Answer:-4ab-7a-6
Step-by-step explanation:
(-6ab-7a+2) - (-2ab+8)
-6ab -7a + 2 + 2ab-8 (removed parentheses & fixed the negative at the end)
-4ab-7a-6 (combined like terms)
X=20. By using the bottom sides of each figure, you can calculate that the figure on the right is 3 times larger than the similar figure on the left. This means that 2x+5=45. When solved, this yields x=20.
Add the kilometers travels by motorcycle and horse together:
3.8 + 3.32= 7.12 kilometers total.
Simplifying
7x + -4y = 23
Solving
7x + -4y = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
7x + -4y + 4y = 23 + 4y
Combine like terms: -4y + 4y = 0
7x + 0 = 23 + 4y
7x = 23 + 4y
Divide each side by '7'.
x = 3.285714286 + 0.5714285714y
Simplifying
x = 3.285714286 + 0.5714285714y
Answer:
The aquarium needs 56 more gallons to be completely filled.
Step-by-step explanation:
To get the amount remaining you have to first divide 1120 by 100
1120/100=11.2
Then multiply it by 95
11.2*95=1064
You take the maximum amount (1120) and subtract the amount in the tank (1064) to get the amount left.
1120-1064= 56
With 56 gallons as your final answer.
