The sum of three numbers is 85. the second is 7 more than the first. the third is 2 more than four times the second. find the numbers.

"The sum of three numbers is 85"

x+y+z = 85

"The second number is 7 more than the first."

y = x+7

"The third is 2 more than four times the second."

z = 4y+2

z = 4(x+7) + 2 = 4x+30

x + (x+7) + (4x+30) = 85

6x = 48

x = 8

y = x+7 = 15

z = 4x+30 = 62

Hope this helps!

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
