Answer:
Example:
Cube with sides: 3. V= 3x3x3= ?
Cube with sides: 6. V= 6x6x6=?
How many times bigger is the second answer? That’s it!
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) A = x
Flower garden is in rectangular shape. In rectangle, opposite sides are equal.
2) The entire garden is in rectangular shape. In rectangle, opposite sides are equal.
B + x+ 4 = 10x + 6
Take x and 4 to other side to find the value of B. When taking to other side of equal to sign, the sign of x and 4 will change
B = 10x + 6 - x - 4
B = 10x - x + 6 - 4 {Combine like terms}
B = 9x + 2
3) C + x -2 = 5x -3
C = 5x - 3 - x +2
C = 5x -x - 3 + 2
C = 4x - 1
4) Area of Vegetable garden = length * width
= (5x - 3) * (9x + 2)
Use FOIL method
= 5x *9x + 5x*2 + (-3)*9x + (-3)*2
= 45x² + 10x - 27x - 6
= 45x² - 17x - 6
Answer: Crayfish, 25 s
Step-by-step explanation:
Given
The length of race is 60 cm
Flicker gets a 10 cm head-start
Cray fish covers 6 cm in 5 s i.e. its speed is
Flicker covers 4 cm in 5 s, its speed is
Time taken by Cray fish to cover the race is
Time taken by flicker to cover race with 10 cm head start
Time taken by crayfish is less. Hence, crayfish wins the race
When they both covers the same distance, they tied momentarily i.e.
After 25 s, they tied the race.
Answer:
Step-by-step explanation:
Ellie:; 105/3 = 35 wpm
Vivian: 120/4 = 30 wpm
# of points Farid has = b+35.
So the expression would be b+35.
