Answer:
boys + girls = 45 -------(1)
There boys 17 more than girls, boys = girls + 17 ----------(2)
substitute (2) in (1)
girls + 17 + girls = 45
2 x girls + 17 = 45
2 x girls = 45 - 17
2 x girls = 28
girls = 14
substitute in (2): boys = girls + 17 = 14 + 17 = 31
option D
80 + 5 is 85 in extended form
Answer:
14
Step-by-step explanation:
3 + 2 + (5 - 1) + 5
Always solve the ones inside the parentheses first.
3 + 2 + (4) + 5
5 + 4 + 5
9 + 5
= 14
Answer:
9
Step-by-step explanation:
Isolate w by dividing by -2.
Answer:
y^3 =30
y= (30)^(1/3) ------(1)
z=10 -------(2) -----(2)
From (1) and (2);
(y * z)^12 = (y)^12 * (z)^12
= ((30)^(1/3))^12 * (10)^12
= (30)^(12/3)* (10)^12
= (30)^(4) * (10)^12
= 810 000 * (10)^12
= 81 * (10)^16
