In the second and third line, where 3x was taken off both sides. On the left -3x-3x should have given -6x.
3x should have been added to both sides in order to cancel out the -3x

PLS HELP NOBODY WILL HELP ME JUST SPAM ANSWERS I WANNA CRY JUST PLS ANYONE? ILL DEFINETLY GIVE BRAINLIEST : (
Vikentia [17]

Answer:

7(left answer), 3(top left answer), and 10(top right answer)

Step-by-step explanation:

So what are two things that go into 21?

  1. 21 and 1
  2. 7 and 3

Out of those two, which is a factor of 70? Right off the bat we know 7 is.

THis isnt the greatest factor of 70, but it is for both 21 and 7, so now we know the left answer for hieght is 7.

Now 3 must be the top left answer, because you must make 21 with 7. 7 Goes into 21 3 times, so it has to be 3. So now we know that the top left anhswer is 3.

Finally we have our top right answer. We already know that the height is 7, now we need to find the width. All we have to do is divide 70 by the 7 heigh, and we will find our width:

70/7

=

10

So now we know that the top right answer is 10.

<u>Sorry that you couldnt get a real answer from people, I hope this is in time to help! </u>

Cameron earn's $7 per hour at her after school job. The total amount of her paycheck varies directly with the amount of time she
polet [3.4K]

Answer:

Proportionality equation: y=7kx

Linear equation: y=7x

Step-by-step explanation:

So the amount that Cameron earns = 7/hr

Hours = x

And total earned amount = y

So we can form an equation from this for the total amount:

y=7x

But the question asks us for a proportionality equation so:

Proportionality constant = k

So we get the equation:

y=7*k*x

Four friends own a car wash. The total profit in the first month was $438$438. In two months, each of the friends had made a pro
weeeeeb [17]

Answer:

$298

Explanation:

There are 4 friends, each of whom splits the profit equally.  Since they each had a total of $184 at the end of the second month, that means the car wash had made

184(4) = 736 by the end of the second month.

Now we subtract the amount of profit in the first month:

736 - 438 = 298
