Each hour,
x makes b/6 bearings
y makes b/4 bearings
z makes b/3 bearings

Together, each hour, x, y and z together make
b/6+b/4+b/3=b(1/6+1/4+1/3)=b(2/12+3/12+4/12)=b(3/4)=3b/4 bearings.

Time to make b bearings =
b/(3b/4)=4/3 hours = 1 hour 20 minutes.

A rectangle's perimeter and its area have the same numerical value. The width of the rectangle is 3 units. What is
aleksklad [387]

Answer:

l = 6.00

Step-by-step explanation:

So A = l x w and P = 2l + 2w, they say they are equal to l (w) = 2l + 2w and we know that w = 3 so

3l = 2l + 2(3), so l = 6.

Rhea sold 6 boxes of blueberry muffins and 8 boxes of corn muffins at the bake sale. Each box contained 18 muffins. The muffins
Elenna [48]
6 boxes of blueberry muffins and 8 boxes of corn muffins

Since we know that each box has 18 muffins, we can multiply both 6 and 8 to determine the amount of muffins present

6 • 18 = 108 blueberry muffins
8 • 18 = 144 corn muffins

To determine the price, you multiply each type of muffin by 0.50 as each muffin is worth $0.50

108 • 0.50 = 54
144 • 0.50 = 72

You add these two together to get the price

54 + 72 = $126

If you explain what the estimate is, if I didn’t answer that along the way, I can help answer it for you.

pantera1 [17]

y -3 = 2(x-4)

Use distributive property on the right side:

y - 3 = 2x -8

Add 3 to both sides:

y = 2x -5

The answer is A.
