Answer:
40 km/h and 60 km/hStep-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
Time:
120/x = 120/(x + 20) + 1120(x + 20) = 120x + x(x +20)120x + 2400 = 120x + x² + 20xx² + 20x = 2400 x² + 2*10x + 10² = 2500(x + 10)² = 50²x + 10 = 50x = 40Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h

Find the value of x.
56°
57°
85
2x
4x
Answer:
56
Step-by-step explanation:
Simplifying
x + 7x = 56 + 8
Combine like terms: x + 7x = 8x
8x = 56 + 8
Combine like terms: 56 + 8 = 64
8x = 64
Solving
8x = 64
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '8'.
x = 8
Simplifying
x = 8

The spider would reach the height of 74 cm on 24th February by the end of the day.
What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given is that a spider is climbing up a wall. During the daytime it climbs 5 cm, but then slips back 2 cm during the night.
The net distance covered by the spider in one day -
D{n} = 5 cm - 2 cm = 3cm
The spider would reach 74 cm up in -
{x} = 74/3
{x} = 24.7
This means that the spider would reach the height of 74 cm on 24th February by the end of the day.
Therefore, the spider would reach the height of 74 cm on 24th February by the end of the day.
