Answer:
The solution would be (10, -3)
Step-by-step explanation:
In order to solve using elimination, multiply the top equation by -3 and then add the equations together.
-9x - 12y = -54
9x - 5y = 3
---------------
17y = -51
y = -3
Now that we have a value for y, we can put it into either equation and solve for x.
3x + 4y = 18
3x + 4(-3) = 18
3x - 12 = 18
3x = 30
x = 10

Answer:
u = 156.25
Step-by-step explanation:
Step 1: Write equation
31.25 = u/5
Step 2: Solve for <em>u</em>
- Multiply both sides by 5: 156.25 = u
- Rewrite: u = 156.25
Step 3: Check
<em>Plug in u to verify it's a solution.</em>
31.25 = 156.25/5
31.25 = 31.25
Hey there! :)
(1) Change to decimal and multiply by the number you need to find the % of
75% as a decimal = 0.75
0.75 × 28 = 21
Your answer is 21
_____________________________________________________________
(2) Circumference = π · diameter
To find diameter, divide circumference by π
Circumference = 37.68
37.68 ÷ π = 11.99 = 12
The diameter is 12
Hope this helps :)
