X is the smaller number. 3x + 15 is the larger number. So x + 3x + 15 = 63. 4x + 15 = 63.
4x = 48. x = 12. (Smaller number) The larger 36 + 15 or 51.
Answer:
X= 38
Step-by-step explanation:
A straight line is 180⁰ so we can subtract that by 133⁰ to get the degree on the inside of the triangle which is 47. You then add 47 and 95 to get 142. To get x you subtract 142 from 180
Answer:
8x+12
Step-by-step explanation:
Remember that perimeter is all the sides combined. A rectangle has the same length and width for both sides.
P=2l+2w
P=2(4x-6)+2(12)
P=8x-12+24
P=8x+12
