Step-by-step explanation:
Answer:
Alisa practiced for 240 minutes (4 hours). In total, they practiced for 288 minutes (4.8 hours).
Step-by-step explanation:
If James practiced for 48, and Alisa practiced 5 times as long, then we would multiply 48 by 5 (240 minutes).
If we want to find how many minutes in total they practiced, then we would add 240 minutes (Alisa's practice time) and 48 minutes (James' practice time) together, which would equal 288 minutes (4.8 hours).
Equation: y=48+x
C must be 80° to make the triangle angles add to 180°. The corresponding angles of similar triangles are congruent. So
Answer: y=80°
Answer:
{x | x R, x > -5}
Step-by-step explanation:
Given:
Add 5 both sides, we get
Therefore, the solution is 
where, x is a real number.
So, {x | x R, x > -5} is the correct answer.
