Answer:
1) James brother is 10-x years old
2) James was 3 years ago x-3 years old
3) James brother was 3 years ago 7-x years old
4) 3(x-3)=7-x
5) James is 4 years old, his brother is 6 years old
Step-by-step explanation:
3) 10 - x - 3 = 7 - x
5) 3* James age 3 years ago = James brothers age 3 years ago
<=> 3*(x-3) = 7-x
<=> 3x - 9 = 7 - x
<=> 4x = 16
<=> x = 4
Answer:
256
Step-by-step explanation:
First..
8*2=16
Now
16 (squared)=256
Hey there!
To find the x-value of the midpoint, you add the two x-values of the endpoints and the divide the result by two.
-12+0=-12
-12/2=-6
So, the x-value of our midpoint is -6.
To find the y-value of a midpoint, you do the same thing as with the x-values but with the y-values.
2+14=16
16/2=8
Our y-value is 8.
Therefore, our midpoint is (-6,8)
I hope that this helps!
Answer:
5
Step-by-step explanation:
200/2=100 then after 100 u divide card by 2 so 100/2 and that's 50 and then last divide by 10 because its the circumference so its 5
