Answer:
52
Step-by-step explanation:
b(a+b) is equal to 4(9+4)
then you want to multiply 4x9 and 4x4
4x9=36 and 4x4=16
then add 36 and 16 you get 52
or
b(a+b) is equal to 4(9+4)
add 9+4
9+4=13
then you get 4(13)
multiply 4x13 and you will get 52
4x13=52
The answer to the following question is 61

5x - 11 < -11
5x < 0
x < 0
4x + 2 > 14
4x > 12
x > 3
x<0 or x > 3
x=0 or x=4
just factorize basically
cancels the x’s so it’d be 3x-12=0 and from that x=4
The ratio of 186:76 can be simplified to 93:38 if we divide both numbers by 2.
Answer:
see below
Step-by-step explanation:
x - 2/5= 7
Add 2/5 to each side
x - 2/5 + 2/5 = 7+2/5
x = 7 2/5
or if
( x-2) /5 = 7
Multiply each side by 5
(x-2) /5 *5 = 7*5
x-2 = 35
Add 2 to each side
x-2+2 = 35+2
x = 37
Answer:
22.25 or 22
Step-by-step explanation:
360-276+=84
4x-5=84
