Answer: Angle OZP= 62 Angle PZQ=63
(4r+2)+(5r-12)=125
9r-10=125
9r=135
r=15
Angle OZP Angle PZQ
4(15)+2 5(15)-12
62 63
A two-digit number is twice the sum of its digit. If the tens digit is 7 less than the unit digit, find the number.
Let x= the unit digit
Then y= the tens digit
<span>And 10y+x= the number
</span>x+y= the sum of the digits
<span>Now we are told that 10y+x=2(x+y) ------1st equation </span>
<span>We are also told that y=x-7 ----------- 2nd Equation </span>
<span>So our equations to solve are: </span>
(1) 10y+x=2(x+y)
<span>(2) y=x-7
</span>
Hope it helps
