Answer:
x = 4
Step-by-step explanation:
Carry out the multiplication:
5(х – 10) = 30 — 15х => 5x - 50 = 30 - 15x
Combining the x terms, we get:
20x - 50 = 30
Combining the constants on the right side:
20x = 80
Dividing both sides by 20 yields x = 4 (second given answer)
Answer:what grade is this?
Step-by-step explanation:
$582.40 / 4 tires = $145.60
Answer: $145.60/tile
Step-by-step explanation:
for a perpendicular,
make x the subject.
8x=11-3y
x=11/8 +3/8
for a perpendicular, the gradient
x= -1/m
x= (-1/11/8) - (-1/3y/8)
x= 8/3y -8/11.
therefore the gradient (m) = 8/3y -8/11.
