45/60= .75 miles each minute
45x2= 90 miles in 2 hours
.75×20=15 miles in 20 min
90+15=105 miles in 2 hours n 20 min
Answer:
D.3.5
Step-by-step explanation:
4x+2y=10(given)
2x+y=5
y=5-2x-----(1)
y=2x-1------(2)(given)
Since the left side of the equations are the the same,
5-2x=2x-1
4x=6
x=1.5
Sub x=1.5 into eq(1),
y = 5-2(1.5) = 5-3 = 2
so, x+y = 1.5+2 = 3.5
That is one half also 1/2 if this was not what u where looking for then just tell me
Answer:
12 2/12
or 12 1/6 ( simplified fraction)
Step-by-step explanation:
first add the whole numbers together :7+5-4+3=12-1=11 ( same denominator 12)
1/12 +7/12 -5/12 +11/12 = 14/12 ( improper fraction)
= 1 2/12 mixed fraction
11 + 1 2/12=12 2/12 or 12 1/6 ( simplified fraction)
