Answer:
Step-by-step explanation:
y - 1 + y = 4
2y - 1 = 4
2y = 5
y = 5/2
x = 5/2 - 1
x = 5/2 - 2/2
x = 3/2
(3/2, 5/2)
Answer:
140
Step-by-step explanation:
80 Divied by 4 is 20
SO Each Pair Is 20
7 x 20 = 140
What you would do is simply plug in 8 where y is and solve.
5(8)=3478-3c -Times 5 by 8
40=3478-3c -Add 3c to the opposite side of the equal sign
40+3c=3478 -Subtract 40 from the opposite side of the equal sign
3c=3438 -Divide equation by 3
c=1146
Hope this helps! :)
Answer:
13.5 meters
Step-by-step explanation:
lets take width as w
l=24
and length is 3 meters less than twice the width
so
l+3=2w
24+3=2w
27=2w
divide both sides by "2"
27/2=13.5
13.5=w
