Let multiply by 35 both sides of the equation
35b+35*3/7=35*2/5
35b+15=14
There are all false
Answer:
138 packs
Step-by-step explanation:
Marcello thinks it better to have more water balloons on hand that he actually needs fo the water balloon fight, so he rounds up the number of balloons needed to 276 from 275.
Then he divides 276 by 2, obtaining 138. He needs to buy 138 packets of balloons. This way, he will have acquired the required 275 balloons plus 1 left over.
Answer:
1/3 RISE/RUN
Step-by-step explanation:
Answer:
a = - 2 and b = - 3
Step-by-step explanation:
Distribute the parenthesis on the left side then compare like terms on both sides.
4(3x - 6) - 7(2x + b)
= 12x - 24 - 14x - 7b
= - 2x - 24 - 7b
Compare to right side ax - 3
For the 2 sides to be equal then
- 2x = ax ⇒ a = - 2
and
- 24 - 7b = - 3 ( add 24 to both sides )
- 7b = 21 ( divide both sides by - 7 )
b = - 3
You should put 4 as x, -3 as y and a as slope to make an equation :
then you can find the slope and the correct equation of the line :
the slope is :
so the equation of the line will be
D is true
hope this helps
