Answer:
(1, 6 )
Step-by-step explanation:
5x + 2y = 17 → (1)
4x + y = 10 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 8x - 2y = - 20 → (3)
Add (1) and (3) term by term to eliminate y
- 3x + 0 = - 3
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for x
Substituting into (1)
5(1) + 2y = 17
5 + 2y = 17 ( subtract 5 from both sides )
2y = 12 ( divide both sides by 2 )
y = 6
solution is (1, 6 )
[1 / 8] ÷ [3 / 4]
<span>When dividing fractions, multiply the first fraction by the reciprocal of the second fraction. </span>
<span>So, [1 / 8] ÷ [3 / 4] = [1 / 8] × [4 / 3] </span>
<span>From there, multiply as you would normally. Then reduce it to lowest terms. </span>
<span>4 / 24 = 1 / 6 </span>
<span>Therefore, the answer is 1 / 6.</span>
Answer:
y≥13
Step-by-step explanation:
y-5≥8
y-5+5≥8+5
y≥13
Move the 14 over and get
5x = 2
divide by 5
x = 2/5
