Answer:
The width of the bathroom is 10ft.
Step-by-step explanation:
To find the area of a rectangle, we use the formula
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>area</em><em> </em><em>=</em><em> </em><em>width x length</em>
So we know that length is equal to 7 ft, and we also know the total area which is 70 sq.ft.
70 = ? x 7
multiplication and division are inverse operations, so we will divide instead
70 divided by 7 = 10
And we are done!!
hope this helps you, feel free to leave any questions in the comments!! :)
Let H represent hardcover
let P represent paperback
H + P = 20
H = P + 10
sub in H into the first eq’n
(P + 10) + P = 20
2P + 10 = 20
2P = 10
P = 5
sub P into eq’n 2
H + (5) = 20
H = 15
therefore there are 5 paperback books and 15 hardcover
1063 ÷ 10 = 106.3
1063 ÷ 106.3 = 10
