Solve the formula Ax+Bx = c for y

Mathematics
1 answer:
IgorC [24]3 years ago
3 0

Answer:

B

Step-by-step explanation:

The correct formula given is:

Ax+By=c

We need to solve for y. First, we isolate the "y" term:

Ax+By=c\\By=c-Ax

Now, there's a "B" with y, to isolate the "y", we need to divide both sides by "B" and get "y":

By=c-Ax\\\frac{By}{B}=\frac{c-Ax}{B}\\y=\frac{c-Ax}{B}

Answer choice B is right.

Jane= x-5

Tom= (x+8)-5=>x+3---------------------------
x+3=3(x-5)<span>x+3=3x-15
3x-x=18

A person invest $3000 in a bank the bank pays 6.75% interest compounded semi annually to the nearest 10th of a year how long mus
Monica [59]

Answer:

It would take 12.1 years.

Step-by-step explanation:

We are given with $3000 invested in bank pays 6.75% interest compounded semi annually to the nearest 10th. We are asked to find the number of years the bank reaches $6700.

Let's use the compound interest formula.

A= P(1+\frac{r}{n}) ^{nt}

We know A=6700

P=3000

r =0.0675

n=2(because compounded semiannually)

t =?( we need to find it)

Plug in the known values into the formula.

6700=3000(1+\frac{0.0675}{2}) ^{2*t}

Simplify and solve for 't'

Divide both sides by 3000

2.23333= (1.03375)^{2t}

Take log on both sides

log(2.23333) = 2t log(1.03375)

Divide both sides by log(1.03375)

24.2067=2t

Divide both sides by 2.

t=12.10...

To round to nearest 10th, we get t=12.1 years.
