Answer:

y = 8

Step-by-step explanation:

Hello!

We can solve for y by isolating it.

<h3>Solve for y</h3>
  • 3y - 15 = y + 1
  • 3y - 15 - y = y +1 - y
  • 2y - 15 = 1
  • 2y - 15 + 15 = 1 + 15
  • 2y = 16
  • y = 16/2
  • y = 8

The value of y is 8.

<h3> 3y ➖15 = y ➕ 1</h3>

<em>We move all terms to the left:</em>

<h3>3y ➖ 15 ➖ (y ➕ 1) = 0</h3>

<em>We get rid of the parentheses.</em>

<h3>3y ➖ y ➖ 1 ➖ 15 = 0</h3>

<em>We add all the numbers and all the variables.</em>

<h3>2y ➖ 16 = 0</h3>

<em>We move all terms containing y to the left side, all other terms to the right side</em>

<h3>2y = 16</h3><h3>y = 16/2</h3><h3>y = 8</h3>

How do I translate the product of h and 4 is subtracted from one-fifth of x is 35 to an equation?
kolezko [41]

So we know that the word 'product' means multiplication, and that means that h and 4 are being multiplied. Also, one-fifth of x is another way of saying that one-fifth is being multiplied with x. So then we can construct the equation:

\frac{1}{5} x-(4*h)=35

And we can then simplify this by taking out the multiplication sign:

\frac{1}{5}x-4h=35

And so since we do not know what x or h is equal to, this is as far as we can go.

Last year, Maria had $10,000 to invest. She invested some of it in an account that paid 6% simple interest per year, and she inv
denis-greek [22]

Answer:

$3,000 invested at 6%

$7,000 invested at 10%

Step-by-step explanation:

Maria had total $10,000 to invest.

Let x be the amount that Maria invested initially at 6% interest rate.

0.06x

Then she invested the remaining amount at 10% interest rate.

0.10(10,000 - x)

She received a total of $880 in interest.

0.06x + 0.10(10,000 - x) = 880

0.06x + 1000 - 0.10x = 880

-0.04x = 880 - 1000

-0.04x = -120

0.04x = 120

x = 120/0.04

x = $3,000

This is the amount that Maria invested initially at 6% interest rate.

The remaining amount is

10,000 - 3,000

$7,000

This is the remaining amount that she invested at 10% interest rate.
