Answer:
5 and -5
Step-by-step explanation:
Opposite numbers are the same distance from 0 on the number line. So, each of the numbers is a distance from zero that is half the distance between them.
The numbers are 10/2 = 5, and -5.
Step-by-step explanation:
180 -angled triangle,
180-56 = 124
124/2 = 62 (each corner of the right triangle)
then find the corner below
the rectangle has right angles on the right side
x = 90-62
= 28

Answer:
Step-by-step explanation:
x= -1 and -3
What when multiplied is +3 but when added is 4? 3 and 1. You then get (x+3)(x+1) is the first part of the answer. If you want to find x, set x+3 to 0. x+3=0. Then subtract 3 from both sides to get x by itself. x= -3. Do the same with the x+1.
Answer:
x = (64 + 5) ÷ 3
Step-by-step explanation:
3x - 5 = 64
Add 5 to both sides: 3x = 64 + 5 = 69
Divide both sides by 3: x = 69 ÷ 3 = 23
So the answer is x = (64 + 5) ÷ 3
Note: If we didn't add the parentheses then using the order of operation x = 64 + 5 ÷ 3 would be x = 64 + 
= 65
