Solve the second equation for y.
2y = -x - 8
y = -1/2x - 4
The two equations in slope-intercept form are:
y = 1/2x + 4
y = -1/2x - 4
The system consists of two lines with different slopes, so they intercept at a single point which is the solution.
