A = L * W
A = 20 * 24
A = 480 sq ft.....so her garden is 480 sq ft.
1 qt of fertilizer covers 300 sq ft....so how many quarts will cover 480 sq ft.
set this up as a proportion
1/300 = x / 480....1 qt to 300 sq ft = x qts to 480 sq ft
cross multiply
(300)(x) = (1)(480)
300x = 480
x = 480/300
x = 1.6.....so Danielle will need 1.6 qts to cover her garden <==
Answer:
x=4
Step-by-step explanation:
1/3 (20 + x) = 8
multiply both sides of equation by reciprocal of 1/3
3/1 * 1/3 (20 + x) = 8 * 3/1
20 + x = 24
subtract 20 from both sides
x = 4
Answer:
yes
Step-by-step explanation:
I’m pretty sure it’s the one with the r and s
so the second option!
Answer:
$108
Step-by-step explanation:
<u>Use the equation i = prt </u><u>(interest = principle*rate*time)</u><u>:</u>
Principle: $900
Rate: 0.06 (6%)
Time: 2 years
<u>Put it all in an equation:</u>
i = 900*0.06*2
i = $108
