y- (-250) = 50 (x-(-5) )

Answers

Answer:

y = 50x

x = y ÷ 50

Step-by-step explanation:

y - (-250) = 50(x - (-5))

y + 250 = 50(x + 5)

y + 250 = 50x + 250

y = 50x + 250 - 250

y = 50x

x = y ÷ 50

Answer:

y-(-250)=50(x-(-5))

y+250=50x5

y+250=250

In a race, 41 out of the 50 bicyclists finished in less than 38 minutes. What percent of bicyclists finished the race in less than 38 minutes? Write an equivalent fraction to find the percent. ​

Answers

for left put 2 on each
On the box over 100 put 82, and put 82 in the box on the right
to find the percent, you will double everything because you only have 50 as the base and doubled its 100. 41 times 2 it’s equal to 82 so 82% of the bicyclists finished in less than 38 minutes. As a fraction it would be 41 over 50.

Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2

Answers

Answer:

.

Step-by-step explanation:

well let’s think about it this way. we can take the like numbers and add or subtract them right? so let’s think of all the like numbers.

3x, -2x, and 2x are like numbers

2y, and 2y are like numbers

2 and 2 are like numbers.

now that we have all of the like numbers down, lets start with the first set of numbers before the = sign.

3x+ 2y- 2x+ 2

well since we have 2 like numbers in there, let’s add those, so we have 3x + 2x, which that would give us 5x. since we have nothing else in that, out expression for that one would be 5x + 2y + 2. next one we have:

3x - 2x+ 2y+ 2

we have like factors in this one too. since we have a subtraction sign in between them, we have to take 3x - 2x which gives us 1x or x. which that expression would be (x + 2y + 2). if you have to add the expressions together the whole thing would be (6x + 4y + 4).

if the (-) is supposed to be a negative, then the problems would be, x + 2y+ 2; x + 2y + 2. which the ending would be 2x + 4y + 4. hope this helps. if i’m wrong someon correct me.
