Answer:
Multiply both sides by 2
Subtract l from both sides
Divide each side by 3
(2R -l)/3 =w
Step-by-step explanation:
R = (l+3w)/2
Multiply both sides by 2
2R = 2* (l+3w)
2R = l+3w
Subtract l from both sides
2R - l = l-l +3w
2R -l = 3w
Divide each side by 3
(2R-l) /3 = 3w/3
(2R -l)/3 =w
Answer:
123°
Step-by-step explanation:
Supplementary angles add up to be 180 degrees.
This means angles A and B will add up to be 180 degrees.
We can find the measure of angle B by subtracting 57 from 180
180 - 57
= 123
So, the measure of angle B is 123 degrees
13-4x=1-x
13=4x+x=1-x+x
13-3x=1
13-1-3x=1-1
12-3x=0
12=3x
12/3=3x/3
4=x
Therefore, x=4
Answer:1500
Step-by-step explanation: so i got the anwser 1539.2 and just rounded to the nearest hundredth which is 1500 hopefully it helps!
Answer:
These two figures are similar because 
equals 
Step-by-step explanation:
The figures will be similar if their ratios of the two sides are equal. So we need to check the ratios of the figures to see if they are similar or not.
For the smaller figure the ratio is , and for the bigger figure the ratio is which upon simplification reduces to .
So we see that the ratios are equal. Thus the figures are similar.
