How do you solve -9x+5(8x-7)?

Mathematics

Ivahew [28]3 years ago

Answer:

distribute the +(positive) 5 to the numbers in the parenthesis (8x-7) and solve it from there! it is left as an expression, because you can't add a variable with an integer

Step-by-step explanation:

5*8x=40x

5*-7= -35

so it's: -9x+40x-35 which also equals 31x-35

Answer: 31x - 35

Let’s start by rewriting the equation

-9x+5(8x-7)

Now let’s distribute

-9x+5(8x-7)

-9x+40x-35

Now we need to combine like terms. These are numbers that share the same variable, or lack of.

-9x + 40x -35

31x - 35

Since there is no equal sign, this is as simplified as this equation can get. If you need more help feel free to comment below :)

Y is 60% of 40

Equation: Y = P% * X

<u>Solving our equation for Y</u>

Y = P% * X

Y = 60% * 40

For her college fund jenny's parents invested $5000 four years ago. the account has now reached $6312. what is the approximate a
Tasya [4]

Answer:

Rate = 6.56%

Step-by-step explanation:

Principal (P) = $5000

Interest (I) = $6312

Time (T) = 4 years

Rate (r) = ?

This question is involves simple interest and with the formula, we can easily plug in the values to find the rate.

S.I = P(1 + rt)

S.I = simple interest

P = principal

R = Rate

T = Time

6312 = 5000(1 + r*4)

6312 = 5000 + 5000*4r

6312 - 5000 = 20000r

1312 = 20000r

r = 1312 / 20000

r = 0.0656

Rate are calculated in percentage hence we'll multiply it by 100

R = 6.56%
