How do you answer this equation?<br> 5a - 12 = 48

Add 12 to both sides resulting in 5a = 60 and then divide both sides by 5 which results in a = 12 so your answer will be a = 12

Translate the sentence into an inequality.
grigory [225]

Answer:

8b + 27 ≤ - 29

Step-by-step explanation:

Sum of a number can be written as x or in this case as b because it is an unknown number.

b is multipled by 8 so 8b

"and 27" indicates an addition so therefore, 8b + 27

"at most -29" This is a little bit tricky but ultimately it means 8b + 27 cannot be more than -29. Therefore, it must be lesser than.

However there is a line underneath that lesser than sign meaning lesser than or equal to. I believe that "at most" indicates equal to.

Other than the lesser than or equal to sign I'm unsure about, this inequality should be correct.

What conclusions can be drawn about finding the quotient in scientific notation? Check all that apply. Start Fraction (9.6 times
bija089 [108]

Answer:

B.The exponent of the solution is –12, the difference of the original exponents.

C.The coefficient of the solution must be greater than or equal to one but less than 10.

D.The quotient is 3.0 × 10^{-12}

Step-by-step explanation:

We are finding the quotient of the expression below in scientific notation

\dfrac{9.6X10^{-8}}{3.2X10^4} \\=\dfrac{9.6}{3.2}X10^{-8-4}\\ =3 X 10^{-12}

The following conclusions can be drawn

B.The power of 10 in the solution is –12, the difference of the original exponents.

C.The coefficient is 3, which is greater than or equal to one but less than 10.

D.The quotient is 3.0 × 10^{-12}

Suppose that 21 out of 25 people who apply to a certain college are accepted. What percentage of people who apply are accepted t
IgorC [24]

Answer:

84%

Step-by-step explanation:

The first step is to write 21 as a fraction of 25, which is simply

21/25

Now we just need to convert this fraction to a percentage :

21/25 = 84

So, 21 is 84% of 25
