Answer 1
Answer: You will need to set up your table of values for each person.

Let x represent the months, and y for the amount of money.

For Carissa:                             For Louann:
x = y                                         x = y
--   --                                         --    --
0    $250                                 0   $1230
1    $330                                   1   $1170
2    $410                                  2   $1110
3    $490                                 3   $1050
4    $570                                 4    $990
5    $650                                 5    $930
6    $730                                 6    $870
7    $810                                 7    $810

You could also do the equation:
80x + 250 = -60x + 1250
where you will get x=7.
Then substitute 7 to the x's in the equation which will give you $810 for each.

The answer is: It will take 7 months. Then, they will both have $810 in their accounts.
Answer 2
Answer:
This exercise is trying to get you to write an equation
that describes what's going on.

Carissa has $250 today, and she adds $80 to it each month.
In  'm'  months from now, she'll have  80m  more than $250.

                C (for Carissa)  =  250 + 80m

Louann has $1230 today, and she takes out $60 each month.
In  'm'  months from now, she'll have  60m  less than $1230.

               L (for Louann)  =  1230 - 60m

Carissa has less money today, but it's growing $80 every month.
Louann has more money today, but it's losing $60 every month.
Eventually, they'll both have the same amount.
The question is:  When and how much ?

Well, when they both have the same amount, then  C = L .

                                         250 + 80m  =  1230 - 60m

That's the end of the hard part of this problem ... writing
the equation. The rest is easy, and I'm sure you'd have
no trouble solving it.  But since I'm on a roll, and I'm
going to take your 5 points, I might as well keep going:

                                           250 + 80m  =  1230 - 60m

Subtract 250 from each side:    80m  =    980 - 60m

Add  60m  to each side:            140m  =  980

Divide each side by  140 :                m  =  7

This is telling us that after 7 months, Carissa and Louann will both
have the same amount of money in their accounts.

The problem also asks us how much that is.  So let's find the
amount for both of them, just to check our work and make sure
they're both the same:

Carissa:   250 today + (7 months x $80/month) = 250+560 = $810 .

Louann:  1230 today - (7 months x $60/month) = 1230-420 = $810 

                                                                                                       yay !

Need help with problem can you help 5x+3y=22 y=2x

Answers

if y = 2x, let's replace it on  5x+3y=22

5x+3*(2x)=22

5x+6x=22

11x=22

\boxed{\boxed{x=2}}

Therefore

y=2x

y=2*2

\boxed{\boxed{y=4}}
5x+3y=22    y=2x
5x+3(2x)=22
5x+6x=22
11x=22
x=2

y=2(2)
y=4
x=2 y=4

ΔXYZ is translated 4 units up and 3 units left to yield ΔX′Y′Z′. What is the distance between any two corresponding points on ΔXYZ and ΔX′Y′Z′ ?25 units

7 units

5 units

7√ units

Answers

By translating triangle ABC 4 units up and 3 units left to form triangle A'B'C' means that the line joining each of the corresponding points represents the hypothenus of a right triangle with legs 4 units and 3 unit. To find the length of each corresponding points, we use the prthagoras theorem which states that the square of the length of the pythagoras of a right triangle is equal to the sum of the squares of the lenght of other legs. i.e. the square of the required distance = 4^2 + 3^2 = 16 + 9 = 25 Therefore, the distance of eachcorresponding side is given by the square root of 25 = 5.

Which of the following is an equivalent simplified expression for 2(4x + 7) – 3(2x – 4) ?A. x + 2
B. 2x + 2
C. 2x + 26
D. 3x + 10
E. 3x + 11
Can anyone explain this one for me?

Answers

The expression 2 × (4x + 7) – 3 × (2x – 4) in the equivalent simplified form will be 2x + 26. Then the correct option is C.

What is an equivalent expression?

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ 2 × (4x + 7) – 3 × (2x – 4)

Simplify the expression, then we have

⇒ 2 × (4x + 7) – 3 × (2x – 4)

⇒ 8x + 14 – 6x + 12

⇒ 2x + 26

The expression 2 × (4x + 7) – 3 × (2x – 4) in the equivalent simplified form will be 2x + 26. Then the correct option is C.
