A student model relationship with equation y=4x
You can write this as an equation. P(price) = 4h(hours) +19. We know that P=35. If you plug it in, 35 = 4h +19. Subtract both sides by 19 to get 16 = 4h. Divide both sides by 4, and you get 4 = h, or the amount of hours, John rented the bike.
Answer:
15
Step-by-step explanation:
multiply both sides by 15
45x=675
Divide both sides by 45
x=15
Answer:
Step-by-step explanation:
<u>Put x = -3</u>
for any fraction a/b, the decimal format of it is just a ÷ b.
A)
is the number rational?
well, a rational number is one we can write as a ration or fraction, well clearly is a fraction so it is rational.
B)
can it be written as a repeating/recurring decimal? well, 9/20 is 0.45, so -9/20 is -0.45, no repeating decimal like 0.454545......... , just a plain vanilla -0.45, so nope.
C)
is it less than -0.4?
well, let's recall that for the negative side on the number line, the closer to 0, the larger the number, so then -1,000,000 is much smaller than -1, because -1 is closer to 0.
who is closer -0.4 or -0.45?
|--------------------- -0.45 -------- -0.40 ------------------- 0 --------------- 1 -------------------|
so, -0.45 is farther from 0, and therefore is smaller than -0.4, so yes.
