Answer:

10

Step-by-step explanation:

So because AC is intersected at the middle, or the midpoint, being E, you can say that both sides of AC; AE and EC, are equal to each other. You can make 4x-3=3x-1 and combine like terms to get X on one side by itself. First, you want to subtract 3x from both sides to move the x from left side and only have it on the right. You should x-3=-1. Then, you want to remove the -3 from the left side and bring it to the right to have x by itself. To cancel the -3 on the left side you have to add 3 on both sides. You should have x=2. Now that you have x, you can plug it into both AE and EC, then add them together. You should have 5 for AE and 5 for EC, and adding them up makes 10. Hope I could help :)

Mason opens a savings account by making a $165. 85 deposit. Every week, he deposits another $20. 50 in the account. Write an exp
Lana71 [14]

Algebraic expression is the expression which consists the unknown variables, constant and coefficients of variables. The expression that shows the amount of money that will be in the account <em>x</em><em> </em>weeks after Mason opens it is,

f(x)=165.85+20.5x

Hence the option 4 is the correct option.

Given information-

Mason opens a savings account by making a $165.85.

The money deposit by Mason every week is $20.50.

<h3>Algebraic expression-</h3>

Algebraic expression is the expression which consists the unknown variables, constant and coefficients of variables.

The algebraic expressions use to represent the set of condition of a problem in a mathematical way.

As the initial amount deposit by Mason is $165.85. Thus this amount is fixed and not going to change with the further deposit.

The money  deposit by Mason every week is $20.50. This money is not fixed and increased by $20.50 every week. Thus this is a variable amount.

Therefore the algebraic expression for the given condition can be given as,

f(x)=165.85+20.5x

Thus the expression that shows the amount of money that will be in the account <em>x</em><em> </em>weeks after Mason opens it is,

f(x)=165.85+20.5x

Hence the option 4 is the correct option.

The graph below shows the balance in Steven's savings account as a function of time. Please Helpp
zhuklara [117]

Answer:

Steven starts with an account balance of $300

And with each passing month his balance increases by $150

Step-by-step explanation:

300 is you're start value

On the graph you can see that Feb. 1 hits the line on the graph between $300 and $600. You want to find half of $300, So you divide 300 by 2, And that give you 150.

Then with you can add 150 to 300 to give you 450. Then add 150 to 450 to give you 600. And repeat the process.

Hope This Helps :)

Ryan planted flowers in a rectangular garden. The width of the garden is left parenthesis x minus 5 right parenthesis(x−5) feet
Nookie1986 [14]

。☆✼★ ━━━━━━━━━━━━━━  ☾  ━━━━━━━━━━━━━━ ★✼☆。

- The equation :

Area = length x width

- Substitute the values in :

Area = (x - 5)(x - 5 + 22)

(Note : the 'x' is for the algebraic expression x in the example above)

- Now you have to simplify the second parenthesis:

Area = (x - 5)(x + 17)

- Now expand :

Area = x^2 + 17x - 5x - 85

- Simplify by collecting like terms :

Area = x^2 + 12x - 85

(Note : x^2 means x squared)

Now you have your answer as:

x^2 + 12x - 85 feet^2

Have A Nice Day ❤
