Kyle drove x hours
Sally drove x + 7 hours
Added together they both drove 2x + 7 hours
2x +7 = 35 hours
Subtract 7 from both sides:
2x = 28
Divide both sides by 2:
x = 14
Kyle drove 14 hours
Sally drove 21 hours
Answer:
The answer is -32
Step-by-step explanation:
Multiply both sides by 8 to cancel 8 as the denominator and you have T = -32
4x - 5y = 15
put x=0, 4(0) - 5y = 15
-5y = 15
y = -3
coordinates (0,-3)
put y=0, 4x - 5(0) = 15
x = 15/4
coordinates (15/4,0)
put y=1, 4x - 5(1) =15
4x = 20
x = 5
coordinates (5,1)
Plot the three coordinates to obtain a straight line.
Note: You can also use other points rather from what i mentioned.

Answer:
Jess bought 403 pounds of each type of candy
Step-by-step explanation:
For this reason, though the PEA Mathematics Department promotes ... for me. It went over basic algebra and problem-solving techniques. ... priced at $4 per pound and candy priced at $3.50 per pound. Given that the bill came to. $20.75, figure out how many pounds of each type of candy Jess bought. 403.
Sorry if this is wrong and hope I helped! ^^
Answer:The answer is c
Step-by-step explanation:
Multiply both side is the equation by -1.
Sum the equations vertically to eliminate at least one variable
Divide both sides of the equation by 3
Substitute the given value of y into the equation 2x+3y=8
and then solve for x
