Using a rule is direct and not time wasting, which is not the case for listing functions
Answer:
It would be $13 as the original bill
But the correcy answer is D
Step-by-step explanation:
Answer:
144
Step-by-step explanation:
angle A + angle B = 180 (supplementary angle)
A = 4B
4b+b=180
5b=180
Divide 5 on both sides to get b=36
180-36= measure of angle A
180-36=144
Answer: x < 8/9
Step-by-step explanation:
The equation is 4 * (2x +1) * 4.5 = 50, since the volume is found by multiplying the length, width, and height together, and the =50 part is because our volume can't go above 50 cubic units.
We can simplify 4 * (2x+1) * 4.5 by multiplying 4 and 4.5, which is 18, and then multiplying both 2x and 1 by 18. We get 36x + 18, and we put in the =50, so it is 36x+18=50.
Next, we can subtract 18 from both sides of the equation, giving us 36x = 32.
We then divide the equation by 36 so that we have the x by itself, and we get x = 32/36, which can be simplified to 8/9.
What we're left with is x = 8/9, meaning plugging in 8/9 for the equation would give us 50. However the problem says that the volume must be below 50, so our actual answer is x < 8/9.
