This is a practice asaigment before the real assignment plz help

1)a+$5.92=$12.29

a= $12.29-$5.92

a=$6.37

2) 42/j = 6

6j=42

j=42/6

j=7

3) j+8=72 —> 9+8=72–>17=72 False

m x 3= 27 —> 9x3=27 —> 27=27 True

b+4=13 —> 9+4=13 —> 13=13 True

p-5=4 —> 9-5=4 —> 4=4 True

q/3 = 27 —> 9/3 =27 —> 3=27 False

4) $15.32+ C= $29.00

For soccer ball: C= $12.87

$15.32+ C= $29.00 —> $15.32+ $12.87 = $29.00 —> $28.19

For baseball cap: C=$8.39

$15.32+ C= $29.00 —> $15.32+ $8.39 = $29.00 —>$23.71

For a set of shin guard: C=$14.98

$15.32+ C= $29.00 —> $15.32+ $14.98 = $29.00 —>$30.3

For water bottle: C=$5.93

$15.32+ C= $29.00 —> $15.32+ 5.93 = $29.00 —>$21.25

Because annabetg can spend only $29 at the store, the most expensive item she can buy with the t-shirt is the soccer ball which cost $12.87

5) 6x=12–> x=12/6 —> x=2 False

5+x=11 —> x=11-5 —> x=6 True

x/2=3 —> x= 2x3 —> x=6 True

17-x=11 —> -x=11-17 —> -x=-6 —> x=6 True

Note: Review part 4 please or ask someone to resolve it to make sure it is correct
