Answer:

B

Step-by-step explanation:

first make each equation 'y='.

then if you times each x value by each other it has to equal '-1'.

so for B, itll be y=1/3x-11/3 and y=-3x+23.

1/3 x -3 = -1

Help me solve this problem.
irina [24]

We can write an equation to resemble the problem.

1160 = 170 + 50x

x equals the number of boxes he is carrying.

Solve for x.

1160 = 170 + 50x

990 = 50x

19.8 = x

We can't round up because that will be to much weight. So, we are going to round down.

19.8 -> 19

Therefore, the answer is 19.

Best of Luck!

So an example


least common multipule is like what is the smallest number both will fit into


example, 6 and 10, least common multilule is 30 because 6*5=30 and 3*10=30


so 3 and 4

factor each

3=3

4=2*2

so we have to have 2*2*3 which is 12


12 is least common multiplule
