Add the values, then you get the answer.
55+67 = ?
55
+ 67
------------
122
Final answer: $122 is how much Jordan has.
Let's call he width of the notebook w and the length l
w*l=80
2(w+l)=36
w+l=18
w=18-l
(18-l)*l=80
-l^2+18*l-80=0
l=8 or 10
Therefore, the notebook is 8 by 10 inches
The answer is YON. x-intercept = (-1, 0)
y-intercept = (0, -3)
When you are writing an intercept, the other variable is 0.
For x-intercepts: (x, 0)
For y-intercepts: (0, y)
Answer:
55mph
None of the option is correct
Step-by-step explanation:
Let v be the speed and t as the time taken. If speed varies inversely as the time it takes to drive, then v ∝ 1/t.
v = k/t where k is the constant of proportionality.
IF it takes Kris 5 hours when driving at 55 mph, then v = 55mph when t = 5 hours.
Substituting this values into the formula above;
55 = k/5
k = 55*5
k = 275mp/hr²
To calculate the speed it will Martin to drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t
v = 275/5
v = 55 mph
<em>Hence, martin will also need to drive at 55mph to take 5 hours</em>
We can have different variables to represent each brother (there can be different variations and ways to solve, but I'll do it my way).
Matt=m
Jeff=3m
Todd=m+25
Matt Jeff Todd
m+3m+(m+25)=275 3(50) 50+25
5m+25=275 =150 =75
5m=250
m=50
Matt spent $50, Jeff spent $150 and Todd spent $75
Check:
50+150+75
=$225
