Answer: b & c

Step-by-step explanation:

first i found how many hours tonya works in one week which was 20. i got that by dividing 60 by 3. then that set me up for finding the answer to the other problems as well. 60+20=80 so a wouldn’t have worked. 5x5 is 25 and she only worked 20 hours a week. and she would’ve worked 320 hours in 16 weeks, not 240. hope this helps!! :)

Answer:

B and C

Step-by-step explanation:

This problem is pretty simple if you know how to do some multiplication. First, we should figure out how many hours she works per week. You can figure this out by dividing 60 by 3. This gets us 20.

Now that we know how many hours she works each week, we can figure out the rest of the problems.

A is incorrect because 4 x 20 =80.

B is correct because 7 x 20 is 140.

C is correct because we did this problem earlier to solve the others.

D is in correct because 5 x 5 = 25, which does not equal 20.

E is incorrect because 16 x 20 =   320

Sorry if I'm not very good at this, as this is my first time solving someone's question.

nalin [4]

Answer:

The dimensions of rectangular fence are 14 feet and 20 feet.

Step-by-step explanation:

We are given the following in the question:

Length of rectangular fence = 14 feet

Width of fence = (14+x) feet

Area of rectangular field = 280 square feet

Area of rectangular field =

A= \text{Length}\times \text{Width}

Putting the values, we get,

280 = 14(14+x)\\\\14 + x = \dfrac{280}{14}\\\\14 + x = 20\\x =20-14\\x = 6

Thus, the dimensions of rectangular fence are 14 feet and 20 feet.

In other words, no two or more ordered pairs should have the same first coordinate.

For options A, the first coordinate repeated.
