Answer:
The first, third, and fourth options are less than 50% shaded.
Step-by-step explanation:
Each model has 100 squares, and if you count the squares, the first, third, and fourth models have less than 50 squares shaded in.
9.50 + (2.20)r
For example if he fixed 3 watches
9.50 + (2.20)3
We plug in 3 for r and he makes 6.60 extra.

Answer:
Just two corrections! See attached image.
Step-by-step explanation:
The product of 8 and b taken <u>from</u> 10 means begin with 10 and subtract 8b from it.
8 times the difference of 10 and b means find 10 - b first, <u>then</u> multiply by 8.
Answer:
x = 0
, y = 7/6
Step-by-step explanation:
Solve the following system:
{18 y - 12 x = 21
6 x - 9 = -9
In the second equation, look to solve for x:
{18 y - 12 x = 21
6 x - 9 = -9
Add 9 to both sides:
{18 y - 12 x = 21
6 x = 0
Divide both sides by 6:
{18 y - 12 x = 21
x = 0
Substitute x = 0 into the first equation:
{18 y = 21
x = 0
In the first equation, look to solve for y:
{18 y = 21
x = 0
Divide both sides by 18:
{y = 7/6
x = 0

Answer: {x = 0
, y = 7/6
