4x - 5y = 40
4x = 40 + 5y
x = 10 + 5/4y
The x intercept is 10.
The answer is -8°F. This is because it DROPPED 8 degrees, meaning it was 8°F MINUS 8°F which would equal 0°F. Hope that helps!
First you have multiply 6 by both 3x and 8
6*3x = 18x
6*8= 48
18x + 48 + 32 + 12x
now combine like terms
18x + 12x = 30x
48 + 32 = 80
so 30x + 80 is your answer
Answer:
1. y=-1/3x 2. y=2
Step-by-step explanation:
Step-by-step explanation:
1)X represents the time he spent in cardio.
Y represents the time he spent in weighted.
2)If you could put the options on the second one it would be better.
3)4x+y=210
3x+2y=195
y=210-4x
3x+2(210-4x)=195
3x+420-8x=195
5x=420-195
5x=225
x=45
y=30
Total time of one cardi and weighted = 75min= 5/4 h.
4)2x+4y=
90+120=210 total time of week three.
