Answer:
x = 20
Step-by-step explanation:
Simplifying
1250 + 27.50x = 1400 + 20x
Solving
1250 + 27.50x = 1400 + 20x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20x' to each side of the equation.
1250 + 27.50x + -20x = 1400 + 20x + -20x
Combine like terms: 27.50x + -20x = 7.5x
1250 + 7.5x = 1400 + 20x + -20x
Combine like terms: 20x + -20x = 0
1250 + 7.5x = 1400 + 0
1250 + 7.5x = 1400
Add '-1250' to each side of the equation.
1250 + -1250 + 7.5x = 1400 + -1250
Combine like terms: 1250 + -1250 = 0
0 + 7.5x = 1400 + -1250
7.5x = 1400 + -1250
Combine like terms: 1400 + -1250 = 150
7.5x = 150
Divide each side by '7.5'.
x = 20
Simplifying
x = 20
It’s asking you to work out the median which you have to find the middle number for.
Answer:
g(x+4)= -8(x+4)+2
=-8x-32+2=-8x-30
g(x)+g(-2)=-8x+2+(-8(-2)+2)
=-8x+2+(16+2)
=-8x+20
a.=-8x-30
b.=-8x+20
Step 1: Let us first list down the given information. We are given 2 people enter the theater every one minute. Also, we need to have 70 people in the theater.
Step 2: Let us assume that x represents the number of minutes that must pass until there are 70 people in the theater.
Step 3: Since 2 people arrive per minute. Therefore, total number of people who arrive at the theater in x minutes can be expressed as .
Step 4: We can now frame a linear equation using the fact that there are 70 people in the theater in x minutes:
Step 5: In order to find the number of minutes, we will divide this equation by 2 on both the sides:
Therefore, 35 minutes must pass in order for 70 people to arrive at the theater.
