Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
30%of 68 = 30/100*68= 3*68/10=204/10=20.4

Answer:
69,286,455 cu inches
Step-by-step explanation:
<u>Step 1: Convert yards to inches</u>
1 cu yard = 46656 cu inches
11 cu yard = y cu inches
<em>Cross multiply</em>
y = 11 x 46656
y = 513216 cu inches
<u>Step 2: Find total inches</u>
513216 + 17 = 513233 cu inches
<u>Step 3: Multiply total inches by 135</u>
513233 x 135 = 69,286,455 cu inches
