Answer:
1.36 for the first one
1.875 for the second one
1.3 repeating for the third one
0.5 repeating for the fourth one
0.3 for the fifth one
Step-by-step explanation:
Don't sweat it. It looks complex but i will try to help explain it.
First all this equation ids saying is 8 times a number k divided by 3=32
So,First we get rid of the three.So it says divide by three so we do the opposite operation. So.So 32*3=96
Now we have 8k=96
So our goal is to get x by it self so we divide by 8 because we need to do do the opposite operation.
We get x=12
If you follow the pattern the y value is the x value multiplied by 4
5 x 4=20
Y=20
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:
