Answer:
- Abel is 7 and Asare is 17 years old
Step-by-step explanation:
Let the age of Abel is x and age of Asare is y.
Three times the age of Abel is four more than the age of Asare:
And
In three years, the sum of their ages will be 30 years:
We got two equations.
Simplify and solve by substitution:
- 3x - 4 + x = 24 Substitute y
- 4x - 4 = 24
- 4x = 28
- x = 7
Find y:
Answer: 48
Step-by-step explanation: All you are doing is substituting x and y with the numbers it gives u then u just solve. 2 to the 4th power is 16. 4 to the 3rd power is 64 and then times .5 gives u 32. then u add and get 16+32=48
Answer:
<1 + <2 = 180
Step-by-step explanation:
Looking at the diagram
<1+<2 forms a straight line so they add to 180 degrees
<1 + <2 = 180

0.5a+8.75=13.25
We simplify the equation to the form, which is simple to understand
0.5a+8.75=13.25
We move all terms containing a to the left and all other terms to the right.
+ 0.5a=+13.25-8.75
We simplify left and right side of the equation.
+ 0.5a=+4.5
We divide both sides of the equation by 0.5 to get a.
a=9
Answer:
Answer is below
