Can someone please help :(

Answer:

13 quarters and 21 nickels

Step-by-step explanation:

In this problem, a random person has $4.30 in his/her piggy bank. That is only nickels (0.05) and quarters (0.25). There are 8 more nickels than quarters. With that info, I can use the equation 0.25x + 0.05(x + 8) = 4.3 to figure out how many nickels and quarters there are.

0.25x + 0.05(x + 8) = 4.3 (Use the distributive property to multiply 0.05 by x and 8)

0.25x + 0.05x + 0.4 = 4.3 (Add 0.25x to 0.05x to get 0.3x)

0.3x + 0.4 = 4.3 (Subtract 0.4 from both sides)

0.3x = 4.3 - 0.4 (Subtract 0.4 from 4.3)

0.3x = 3.9 (Divide both sides by 0.3)

x = 3.9/0.3 (Divide 3.9 by 0.3)

x = 13

Knowing that there are 8 more nickels than quarters, I can degree there are 13 quarters and 21 nickels.

Substitute x for 13 in the equation to see if this is true.

0.25(13) + 0.05(13 + 8) = 4.3

3.25 + 0.05(21) = 4.3

3.25 + 1.05 = 4.3

4.3 = 4.3

So, x is 13.

There are 13 quarters and 21 nickels do we have.

Two or more expressions with an Equal sign is called as Equation.

Given,

$4.30 in your piggy bank with only nickels and quarters. You have 8 more nickels than quarters

0.25x + 0.05(x + 8) = 4.3

Apply distributive property

0.25x + 0.05x + 0.4 = 4.3

0.3x + 0.4 = 4.3

Subtract 0.4 from both sides

0.3x = 4.3 - 0.4

0.3x = 3.9

Divide both sides by 0.3

x = 3.9/0.3

x = 13

Hence, there are 13 quarters and 21 nickels we have.

Answer:

So you can cancel out the 16. See, the -16 is negative, and if we add +16 to it, then it cancels out and is 0. That way, you have x=1.

Step-by-step explanation:

-16x+x=-15

+16x      +16

   0+x=1

       x=1

Answer:

62%

Step-by-step explanation:

This one's easy to solve as a percentage because the total number was 100 to begin with. Simply divide the number of employed students by the total amount of students, 62/100, which gets 0.62, or 62%.

Answer:

2

Step-by-step explanation:

To find the scale factor of a dilation, we first find two corresponding sides. For example, the leftmost side of the black shape corresponds with the leftmost side of the blue shape. The side on the black shape measures 2 units while the side on the blue shape measures 4 units.

Now, we divide the length of the side taken from the figure by the length of the side taken from the original shape.

4/2=2

Therefore, the scale factor of the dilation is 2.

Step-by-step explanation:

For n laps, the length Keenan swims in the rec center pool is ...

  118 + 41n

and the length he swims in the gym pool is ...

  154 +32n

These are equal length for equal numbers of laps, so we have ...

  118 + 41n = 154 + 32n

  9n = 36 . . . . . . . . . . . . . subtract 32n+118

  n = 4 . . . . . . . . divide by 9

Then the length of Keenan's workout is ...

  118 +41(4) = 282 . . . . yards

It will take 4 laps to make the workout total 282 yards in each pool.

Answer:

x = 26

Step-by-step explanation:

If angle a and b are congruent, then set 68 and 4x + 8 together to equal to 180 on the right side.  Combine 68 and 8 together to get 76.  Then, subtract 76 on both sides to get 104 on the right side.  Divide that number by 4 to get your x-value which is 26.

Answer:

58 yards^2

Step-by-step explanation:

You want to break this irregular shape into simple shapes. You can make a rectangle with the sides of 4 and 6 yards, whose are is 24 yards^2.

Then you can do the rectangle on the opposite side, whose sides are 4 and 6 yards, whose are is 24 yards^2 again.

Then the final rectangle has the sides of 5 and   2 yards, whose area is 10 yards^2.

If you add it all up, you will get 58 yards^2.

Step-by-step explanation:

Answer: 110

Explanation: all 3 angles have to add up to 180.

Both the right and left angles are the same and since the left angle is 35 degrees we can safely conclude the right angle is as well, so all you have to do is is both of the 35 degree angles together which gives you 70, then subtract it from 180. 180-70=110 so that is the angle of 1. and since the bottom and top are the same the angle of 4 is also 110

Answer:

Step-by-step explanation:

1) 97 + x = 64 + 27          {Exterior angle property}

    97 + x = 91

            x = 91 - 97

          x = -6

2) 4x + 17 + 80 + x + 23 = 180   {Angle sum property of triangle}

 4x + x + 17 +80 + 23 = 180

                 5x + 140   = 180

                             5x = 180 - 140

                              5x = 40

                                 x = 40/5

                                x = 8

Answer:

Distance between the two points

AB = √52 = 7.2111

Step-by-step explanation:

Explanation:-

Given points are (-1,-2) and (5,2)

Distance formula

                 [tex]= \sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1})^{2} }[/tex]

                [tex]= \sqrt{(5-(-1) )^{2} +(2 -(-2))^{2} }[/tex]

               [tex]= \sqrt{(6 )^{2} +(4)^{2} }[/tex]

              =   √36+16

             =√52

            = 7.2111

Final answer:-

Distance between the two points

AB = √52 = 7.2111
