Step-by-step explanation:
<u>Step 1: Define</u>
2(x/4 + 8) = 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 2 on both sides: x/4 + 8 = 9
- Subtract 8 on both sides: x/4 = 1
- Multiply 4 on both sides: x = 4
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(4/4 + 8) = 18
- (Parenthesis) Divide: 2(1 + 8) = 18
- (Parenthesis) Add: 2(9) = 18
- Multiply: 18 = 18
Here we see that 18 does indeed equal 18.
∴ x = 4 is the solution to the equation.
Answer:
-1
Step-by-step explanation:
Answer:
a)5:2
b)14
c)17
Step-by-step explanation:
The ratio for babies to nursery workers is 5:2
To find the answer to b, we find how much you have to multiply 2 by to get 35, which is 7 and multiply that by the number of workers, 2, so you need 14 workers
To find the answer to c multiply 2 bye 3.5 to get 7 and multiply 5 by 3.5 to get 17.5 now rounf down so the answer to c is 17
