Step-by-step explanation:

Given that:

5(9 - x) + 3 = 23

Multiply the number outside of the bracket with numbers in the bracket on LHS.

⇛45 - 5x + 3 = 23

Shift constants from LHS to RHS, changing it's sign.

⇛-5x = 23 - 45 - 3

⇛-5x = 23 - 42

⇛-5x = -19

Shift the number 5 from LHS to RHS.

⇛x = -19/-5

Therefore, x = 19/5

Please let me know if you have any other questions.

$\qquad\huge\underline{\boxed{\sf Answer}}$

$\sf\longmapsto 5( - x) + 3 = 23$

$\sf\longmapsto - 5 + 3 = 23$

$\sf\longmapsto - 5x + 3 = 23 - 3$

$\sf\longmapsto - 5x = 20$

$\sf\longmapsto x = \frac{20}{5}$

$\sf\longmapsto x = - 4$

The system of equations above is graphed below. Find the solution to the system.

Oksana_A [137]

Option D: $x=3,y=-2$ is the solution to the system of equations.

Explanation:

Given that the equations are $4x+y=10$ and $2x+y=4$

We need to determine the solution of the system of equations.

The solution can be determined by solving the two equations.

Let us solve the system of equations using substitution method.

Consider the equation $4x+y=10$ , the value of y is given by

$y=10-4x$

Substituting the value of $y=10-4x$ in the equation $2x+y=4$ , we get,

$2x+(10-4x)=4$

Simplifying, we get,

$2x+10-4x=4$

$-2x+10=4$

$-2x=-6$

$x=3$

Substituting the value of $x=3$ in $4x+y=10$ , we get,

$4(3)+y=10$

$12+y=10$

$y=-2$

Thus, the solution to the system of equations is $x=3,y=-2$

Hence, Option D is the correct answer.

A department store is having a clothing sale. If a $35.00 pair of pants has a discount tag of 20% off, what is the sale price?

givi [52]

Answer:

$28.00

Step-by-step explanation:

You start with 35.00.

Now 10% of this is 3.5.

Multiply by 2 because it's 20%.

You get 7, so 7 is 20% of 35.00.

35.00 minus 7 is 28.00.

The pair of pants will be 28.00 dollars!
