Step-by-step explanation:
-9 + 16/7 = ?
First, find out what 16/7 would make in decimal form, by dividing 16 by 7 (Use a calculator if needed)
16 / 7 = 2.3 (In estimation)
So, now you have ' -9 + 2.3 '
= -6.7
Answer:
Number of offices to be cleaned to cover the cost of equipment =15
Cost of equipment =$.315 Cost of supplies =$.4 Charge per office =$.25
Number of offices to be cleaned to cover the cost of equipment =x
Then -25x − 4x =315
21x =315
x=315
21=15
Number of offices to be cleaned to cover the cost of equipment =15
Answer:
B
Step-by-step explanation:
First, check to see which graph has a line going through the point (2,3). B and D are the only ones that have lines going through (2,3) (A comes close but it is not quite).
Next, you need to see which line would be parallel to the equation 3x-y=2. When two lines are parallel, they have the same slope. You have to turn that equation into point-slope formula (y=mx+b with m being the slope and b being the y-intercept). First, subtract 3x from both sides. You will then get -y=-3x+2. Then y needs to be alone (right now it has a -1 attached). Divide both sides by -1 to get y=3x-2. The number in front of the x is the slope, in this case, 3 or 3/1 (we do not care about the y-intercept, it will not help us in this problem since we are looking for a line parallel to this equation and so our line will not have the same y-intercept as this other equation). Since the line in parallel to that equation, we know that this line also has a slope of 3/1. Find the line between B and D that has a slope of 3/1, you get B (the line goes up 3 over 1).
Answer:
To solve the above riddle, you just need to think creatively and not take the question literally. The answer to the above riddle is, "Four kids get an apple and the fifth kid gets an apple still in the basket." This way, everyone gets an apple and the last apple still stays inside the basket.
