<span>x – y = 30, when y = 15
x - 15 = 30
x = 30 + 15
x = 45
answer: </span><span>when y = 15, x = 45</span>

Here, we have to collect like terms.
_________________________________
▪️What do you mean by like terms ?
⇒Like terms are those which have the same base. While adding or subtracting like terms, we should add or subtract the coefficients of like terms.

Answer: 50
Step-by-step explanation:
From the question, we are informed that 1/3 of gym members say they spent 5 hours per week at the gym.
Assuming there are 150 people working out at the gym, the number of people that'll most likely spend 5 hours at the gym this week will be calculated by multiplying 1/3 by 150. This will be:
= 1/3 × 150
= 50 people

I think it is wrong and the price is $55.
Answer:
x1=-3+i*sqrt(13)
x2=-3-i*sqrt(13)
Step-by-step explanation:
x^2 +6x=-22
x^2 +6x+22=0 (Quadratic equation)
a=1, b=6, c=22
x1=(-b+sqrt(b^2-4ac)) /2a
x1=(-6+sqrt(6^2 -4*1*22))/2*1
x1=(-6+sqrt(36-88))/2
x1=(-6+sqrt(-52))/2
x1=(-6+sqrt(52i^2))/2...... i^2=-1
x1=(-6+sqrt (4*13i^2))/2
x1=(-6+2i*sqrt(13))/2
x1=-3+i*sqrt(13)
x2=(-b-sqrt(b^2-4ac)) /2a
x2=-3-i*sqrt(13)
