Isaac paid $81 for a new surfboard. The amount paid was 60% of his total savings. How much money did he have in his savings befo

Flauer [41]

Answer:

$135

Step-by-step explanation:

Given data

Amount paid for new surfboard= $81

Percentage of the savings paid= 60%

Let the amount of the savings be x

Hence

60% of x= 81

60/100*x= 81

0.6x=81

x= 81/0.6

x=$135

Hence his savings was $135

I NEED THIS ASAP please. can someone please answer this question i put the picture its on Simplify Expressions im giving 15 poin

Answer:

in step 4

Step-by-step explanation:

we have

$0.5(-12c+6)-3(c+4)+10(c-5)\\\\step1=-12c(0.5)+6(0.5)-3(c+4)+10(c-5)\\\\=-6c+3-3(c+4)+10(c-5)\\\\$

so step 1 is correct

step 2

$-6c+3-3(c+4)+10(c-5)\\\\=-6c+3+c(-3)+4(-3)+10(c-5)\\\\=-6c+3-3c-12+10(c-5)$

so step 2 is correct

step 3

$-6c+3-3c-12+10(c-5)\\\\=-6c+3-3c-12+c(10)-5(10)\\\\=-6c+3-3c-12+10c-50$

so step 3 is correct

step 4

$-6c+3-3c-12+10c-50\\\\=(-6c-3c+10c)+(3-12-50)\\\\=(-6-3+10)c+(-9-50)\\\\=(-9+10)c-59\\\\=c-59$

so step 4 is incorrect
