x=5
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(−x+1)+3x+3=26
Answer:
Hello there the Correct answer The only answer choice that produces -2x²+2 is D.
Because (-x²+2x+3)+(-x²-2x-1) = -x²+2x+3-x²-2x-1 = -2x²+2
answer: D
Hope It Helps!
570 is the answer. since 1000 has 3 zeroes on the end of it, you take the decimal point and move it 3 spots to the right.
The answer would be 17.
This is because, the format for finding out the hypotenuse of a triangle is--
a^2 + b^2 = c^2
So, it would translate to--
15^2 + 8^2 = c^2
225 + 64 = 289
Because 289 = c^2, you need to take the square root of it.
The square root of 289 is 17.
Therefore, your answer is 17.
Answer:
93
Step-by-step explanation:
Setup an equation. Add the 5 tests together, the unknown test will be represented by x, Since there are 5 tests total, you will divide by 5. to find the average.

To solve first multiply both side by 5.


Add the left side and then solve for x

Subtract 357 from both sides
357 - 357 + x = 450 - 357
x = 93
The last test has to be a score of 93 to get an average of 90.
