It costs $5.08 for 4 pounds of gummy candy in bulk. How much would it cost to buy 17 pounds?
Daniel [21]

Answer:

$21.59

Step-by-step explanation:

Basically how I did it was to multiply 5.08 by 4, because that would be the cost of 16 bags and then I divided 5.08 by 4 to see how much one bag would cost. One bag costs 1.27. After I've got the answer, I added 1.27 to 20.32 and got $21.59.

A rectangle is 6 inches longer than it is wide. The perimeter of the rectangle is 44 inches.Write and solve an equation for the
Nataly_w [17]

Answer:

Length is 14 in

Width is 8 in

Step-by-step explanation:

<u>Given:</u>

  • Length = l
  • Width = w
  • Perimeter = P = 44 in
<h3>Solution</h3>

<u>Equations as per given:</u>

  • l - w = 6
  • P= 2(l+w) = 44 ⇒ l +w = 22

<u>Adding up the two equations:</u>

  • l - w  + l +w = 6 + 22
  • 2l = 28
  • l = 28/2
  • l = 14 in

<u>Then finding the value of w:</u>

  • w = l -6
  • w = 14 - 6
  • w = 8 in

<u>Answer:</u> The length of the rectangle is 14 inches and width is 8 inches

Hello my name is lay lay today I am going to ask people this question if you answer this question you are my social studies part
ankoles [38]

Answer:

ok so regrouping is when the top number of a equation is like for EXAMPLE 3 minus 6 ok so 3 is lower than six so the number on the left side you cross that out and you add it to the number that was on top which would make it 13 in this case so 13 minus six is 7 and that’s regrouping

Help me please by solving and showing the steps:)
Lorico [155]

Answer:

-\frac{3\sqrt[3]{t} }{2}

Step-by-step explanation:

1: Write g(t) as y, resulting in y=-\frac{8}{27}t^3

2: Interchange the variables y and t, resulting in t=-\frac{8}{27}y^3

3: Multiply both sides by 27, resulting in 27t=-8y^3

4: Divide both sides by -8, resulting in -\frac{27t}{8}=y^3

5: Find the cube root of both sides, resulting in \sqrt[3]{-\frac{27t}{8} }=y

6: Apply a radical rule, resulting in -\sqrt[3]{\frac{27t}{8} } =y

7: Apply another radical rule, resulting in -\frac{\sqrt[3]{27t} }{\sqrt[3]{8} } =y

8: Simplify the denominator, resulting in  -\frac{\sqrt[3]{27t} }{2} =y

9: Apply yet another radical rule, resulting in -\frac{\sqrt[3]{27}\sqrt[3]{t}   }{2} =y

10: Simplify \sqrt[3]{27}, resulting in -\frac{3\sqrt[3]{t}   }{2} =y
