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:
63.2
Step-by-step explanation:
So, we can break this shape into 2 shapes. A trapezoid and a rectangle.
For the trapezoid, we can do the formula.
((2.8 + 7.2)4)/2 = 20
Next, we can do the rectangle.
6 x 7.2 = 43.2
Now we can add them up and get our final answer.
43.2 + 20 = 63.2
Answer:
x = -11
m<B = -43
m<C = -22
Step-by-step explanation:
To solve for <em>x</em>, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.
I hope this is correct and helps!
Answer:
Bobby is correct
Step-by-step explanation:
Acute angles are classified as angles with a measurement of greater than 0° but less than 90°. If you add two acute angles, each as large as possible, the total will be less than 180 degrees.
