Brianna's teacher asks her which of these three expressions are equivalent to each other.
Tema [17]

Answer:

<em>Briana's thinking is incorrect because the numbers are different when you substitute x with numbers other than 0.</em>

the two equations that are equivalent to each other are,

<u><em>5x+x−4 and 9x-3x-4</em></u>

Step-by-step explanation:

Expression A: 9x−3x−4

​Expression B: 12x−4

​Expression C: 5x+x−4

First I will substitute x for each of the equations.

9x-3x-4

when x equals: , then y equals:

1                        =        9(1)-3(1)-4= 2

2                       =         9(2)-3(2)-4=8

3                       =      9(3)-3(3)-4= 14

Now for 12x-4

when x equals: , then y equals:

1                        =        12(1)-4=  8

2                    =         12(2)-4= 20

3                       =      12(3)-4=  32

And for the final equation:

5x+x−4

when x equals: , then y equals:

1                        =        5(1)+(1)−4= 2

2                       =         5(2)+(2)−4 = 8

3                       =      5(3)+(3)−4=14

Based on this you can now see that the two equations that are equal are:

<u><em>5x+x−4 and 9x-3x-4</em></u>

Ruth uses healthy credit to finance $2,200 for a hearing aid how much would she have to pay each month to pay back the loan in e
REY [17]

Answer:

$183.3

Step-by-step explanation:

Ruth uses healthy credit to finance $2,200 for a hearing aid how much would she have to pay each month to pay back the loan in exactly 1 year

Ruth took a loan of $2,200

1 year = 12 months

Hence, the amount she would be paying monthly is calculated as:

$2,200/12 months

= $2,200/12

= $183.33333333

Approximately = $183.3

Therefore, Ruth would be paying $183.3 monthly.

You have been asked to build a scale model of your school out of toothpicks. Imagine your school is 30 feet tall. Your scale is
adelina 88 [10]

Alright, let's begin! We start with 37.8 and then divide it with..7.6! Now, we try to get the answer of that.

37.8 ÷ 7.6 = 4.973.

However, we need to bring it down to an estimate. It would then be 4.97. Although, we need to also see if our answer is correct.

4.97 × 7.6 = 37.7

There is more answers closer to the number but this should be the correct answer due to it being the answer of all the steps I used.

But wait! We need the round the answer to the nearest whole number. So, it would be 38.

So, overall, it will be 38 cotton swabs tall.

Hope this helps!

If you are needing any other help, tell me in the comments below this answer! If you want any contact tell me and I'd be glad to help.
