Answer: 15) 97
16) 16
17) 24
Step-by-step explanation:
15) (x-75) + (x-52)+ 293=360
x - 75 + x - 52 + 293 = 360
2x - 127 + 293 = 360
2x + 166 = 360
2x = 194 [Subtract 166 from both side]
x = 97 [Divide by 2 from both side]
16) (4x+15)+(5+6x)=180 The angle of a straight line is 180.
4x + 15 + 5 + 6x = 180
10x + 20 = 180
10x = 160 [Subtract 20 from both side]
x = 16 [Divide by 10 from both side]
17) (x+17)+(2x+1)= 90 These two angle combined equal to 90.
x + 17 + 2x + 1 = 90
3x + 18 = 90
3x = 72 [Subtract 18 from both side]
x = 24 [Divide by 3 from both side]

Answer:
158
Step-by-step explanation:
Simplify the following:
2×5×3 + 2×5×8 + 2×3×8
5×3 = 15:
2×15 + 2×5×8 + 2×3×8
5×8 = 40:
2×15 + 2×40 + 2×3×8
3×8 = 24:
2×15 + 2×40 + 2×24
2×15 = 30:
30 + 2×40 + 2×24
2×40 = 80:
30 + 80 + 2×24
2×24 = 48:
30 + 80 + 48

Step-by-step explanation:
<u>Exponential Growing
</u>
Steven currently reads 2 books a year. He wants to triple the number of books read per year. The first year he should read
By the second year, he should read
By the third year, he should read
We can clearly see there is a geometric progression of the number of books he should read for the year n. The general formula is, being B the number of books read at the year n
