10-12 please help, find the missing number and once you found the missing number and answered it you make sure it’s the solution

irinina [24]

10. Infinitely many solutions:

$2(x-1)+6x=4(?-1)+2.$

Simplify this equation:

$2x-2+6x=4\cdot ?-4+2,\\ \\8x-2=4\cdot ? -2,\\ \\8x=4\cdot ?$

When $?=2x,$ the equation becomes

$8x=8x \text{ or } 0=0.$

This equality is true for all x, thus the equation has infinitely many solutions.

11. The equation $5x-(x-2)=2x-(?)$ should have one solution x=-1.

First, simplify the equation:

$5x-x+2=2x-?,\\ \\4x+2=2x-?,\\ \\2x+2=-?,\\ \\?=-2x-2.$

This equation will have solution x=-1 when

$?=-2\cdot (-1)-2=2-2=0.$

Therefore, the initial equation is

$5x-(x-2)=2x.$

12. The equation $-(x-8)+4x=2\cdot ?+x$ should have infinitely many solutions.

Simplify it:

$-x+8+4x=2\cdot ?+x,\\ \\2x+8=2\cdot ?,\\ \\2(x+4)=2\cdot ?.$

When $?=x+4,$ this equation will have infinitely many solutions.

Answer:

Step-by-step explanation:

Find out how much pie was leftover from each pie:

Apple pie: 3/4, 4 - 3 = 1, 1/4

Blackberry: 1/2, 2 - 1 = 1, 1/2

Blueberry: 1/8, 8 - 1 = 7, 7/8

Cherry: 5/8, 8 - 5 = 3, 3/8

Peach: 3/4, 4 - 3 = 1, 1/4

There are 1/4, 1/2, 7/8, 3/8, and 1/4 pies left. The LCD if these numbers is 8, since 2*4 = 8, 4*2 = 8, and 8*1 = 8

1/4 = 2/8

1/2 = 4/8

7/8 = 7/8

3/8 = 3/8

1/4 = 2/8

2 + 4 + 7 + 3 + 2 = 18, so 18/8 pies, or 2 2/8, or 2 1/4

Find the measure of angle ABD if the measure of angle DBC is 42 degrees and the measure of angle ABC is 88 degrees

snow_lady [41]

First, realize that angle ABC is the sum of the two other angles. Hence, form an equation in which you subtract the measure of one of the angles from angle ABC to get the measure of the other angle -- the one you are solving for.
