Answer:
148 minutes = 2h 28 min
Step-by-step explanation:
48min+(25+75mins)=48+100=148
You can get 20 quarters for a five dollar bill. Just divide 5.00 by 0.25 and you get 20. To check, you can multiply 20 by 0.25 and you will get 5.00 or 5.
Y = -2x + 5 y =3x - 2
Since both equations are equal to 'y' you can set them equal to each other to solve.
-2x + 5 = 3x - 2 Subtract 3x from both sides
-5x + 5 = -2 Subtract 5 from both sides
-5x = -7 Divide -5 on both sides
x = 7/5
Plug 7/5 back in for x and solve for y.
y = -2(7/5) + 5
y = (-14/5) + (25/5)
y = 11/5
(7/5, 11/5) OR (1.4, 2.2)
Find x and y intercept and plot
set x to zero and find y
set y to zero and find x
tada, 2 points
if x=0, then y=-4
if y=0, then x=-16
we havee the points
(0,-4) and (-16,0)
or
y=-1/4x-4
4/15 = 0.267
8/25 = 0.32
0.267/0.32 = 0.834375
