Answer:
Simplifying
8x + 17 = 137
Reorder the terms:
17 + 8x = 137
Solving
17 + 8x = 137
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + 8x = 137 + -17
Combine like terms: 17 + -17 = 0
0 + 8x = 137 + -17
8x = 137 + -17
Combine like terms: 137 + -17 = 120
8x = 120
Divide each side by '8'.
x = 15
Simplifying
x = 15
Answer:
<u>39.28cm^2 </u>
Step-by-step explanation:
Simple work out the area of a circle and halve it.
3.142xr^2
3.142x5^2 = 78.55 cm^2 (Full circle area)
Now we must halve that answer to get the semicircle.
78.55/2 = 39.275 cm^2
However, we need it to 2dp. Therefore the answer is 39.28cm^2

Answer:
Let's denote:
x: number of bicycles
y: number of skateboards
Then, we have:
x + y = 20
2x + 4y = 52
=> 2(20 - y) + 4y = 52
=> 2y = 12
=> y = 6 (number of skateboards)
=> x = 14(number of bicycles)
Hope this helps!

7 stamps* ($2.20/ 5 stamps)= $3.08.
(Note that the unit cancels out so you get the answer)
The final answer is $3.08~
