A: 168

Y: 18

T: 140

E: 7

P: 19

Step-by-step explanation:

I used order of operations / PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction), and plugged in the values for a, b, n, and m. For letter E, add and subtract the values first then divide, it's easier. That's all I got for now. I'll solve the rest and answer as soon as possible. :)

The number of solution the equation 4x - 5 (2x + 1) = 6x + 1 have is one.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

4x - 5 (2x + 1) = 6x + 1

4x - 10x - 5 = 6x + 1

-6x - 5 = 6x + 1

-5 - 1 = 6x + 6x

-6 = 12x

x = -6/12

x = -1/2

This means,

The equation has one solution.

Thus,

The equation has one solution.

Answer: it is 0

Step-by-step explanation:

[5.5+(-2.3)] + (-5.5+2.3)

We can multiple (-5.5+2.3) by -1 so that it equals the first expression

[5.5+(-2.3)] + (-1)[5.5+(-2.3)]

Then, we change the + to -

[5.5+(-2.3)] - [5.5+(-2.3)]

since we are subtracting the same value, the answer is 0.

Answer:

Step-by-step explanation:

7y+5z-2y+z

Group the two y and the two z together

7y-2y = 5y

5z+z= 6z

(a variable with out a number is = to 1)

so it would be  5y+6z

Answer: C. [tex]\sqrt{875[/tex]

Step-by-step explanation:

use Pythagorean theorem [tex]a^{2}+b^{2}=c^{2}[/tex]

a=5 c=30 solve for b

[tex]25+b^2=900[/tex]

subtract 25 from both sides to get [tex]b^2 =875[/tex]

then square both sides to get [tex]\sqrt{875[/tex] for the length of the other leg

Answer:

1. a. draw 5 boxes with 7ś in them and x=7

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

Step-by-step explanation:

1. the value of x is seven because 5x = 35 divide x on both sides is 7

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

We can divide both sides of the equation by 43 to solve for x:

90x / 43 - 47y / 43 = -49 / 43

x = -49/43

We can substitute this value for x back into either of the original equations to find y. Let's substitute it into the first equation:

-5x + 3y = -6

(-5 * -49/43) + 3y = -6

y = (-6 + 5 * 49/43) / 3

y = 17/43

The solution to the system of equations is (x, y) = (-49/43, 17/43).

To check our solution, we can substitute the values we found for x and y back into the original equations and see if they hold true.

In the first equation, -5x + 3y = -6, substituting the values we found for x and y gives us:

(-5 * -49/43) + (3 * 17/43) = -6

This simplifies to -6 = -6, which is true, so the solution holds for this equation.

In the second equation, 9x - 4y = 1, substituting the values we found for x and y gives us:

(9 * -49/43) - (4 * 17/43) = 1

This simplifies to -1 = -1, which is true, so the solution holds for this equation as well.

Therefore, the solution (x, y) = (-49/43, 17/43) is correct.

Answer:

a) The new balance in your checking account is -$12.58 - $30.72 = -$43.30.

b) After the bank charges a $25 fee for overdrafting, the balance in your checking account will be -$43.30 - $25 = -$68.30.

c) To bring your account balance back up to $0 after the fee, you will need to deposit $68.30.

Step-by-step explanation:

Answer:

First, you subtract the 30.72 from the -12.58 which is -43.03 which is therefore how much you have in your account. Then we subtract another 25 for the fee. -68.03 Is how much you have after paying the fee.

Therefore, to get to 0, you need to pay 68 dollars and 3 cents.
