Answer:
multiply 10 with the value given for x and add 2 to the result
-22.6667 ( or -22 2/3)
-4 * 5.6667 or -4 * 5 2/3 = -22.6667
Answer:
14 installatons
42 service calls
Step-by-step explanation:
Let x = no. of new installations
y = no. of service calls
(1) x + y = 56 (2) 450x + 75y = 9450
y = 56 - x 450x + 75(56 - x) = 9450
450x + 4200 - 75x = 9450
375x = 5250
x = 14 installatons
y = 56 - 14 = 42 service calls
Answer:
A. Three points
Step-by-step explanation:
Tangent circles will intersect at the one point of tangency.
Circles that cross each other will intersect in two points.
Circles that are coincident will intersect in infinitely many points.
It is not possible for two circles to intersect in exactly 3 points.
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.
