Answer:
X= 11
Step-by-step explanation:
That equation becomes -7x+15x-30 =58
And add them all up giving you 8x-30=58
Add 30 to both sides
8x=88
Divide 88 by 8 which gives you 11
I need a lot of help with this question!!!!!!
CLICK THE PICTURE
The x is going to =7.5 i belive is right
14 kinds of doughnuts
she need to make 8 of each
14 x 8 = 112
She needs to make 112 doughnuts total
She's already cooked 4 dozen
4 x 12 = 48
112-48= 64
She needs to make 64 doughnuts still
Second option: This is a perfect cube.
Fourth option: The side length is 6 centimeters.
Fifth option: Taking the cube root of the volume will determine the side length.
Step-by-step explanation:
You know that the volume of a cube can be calculated with:
Where s is the lenght of any side of the cube.
Since you know the volume of this cube, you can calculate the side lenght by solving for "s". You can make this taking the cube root of the volume.
Therefore, you get that the side lenght of this cube is:
(Since it has exact cube root, it is a perfect cube)
X=64
Opposite angles are congruent
