Radius times 2 = diameter which would be 10 times 3.14 is 31.4 so it’s 31.4
Let Casey's age be x
Brian's age will be -3 from 2 times x ( Casey's age ) so it will be 2x-3
Adam's age will be Casey's age (x) + 9 which is x+9
NOW the sum of all these ages is 46 so..
Casey's age + Brian's age + Adam's age = 46
x + 2x-3 + x+9 = 46
2x + x + x + 9 -3 = 46
4x + (9 - 3) = 46
4x - 6 = 46
now transfer the numbers on the left one by one to the other side( right )
4x = 46 - 6 ( always remember the sign of the number becomes the opposite when we transfer them to other side)
4x = 40
x = 40 / 4
x = 10
so x = Casey's age = 10
2x - 3 = Brian's age = 2 * 10 - 3
= 20 - 3 = 17
x + 9 = Adam's age = 10 + 9 = 19
Answer:
34, 35, 36
Step-by-step explanation:
1st number = x
2nd number = x+1
3rd number = x+2
So the equation would be:
x+2(x+1)+(x+2)-7=133
x+2x+2+x+2-7=133
4x-3=133
4x=136
x=34
Answer:
I think the answer is 16.
Step-by-step explanation:
If you multiply 3 by 4 you get 12, so if you multiply 4 by 4 you get 16 equaling the fraction of 12/16.
