Answer:
×=2
Step-by-step explanation:
5x+5=15
5×=10
×=2
.........
(4/5) / (4/9) = 4/5 * 9/4 = 36/20 = 9/5 = 1 4/5 miles per hour
so B.) one and four-fifths mph
Solve for y in 4x+y=11
4x + y = 11
<span>y = 11 − 4x
</span>Substitute <span>y = 11 - 4x</span> into <span>8x + 2y =13
22 = 13
</span>Since <span>22 = 13</span><span> is not true, this is an inconsistent system.
</span>
So, no solution.
