Help me please with this Simplify. 5a-12a

1 answer:

4 0

It helps to imagine the variable a sort of as a unit. Like with 5 minus 12 lemons, it has no bearings on the addition/subtraction here.

Factor out a and subtract.

$5a-12a \\ (5-12)a \\ \boxed{-7a}$

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

using the rule of exponents

$a^{-m}$ = $\frac{1}{a^{m} }$

substitute x = - 3 into f(x)

f(- 3) = 4( $(2)^{-3}$ = 4 × $\frac{1}{2^{3} }$ = 4 × $\frac{1}{8}$ = $\frac{1}{2}$

In two hours Holden completed 3/4 of his race how long will it take Holden to complete the entire race?

vivado [14]

Answer:

$\frac{1}{4}$ = 50 Minutes

Whole Race Time : 2 Hour and 50 Minutes

Step-by-step explanation:

so 2 Hour = $\frac{3}{4}$ Race completed

we need to find what 1/4 Race = x Hours

so 200 divided by 4 because $\frac{3}{4}$ Race is done.

we need to find how long to finish the whole race also known as $\frac{4}{4}$ .

200 divided by 4 = 50

so Holden still need 50 Minutes to finish the race.
