ANSWER EXPLANATION: There are two ways to solve this question. The faster way is to multiply each side of the given equation by ax−2 (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:
24x2+25x−47=(−8x−3)(ax−2)−53
You should then multiply (−8x−3) and (ax−2) using FOIL.
24x2+25x−47=−8ax2−3ax+16x+6−53
Then, reduce on the right side of the equation
24x2+25x−47=−8ax2−3ax+16x−47
Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.
The other option which is longer and more tedious is to attempt to plug in all of the answer choices for a and see which answer choice makes both sides of the equation equal.
The answer is B
Answer: The answer is 4
Step-by-step explanation:
You have the numbers 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5. Then you subtract 7.5 with 3.5 then you get 4. :D
Answer:
w= 15.75 or 15 3/4
Step-by-step explanation:
So I would multiply 100 on both sides to get rid of the decimals so I’d end up with 40w+245=875
Now solve it by subtracting 245 on both sides.
40w=630
now divided 40 on both sides
15 3/4
Final answer 15 3/4 or 15.75
Hi there!
First, we need to find the length of the stage. We can do this by plugging in our known values and solving for the unknown value.
WORK:
252 = 9 x l
l = 28
Next, we know that there are two lengths and two widths total. So all we need to do is to add two lengths plus to widths to find the perimeter.
WORK:
2(28) + 2(9) = P
56 + 18 = P
P = 74 feet^2
Hope this helps!! :)
