Substituting y=x-6 into the equation,

3x + 2(x-6) = 3x + 2x - 12 = 5x - 12

5x - 12 = 8
5x = 20
x = 4

Lisa makes a cherry pie and an apple pie. She cuts the cherry pie into six equal wedges and she cuts the apple pie into eight eq
ale4655 [162]

Both the pies at first have 360* as their initial complete angles.

The Cherry Pie is cut into 6 parts equal and the angular width of each piece will be 360/6=60*...therefore, each piece is 60*.

the Apple Pie is cut into 8 parts and the angle of each piece would be 360/8=45*...therefore, each piece is 45*.

Now the angular difference between the pieces of the 2 pies is 60*-45* = 15*.

Therefore the Cherry pie's piece is 15* greater than the Apple pie's piece.

Brenden Read 3/4 of a book that was 7/8 inches thick. How much of the book, in inches, did he read?
Firdavs [7]

Answer:

A

Step-by-step explanation:

To find how much 3/4 of a number is, multiply 3.4 by the number. Since the book is 7/8 inches thick, Brenden read 3/4 * 7/8.

To multiply fractions, multiply straight across numerator and denominator.

3/4 * 7/8 = 3*7/ 4*8 = 21/32

I only need help with number 9 plz
Varvara68 [4.7K]

Answer:

<h2>Letter C</h2>

Step-by-step explanation:

If we look on the number line we see that there is a point on -3, another point on -1, 2, and 7.

These points tell us our answer, but the question states it doesn't have to be in any order.

As we look at answer A we see -3, 1, 2, and -7. That's incorrect since there is no positive 1 nor an -7.

As we look at answer B we see -3, 7, 1, and -2. That's incorrect since there is no positive 1, and not a -2.

As we look at answer D we see -2, 3, 1, and 7. That's incorrect since there is no positive 2, no positive 3, and no negative 1.

C has to be the correct answer since it's the only answer left and has the 4 numbers that are on the number line.

Therefore, the correct answer is C.

Best of Luck to you.

A rectangle has a length of (x + 4) centimeters and a width of 12x centimeters. If the perimeter is 26 centimeters, what is the
mars1129 [50]

Width of rectangle is 8.4 cm

Step-by-step explanation:

Length of rectangle = x+4

Width of rectangle = 12x

Perimeter = 26 cm

We need to find width of rectangle.

The formula used is:

Perimeter=2(length+width)

Putting values and finding x first:

Perimeter=2(length+width)

26=2(x+4+12x)

26=2(13x+4)

26=26x+8

26-8=26x

26x=18

x=\frac{18}{26}

x=0.7

So, value of x is 0.7

Now width= 12x = 12(0.7)

=8.4 cm

So, width of rectangle is 8.4 cm.
