Paul's age = 6 years + Corinne's age
<span>(Paul's age - 10 years) = 3 times (Corinne's age - 10 years) </span>
<span>Let's rewrite it so it's cleaner: </span>
<span>P = 6 + C </span>
<span>P - 10 = 3(C - 10) </span>
<span>Question is P = ? years. </span>
<span>P = ? = 6 + C </span>
<span>We need to know what C is... the second equation can tell us: </span>
<span>P - 10 = 3C - 30 </span>
<span>P + 20 = 3C </span>
<span>P/3 + 20/3 = C </span>
<span>So now we know what C is... we can replace it into the first equation: </span>
<span>P = 6 + [P/3 + 20/3] </span>
<span>we just need to simplify now... it's easiest to get rid of the fractions first: </span>
<span>3P = 18 + P + 20 </span>
<span>2P = 38 </span>
<span>P = 19 </span>
<span>Answer is Paul's age is now 19 years.</span>
Answer:
337.5
Step-by-step explanation:
50÷2 = 25
75÷2 = 25
13.5×25 = 337.5
Answer:
11/12 ÷ 1/3 = 2 and three-fourths
11/12 ÷ 1/3 = 2 3/4
Step-by-step explanation:
What is StartFraction 11 Over 12 EndFraction divided by one-third? A fraction bar labeled 1. Under the 1 are 3 boxes labeled one-third. Under the 3 boxes are 4 boxes containing one-fourth. Under the 4 boxes are 12 boxes containing StartFraction 1 Over 12 EndFraction. 2 and one-fourth 2 and three-fourths 3 and one-third 3 and two-thirds
Given:
11/12 ÷ 1/3
= 11/12 × 3/1
= 33 / 12
= 2 9/12
= 2 3/4
= 2 and three-fourths
11/12 ÷ 1/3 = 2 3/4
Answer:
x = 31
ROS = 62
Step-by-step explanation:
QOR + ROS = 90 degrees as indicated by the box
28+ 2x = 90
Subtract 28 from each side
2x = 90 -28
2x = 62
Divide by 2
2x/2 = 62/2
x = 31
ROS = 2x = 2*31 = 62
H^2 = 2 * (3 sqrt2)^2
= 2 * 18
= 36
hypotenuse = sqrt 36 = 6
