79.50-45 = 35.50 so she spent 35 dollars and 50 cents on jeans

The jeans would cost = $79.50 - $45.00 = $34.50

To check whether we got it right we would do $34.50 + $45.00 = $79.50.

Hope this helps.

Which expression is equivalent to 5^3?

AleksAgata [21]

Answer:

C and D

Step-by-step explanation:

5^3 - 5^0 = 125 - 1 = 124, so it's not A

5^12 / 5^4 = 5^(12-4) = 5^8, so it's not B

5^7 * 5^-4 = 5^(7+(-4)) = 5^3, so it can be C

5^0 * 5^3 = 5^(0+3) = 5^3, so it can be D

5 + 5^2 = 5 + 25 = 30, so it can't be E

QUICK!! 18x^2+21x-60=0 pls give me the steps as well

Anton [14]

Answer:

$x2 = \frac{4}{3}$

Step-by-step explanation:

$18 {x}^{2} + 21x - 60 = 0$

Divide both sides of the equation by 3

$6 {x}^{2} + 7x - 20 = 0$

Write 7x as a difference

$6 {x}^{2} + 15x - 8x - 20 = 0$

Factor out 3x from the expression

$3x(2x + 5) - 8x - 20 = 0$

Factor out -4 from the expression

$3x(2x + 5) - 4(2x + 5) = 0$

Factor out 2x + 5 from the expression

$(2x + 5)(3x - 4) = 0$

When the product of factors equals 0 , at least one factor is 0

$2x + 5 = 0$

$3x - 4 = 0$

Solve the equation for X

$2x + 5 = 0$

Move constant to R.H.S and change its sign

$2x = 0 - 5$

Calculate the difference

$2x = - 5$

Divide both sides of the equation by 2

$\frac{2x}{2} = \frac{ - 5}{2}$

Calculate

$x 1= - \frac{5}{2}$

Again,

$3x - 4 = 0$

Move constant to RHS and change its sign

$3x = 0 + 4$

Calculate the sum

$3x = 4$

divide both sides of the equation by 3

$\frac{3x}{3} = \frac{4}{3}$

Calculate

$x 2= \frac{4}{3}$

Hope this helps..

Best regards!!

Please can someone help me work out the missing length

Otrada [13]

Vol=area x Height

length= 3
breadth= X
Height = 2

area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so

42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7

so the missing length is 7cm
