PEMDAS is the order of operations. Here’s how to solve this expression:

Expression: 15+14 ÷ 2-4•5

1.) Parentheses: there are no parentheses to
simply.
2.) Exponents: there are no exponents to
simply.
3.) Multiplication and Division: multiplication and division have an equal relationship meaning one operation doesn’t have a priority over the other. So, we work left to right as to what operation comes first.

In the expression 15+14 ÷ 2-4•5, we see that 14 ÷ 2 comes first because it’s to the left.

14 ÷ 2 = 7

15+(7)-4•5 after division, now we need to multiply.

-4•5 = -20

Therefore, 15+(7)-(20) is the simplification.

4.) Addition and Subtraction: addition and subtraction come after multiplication and division and also have an equal relationship. So again, we work left to right as to which operation comes first.

In the expression 15+7-20, 15+7 comes before 7-20.

15+7 = 22

So, (22)-20 after addition. Now we need to subtract.

22-20 = 2. That’s your answer!

The equations in this sytem were added to solve for x. What is the value of x?
son4ous [18]

<em><u>Question:</u></em>

The equations in this system were added to solve for x. What is the value of x? -2x+y=8 5x-y=-5 3x=3

Options:

x = negative 3

x = negative 1

x = 1

x = 3

<em><u>Answer:</u></em>

The value of x is 1

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

-2x + y = 8 ------- eqn 1

5x - y = -5 ------- eqn 2

The above equations are added to solve for "x"

Add eqn 1 and eqn 2

-2x + y + 5x - y = 8 - 5

Combine the like terms

-2x + 5x + y - y = 3

Add the like terms

3x + 0 = 3

3x = 3

Divide both sides of equation by 3

x = 1

Thus the value of x is 1

Please help im stuck on this question​
VARVARA [1.3K]

Answer:

(12,0)

Step-by-step explanation:

slope m=

\frac{54-36}{27-22} =\frac{18}{5}

y-36=\frac{18}{5}(x-22)\\\\5y-180=18x-396\\\\y=\frac{18x}{5} -\frac{46}{5}

0=\frac{10}{5}x-\frac{46}{5}\\\\x=\frac{216}{18}   =12

hope it helps...

have a great day
