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!

Answer: -4x - y = -50 (second option)

Step-by-step explanation: The only way lines won't intersect is if they're parallel. Parallel lines have the same slope --> the line must have a slope of -4x.

Option 1:

  • y = 4x - 200 (add 4x to both sides)
  • <em>Different slope.</em>

Option 2:

  • -y = 4x - 50 (add 4x to both sides)
  • y = -4x + 50 (divide by -1)
  • <em>Same slope.</em>

Option 3:

  • -y = -4x - 200 (subtract 4x from both sides)
  • y = 4x + 200 (divide by -1)
  • <em>Different slope.</em>

Option 4:

  • -y = -4x - 50 (subtract 4x from both sides)
  • y = 4x + 50 (divide by -1)
  • <em>Different slope.</em>

The length of a rectangular garden is 30 yards more than the width. The perimeter is 300 yards. Find the length and width
Delicious77 [7]

Answer:

Length is 90yards and width is 60yards

Step-by-step explanation:

Perimeter= 2( length+width)

let the width be x

then the length will be 30 + x

300 = 2(30+x+x)

150 = 30 + 2x

120= 2x

x = 120/2

x = 60 yards

length= 30+x

= 30 + 60

= 90yards
