400/2=200

200-25=175

J=175

F=225

Step-by-step explanation:

175J+225F=400

Answer:

Finn earned 225 and Jake earned 175

Step-by-step explanation:

400 divided by 2= 200

200-25=175 which would be what jake earned.

200+25=125.

Answer:

21.46

Step-by-step explanation:

we know that 10yd is the diameter of the unshaded circle. so we will use this to find out the area of the circle. if a diameter of a circle is 10yd, the area is about 78.54 (considering that pi=3.14) to find the area of the shaded region, we can pretend that the entire square is shaded, and then take the unshaded away. if the square was completley shaded, the answer would be 100. but there is a circle inside of the square unshaded, with a area of 78.54, so we need to solve for 100-78.54. this results in our final answer, 21.46

[tex]7\frac{2}{3}[/tex]

Step-by-step explanation:

[tex]3\frac{1}{9}p+5-\frac{1}{3}p[/tex]

Put it into a different form to make it easier.

[tex]3\frac{1}{9}p-\frac{1}{3}p+5[/tex]

Add the fractions. We need to figure out the LCM to figure out the common denominator. The LCM is 9 in this case.

[tex]3\frac{1}{9}-\frac{3}{9} +5[/tex]

I like to convert into imroper fractions. This is optional though.

[tex]\frac{28}{9} -\frac{3}{9} +5[/tex]

[tex]\frac{24}{9} +5[/tex]

[tex]\frac{8}{3}+5[/tex]

Get a common denominator. The LCM is 3.

[tex]\frac{8}{3}+\frac{15}{3}[/tex]

[tex]\frac{23}{3}[/tex]

Make this fraction into a mixed number.

[tex]7\frac{2}{3}[/tex]

Answer:

15x to the power of 2

Step-by-step explanation:

3x × 5x = ?

Here we will do more than give you the solution to 3x × 5x. We will also explain and teach you how we came up with the answer, so you can understand it and solve similar problems in the future without help.

In this problem, 3 and 5 are the coefficients and two Xs are the variables. When a coefficient is next to a variable there is an invisible multiplication sign. So you could rewrite the problem as follows:

3 × x × 5 × x =

So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:

3 × 5 = 15

x × x = x2

Then you put the answers together and make the multiplication sign invisible again to get the following answer:

3x × 5x = 15x2
