Mary and joe are trying to save money for a trip this summer. mary start with $10 and earns $10 each week mowing lawn. joe already has $20 from birthday gifts and earns five dollars a week pulling weeds. how many weeks will it take for mary and joe to have the same amount saved

ANSWERS

Find out the how many weeks will it take for Mary and Joe to have the same amount saved.

To proof

Let us assume that the number of week take for Mary and Joe to have the same amount saved be x.

As given

Mary start with $10 and earns $10 each week mowing lawn.

Joe already has $20 from birthday gifts and earns five dollars a week pulling weeds.

than the equation

10 + 10x = 20 +5x

5x = 10

x = 2 weeks

therefore 2 weeks will it take for Mary and Joe to have the same amount saved.

Hence proved

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
