Answer:
Step-by-step explanation:
J = (1/3)M + 2 <=== ur expression would be : (1/3)M + 2
A = 2J - 5
if marcella is 63....
J = (1/3 * 63) + 2 A = 2J - 5
J = 63/3 + 2 A = 2(23) - 5
J = 21 + 2 A = 46 - 5
J = 23 <== justin's age A = 41 <=== Aimee's age

Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67

1/256
Step-by-step explanation:
Answer:
9.2 (1DP)
Step-by-step explanation:
- First you do 10^2 which is 10 X 10 = 100
- Then you do 4^2 which is 4 X 4 = 16
- Then you do 100 - 16. The way Ive learnt it is that if the hypotenuse isn't the one you have to find then minus of it it is then plus. So 100 - 16 = 84
- A^2 + B^2 = C^2 84 is C^2 meaning now you have to square root it
- Square root of 84 is 9.2 to 1 DP
