A = -6

order of operations does division first, but you have to know that you must add -1 to 9 in order to get 8. Therefore, you must have a negative number over 6 and it has to be -6 in order for that negative number to be -1

<span>9+a/6=8
Subtract 9 from both sides
a/6= -1
Multiply 6 on both sides so that the only thing remaining on the left side is the variable a.

A cement walk 3 ft wide is placed around the outside of a rectangular garden plot that is 20ft by 30ft. Find the cost of the wal
Inessa05 [86]

Let us calculate the area of the walk.

Since the width of the walk is 3 feet, and the walk will be placed all the 4 sides,

Length of the plot including walk = 20 + (2 × 3) = 20 + 6 = 26 feet.

Breadth of the plot including walk = 30 + (2 × 3) = 36 feet.

Area of the plot including walk = 26 × 36 square feet.

Area of the plot = 20 × 30 square feet.

Area of the walk = (26 × 36) - (20 × 30)

= 936 - 600

= 336 square feet.

= \frac{336}{3(3)} square yards

= 37.3 square yards

Cost of the walk per square yard = $12.25.

Therefore, total cost of the walk = 12.25 × 37.3 = $456.92.

marysya [2.9K]

Answer:

  • equation: (7x-4) +19 +(10x+3) = 52
  • x = 2
  • red: 10
  • blue: 19
  • yellow: 23

Step-by-step explanation:

The equation is based on the relation that the perimeter is equal to the sum of the side lengths.

  P = red + blue + yellow

  52 = (7x -4) +(19) +(10x +3)

  52 = 17x +18 . . . . . . . . . . . . . . simplify

  34 = 17x . . . . . . . . . . . . . subtract 18

  2 = x . . . . . . . . . . . . divide by 17

__

  red = 7(2) -4 = 10

  blue = 19

  yellow = 10(2) +3 = 23

Miss white wants to buy 5 value meals at mels dinner what is a reasonable total for he purchase
bagirrra123 [75]

Answer:

Step-by-step explanation:

Here you're being asked to recall your own experience in paying for "value meals."  How much have you paid per meal?

If each meal costs $6.50, then 5 would cost $13.00 before tax, and

(1.07)(5)($13.00), or $69.55 total.

Note that there's not just one possible total cost, and that we don't know much about this situation but must insert reasonable values, such as a $6.50 per meal unit cost and a 7% tax rate.
