Set the equations equal to each other
7x=3x+16
Subtract the 3X
4x=16
Divide by 4
X=4
Then substitute, 7(4)=28
The answer is 28 degrees
Hope this helps
The answer is 20
Explanation: I solved it
Formula for surface are: 2(lw+wh+lh) where l is length, w is width and h is height.
Plug in for 1 - 3
1:
2((16)6 + (6)5 + (16)5)
2(96 + 30 + 80)
2(206)
412 ft²
2:
2((13)5 + (5)6 + (13)6)
2(65 + 30 + 78)
2(173)
346 mm²
3:
2((20)4 + (4)15 + (20)15)
2(80 + 60 + 300)
2(440)
880 in²
The word "of" is the same thing as a multiplication sign!
So instead see it this way:
53% × 470
To solve this, you can use the cross product method :
=
(470 × 63) ÷ 100 = ?
29 610 ÷ 100 = ?
296.1 = ?
53% of 470 is 296.1
There you go! I really hope this helped, if there's anything just let me know! :)
