Answer:
78.94
Step-by-step explanation:
It's the circle of life yeah yeah and it moves us all.
Let's have x be the number of children tickets and 2x will be the adults. Now we can set up the following equation:
5.4x+8.9(2x)=626.4
Expand this out:
5.4x+17.8x=626.4
Combine like terms:
23.2x=626.4
Divide both sides by 23.2 to get x=27
The answer is -7
The arrows both point toward the left side, and sine there are seven spaces the arrows are going through, you subtract 7 spaces and get -7
Hope that helps.
<span>Let number of experienced crew = X
Let number of novice crew = Y
Number of rooms experienced crew can prep = 6X
Number of rooms experienced crew can paint = 2X
Number of rooms novice crew can prep = 2Y
Number of rooms novice crew can paint = 2Y
Number of rooms to be prepped per week = 12
Number of rooms to be painted per week = 8
So, we have
Equation 1 - For Prepping
6X + 2Y = 12
Equation 2 - For Painting
2X + 2Y = 8 or 2Y = 8 - 2X
Replacing the value of 2Y from equation 2 in equation 1, we have
6X + (8 - 2X) = 12
Simplifying the equation we get
4X + 8 = 12
4X = 12 -8
4X = 4
X = 4/4
X = 1
Replacing the value of X in Equation 1, we get
6 * 1 + 2Y = 12
2Y = 12 - 6
2Y = 6
Y = 6/2
Y = 3
Total cost per week = 1 * 1000 + 3 * 750 = 1000 + 2250 = 3250
So, to optimize costs, John would need 1 experienced crew and 3 novice crews at a total cost of $3250 per week.</span>
Answer:
4 ft , 16 ft & 20 ft
Step-by-step explanation:
40 = x + 4x + 5x = 10x --> x = 4
