Answer:
<h2>✓ Simplifying Expressions</h2>
<h3>Solution:</h3>
- Adding the numerical coefficient with the terms that have the same variables. Meaning they are like terms. Adding the base and then copy the variables.
<h3>> Therefore, the answer is 7y.</h3>
45 × 13 = 585
Which is exactly how much he'd need to pay back his sister and buy the bike. So, it would take him 13 weeks.
Answer:

Answer:
x=4.0625 cm
Step-by-step explanation:
The Pythagorean theorem states that the square of the hypotenuse of a right triangle equals the sum of the squares of the two legs.
Not knowing which is the hypotenuse, lets assume that (x+5)cm is the hypotenuse:
(x+5)^2= 9^2+(x-3)^2
(x^2+10x+25)=81+(x^2-6x+9)
x^2+10x+25=81+x^2-6x+9
16x=65
x=4.0625
Checking:
(4.0625+5)^2=9^2+(4.0625-3)^2
82.1289=82.1289
