Step-by-step explanation:
Suppose, John walks with a speed x
Then, John can jog at a speed 2x
TOTAL TIME
Further solving :
x = 5 mph
Average jogging speed (2x) = 10 mph
Answer:
x=1 y=2
Step-by-step explanation:
Isolate x for 4x -y =2: x=2+y/4
Substitute x= 2+y/4
(2+13y/4) +3y=7
simplify 2+13y/4) =7
Isolate y for 2+13y/4) =7: y=2
Forx= 2+y/4
Substitute y =2
x=2+2/4
x=1
3(6m)+m *Distribute
18m+m *Simplify/Add
19m
19m=19m :)
44×$20=$880. so the answer is $880
Begin by multiplying everything by 3 to get rid of the fraction. That gives us
. The rule is when you divide by a negative, the direction of the sign changes, so we will end up with
. Because there is a line under the inequality sign, the circle is closed. So your choices are the second, fourth, and sixth.
