-3 i think
Step-by-step explanation:
Answer:
Choice 3
Step-by-step explanation:
Using V = πr^2 h
Choice 1. π2^2x6 = 75.4
Choice 2. π2.5^2x5 = 98.17
Choice 3. π3^2x4 = 113.1
Choice 4. π3.2^2x3 = 96.51
The answer is x= -5 ...explained... -2x + 5 -35x= 190...-37x +5 = 190 ... now subtract 190-5 = 185... divide 185 by - 37 and get -5
5/ 1+1= 5/2
1+4/1^2-3(1)-4= 5/-6
5/2 - 5/-6 does not equal zero
Answer:
19
Step-by-step explanation:
Let Sam be x
Let Susan be y
x = y+11
x + y = 27
Substitute (x) with (y+11)
(y+11) + y = 27
Solve the equation
2y + 11 = 27
2y = 16
y = 8
Susan's age is 8.
Sam's age is 8 + 11
Sam's age is 19
Hope this helped :)
