To solve an area for a triangle you must follow the formula bXh/2
2(4) x 2(2)
A= bXh/2
=8x4/2
=32x6/2
=192/2
=96cm2
Therefore, the area of the triangle is 96cm2.
Answer:
b
Step-by-step explanation:
y=y
x+9 = 2x + 2
x-2x=-9+2
-x=-7
x=7
Answer:
- x < -55
- x ≤ 3
- x > 1
Step-by-step explanation:
x/-5 + 17 > 4
-1/5x + 17 > 4
-1/5x > -13
x < -65
3x - 27 ≤ -18
3x ≤ 9
x ≤ 3
-6x - 1 < -7
-6x < -6
x > 1
Best of Luck!
Answer:
7.5 hours
Step-by-step explanation:
Using the variable 't' for time, you can set up an equation to find out how long it will take the truck to catch up to the bus. Since the bus is traveling at 60mph and the truck is traveling 1 2/3 times faster, we need to first find the rate of the truck:
1
Using 't' and the knowledge that they will have traveled the same distance we the truck catches up to the bus and the fact that the truck left 3 hours later:
60t = 100(t - 3) or 60t = 100t - 300
Solve for 't': 60t - 100t = -300 or -40t = -300 so, t = 7.5 hours
