First you need to divide 125 / 25 which is 5 then you do subtraction 21 x 5 which is 105, then you subtract again 125 - 105 which is 20, 20 light bulbs will be broken. Or you could have just multiplied 5 by 4 which is the amount of light bulbs that were broken which is a lot easier...
Answer:
A
Step-by-step explanation:
AE=EC
5x-10=2x+5
5x-2x=5+10
3x=15
x=5
The answer is c because when you multiply 60 and 0.07 youranswer is 4.2
This equation has one solution which is -1.5
3x+7=-3x-2
+2. +2
3x+9=-3x
-3x. -3x
9= -6x
/-6. /-6
X= -1.5
