Y * 10 = z

y = dollars
z = dimes

4 dollars = 4y

Replace y with 4:
4* 10 = 40.

Well to find the answer, we must remember that Y stands for Dollars and that Z stands for the number of dimes. We are also provided the amount of dollars (4)

So to find the answer substitute 4 for y in the equation
4 x 10 = Z

Solve for Z
4 x 10 = 40
Z = 40

The number of children at the library was 3 times the number adults. The total number of people at the library was 48. How many
Rufina [12.5K]

Answer:

D 36

Step-by-step explanation:

<em>Write the information algebraically</em>

c = 3a

c + a = 48

c = children, a = adults

<em>In the second sentence (in bold), we can replace c with 3a</em>

c + a = 48 → 3a + a = 48

<em>Simplify</em>

3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)

<em>We can then substitute or plug in a = 12 into the original equation:</em>

c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)

<h3>There are 36 children</h3>

Solve for h.<br><br> h/3 + (-4) + -1
Elden [556K]
There is no answer to this question, as you have not provided us with an equal sign.

If I assume that the equation truly is “h/3+ (-4) + -1 = 0” the answer would be h=15.

Comment down below if there are any specifications on t other parts of the equation.
