first you should go left to right when solving these equations:
5/12 ∙ 1/5
= 5/60
Then you multiply 5/60 and 8
5/60 ∙ 8/1 (8/1 is still a whole number. It makes it easier to multiply)
= 40/60 = 2/3
So, the answer is 2/3.
To do this you just have to do 18 × 5
which equals 90
hope this helps
Answer:
x=12
Step-by-step explanation:
Im not sure which measure you're talking about, but I'll show you what I did here:
A triangle = 180 degrees.
4x + 8x + 4x =16x
-8 - 1 - 3 = -12
180 = 16x - 12 -Add 12 to both sides
192 = 16x -divide by 16 to get x by itself
12 = x
Angle A = 88 degrees (8 times 12 then subtract 8)
Angle B = 47 degrees (4 times 12 then subtract 1)
Angle C = 45 degrees (4 times 12 then subtract 3)
Y=-1/2x+5 because the y intercept of the two points is 5
