There will be three pairs of matching sides: one pair 5x7, one pair 5x12 and one pair 12x7. We can compute the are of each side (in pairs) and then add up the total:

$A_{surf}=2\times(l \times w)+2\times(l \times h)+2\times(h \times w)$
$A_{surf}=2\times(5\times7)+2\times(5\times12)+2\times(12\times7)$
$A_{surf}=2\times35+2\times60+2\times84$
$A_{surf}=70+120+168$
$A_{surf}=358$
$A_{surf}=358m^{2}$

Joan had 198 dollars to spend on 9 books.After buying them she had 18 dollars. How much did each book cost?

Fed [463]

She spent 20 dollars on each book because if you subtract 18 from 198 you'll get 180 then you divide that by 9 n it leaves you with 20.

There are 24 students in Ms. Messing's class 6 more students walk to school then ride their bikes thus number of students who ri

Juli2301 [7.4K]

Walk = x + 6
Bike = x
Driven = x

x + x + x + 6 = 24
combine like terms

3x + 6 = 24
subtract 6 from both sides

3x = 18
divide both sides by 3 to isolate x

x = 6

Walk = x + 6 = 6 + 6 = 12

12 students walk to school.
