Answer:
I would say you are correct with your answer
Step-by-step explanation:
hope it is correct
x + y = 54
x - y = 10
Add them to get: 2x = 64
x = 32
and plugging in x = 32 to either eqn: y = 22
Ans: the numbers are 22 and 32
Answer:
a) 6/9
b) 66.66%
Step-by-step explanation:
a) Total number of the small triangles inside the big triangle=9
and the shades = 6
friction of shaded = 6÷9
b) percentage of shaded = 6÷9 ×100
=66.6666%
X = 60°
Because the square in the corner tells you that it is 90° (right angle)
So your equation to solve for x would be...
x + 30 = 90
Now you need to isolate the x.
Subtract both sides by 30.
x + 0 = 90 - 30
x = 60
