Answer:
49
Step-by-step explanation:
3x+10+6x-20+x+60=10x+50
10x+50=180
10x=130
x=13
A=3*13+10=49
The line through (3,6) and (3,15) is vertical so the perpendicular slope is a horizontal line.
y=7
<u>Part 1)</u> "Four times the difference of a number and is "
Let
x--------> the number
we know that
the expressions is equal to
therefore
<u>the answer part 1) is</u>
<u>Part 2)</u> "One third of a number is less than the number itself"
Let
x--------> the number
we know that
the expressions is equal to
therefore
<u>the answer part 2) is</u>
<u>Part 3)</u> "Ten increased by the quotient of a number and is "
Let
x---------> the number
we know that
the expressions is equal to
therefore
<u>the answer Part 3) is</u>
<u>Part 4)</u> "One less than the product of a number and is more than the number itself"
Let
x---------> the number
we know that
the expressions is equal to
therefore
<u>the answer Part 4) is</u>
