Answer:
x + 4y = 4
4y = 4 - x
multiply both sides by 1/4
y = 1/4( 4- x)
y = 1- 1/4x
45 ÷ 3 = 15
21 ÷ 3 = 7
12 ÷ 3 = 4
(4 + 15) x 7 = 133
OR if you’re using bedmas/pedmas
4 + (15 x 7) = 109
Answer:
.05
Step-by-step explanation:
to get a percent, you multiply by 100. so take 5 and divide by 100 to get decimal
1 ≤ 3 - x
x + 1 ≤ 3 <em>added x to both sides</em>
x ≤ 2 <em>subtracted 1 from both sides</em>
