Answer:
<h2>x = 20</h2><h2 />
Step-by-step explanation:
∠VRW and ∠TRS form a pair of vertical angles then they are congruent
therefore
3x = x + 40
⇔
2x = 40
⇔
x = 20
Answer:
16
Step-by-step explanation:
12 - 3 = 9
9 + 7 = 16
2x + 3 ≥ 7
2x ≥ 7 - 3
2x ≥ 4
x ≥ 4 / 2
x ≥ 2
2x + 9 > 11
2x > 11 - 9
2x > 2
x > 1
Those are your two inequalities, now we must find one that satisfies both. Combine them together you get:
1 < 2 ≤ x
That last inequality becomes your answer.
x ≥ 2 makes both statements true.
Answer:
$2
Step-by-step explanation:
x = daylily
y = geranium
1x + 5y = 22
13x + 1y = 30
Multiply second equation by 5 and subtract the two equations.
1x + 5y = 22
- (65x + 5y = 150)
-64x = -128
x = 2
So one daylily costs 2 dollars
