Answer:
the value of x is 50 and the measure of c is 70°
Step-by-step explanation:
x+20+2x-30+40=180 (sum of inside the triangle is 180°)
3x+30=180
3x=180-30
x=150/3
x=50
C = 70 degrees. The steps are shown in the image below. Hope this helps!

Step-by-step explanation:
S=-1-r/5-2
4=-1-r/3

4*3=-1-r
12=-1-r
Collect like terms
12+1=-r
-r=13
Divide both sides by -
r=-13
17/2 = 8.5 hours per week

46% is equal to 14/25
14/25 is equal to 46/100 (multiply 14/25 times 4/4) and that is 46%
Step-by-step explanation:
V = (12*4*5) + (2*3*5) + (5*3*5) + (12*4*5)
V = 240 + 30 + 75 + 240
V = 585 cm^3
