The answer is 20-3x=-7 explanation
That equals 3871 hope it helps
So the second question asks about the perimeter of a rectangular pool and the answer for that is W=87m.
I don’t know about the first question sorry but I’ll try figuring it out.
I will put an equation to the corresponding number.
1) Seven more than 2 times a number is 23 => 2n + 7 = 23
2) The difference of 2 times a number and 7 is 23 => 2n - 7 = 23
3) The sum of 7 times a number and 2 is 23 => 7n + 2 = 23
4) Seven less than 2 times a number is 23 => 2n - 7 = 23
Based on the choices. The equation that matches sentences 2 & 4 is letter b. 2n - 7 = 23
Though both sentences are structured differently and used different terms, they both refer to subtraction of 7 from the product of 2 and n to get the difference of 23.
Answer:
yes; you can just remember that all the angles on a triangle equal 180 so just add the two angles, subtract from 180 to get your last angle degrees.
