The seamstress would have to sew 15 pockets for $60. Just divide 60.00 by 4.
Answer:
8m-5
Step-by-step explanation:
Lets write this out in an equation.The plus means addition and the minus means subtraction.
6m+2m-5
Since there is two things with the same variable we can combine them.
8m-5
That is as simple as it gets.
A number (we don’t know the number so I’ll use X) plus five. So we can start the equation of with X+5 then divided by 3=7 so X+5➗3=7 so to solve what X is we can just go in reverse. 7 TIMES 3= 21-5=16 so X=16
Answer:
It is not a function.
Step-by-step explanation:
This is what we call a mapping;
Functions do not give multiple output values for a given input value;
As we can see, the input 2 produces an output of 20 and 40, therefore we can tell this is not a function.
One car travels at a speed of 75 kilometers per hour and the other car travels at a speed of 105 kilometers per hour.
Since both the cars are travelling towards each other their combined speed will be: 75+105=180 km/h.
Now, since the distance between the cars to start with is 540 km. Therefore, the time taken before the cars collide is:
hours.
Now, the speed of the canary is 100 km/h.
Therefore, the Canary flies flies for (100 km/h)x(3 hours) = 300 km before the cars collide.
