R = 5(CA - 0.3)
<span>Multiply everything in the parenthesis by 5.</span>
R = 5CA - 1.5
Add 1.5 to both sides
1.5 + R = 5CA
Divide 5A on both sides.
C = 1.5 + R / 5A
Hope this helps!
Answer:
50% of 180 is 90
Step-by-step explanation:
50% is like saying half. They want you to find half of 180, if you know 9 times 2 equals 18, then you already know the answer, all you have to do is add a 0 on the end of the 9.
Or if you're not as strong with mental math, plug into a calculator 180 times the decimal version of 50% which is .5. 180 times .5 equals 90.
85 %
85/100 - divide by 5 for the numerator and denominator
85/5= 17
100/5=20

Answer:
angles on a straight line add up to 180°
Step-by-step explanation:
90+51=141
180-141
=31
<MLJ=31°
72+90=162
180-162=18
<KJL=18°
