Answer: 41.16 cm cubed.
= (0.5 • 4.2 • 2.8) • 7 = 41. 16
Explanation: B = 1/2 base times hight of the triangle. Not the figure.
Remember the figure is also tipped over, and its not up right. So you’ll have to try to imagine and image it standing up right.
Step-by-step explanation:
step 1 .simply N/6 equation at the end of step 1 is (7+n/6)-1=0
step 2. rewrite the whole as an equivalent fraction 7=7/1=7.6/6
Answer:
Step-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
<u>Time:</u>
- 120/x = 120/(x + 20) + 1
- 120(x + 20) = 120x + x(x +20)
- 120x + 2400 = 120x + x² + 20x
- x² + 20x = 2400
- x² + 2*10x + 10² = 2500
- (x + 10)² = 50²
- x + 10 = 50
- x = 40
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Answer:
A system of equations is when two or more equations have the same variable(s) that you work with together.
Step-by-step explanation:
For these types of equations, we typically use substitution, elimination, and graphing.
