69 hr 
12 - 15 % = 10.2
700 / 10.2 = 68.62 round up 69 check 
12*69 = 828
828 / 100 =8.28       8.28 = 1%
8.28 * 15 = $124.20 
828 - 124.2 = 703.8

12 minus 15% is 10.20 so you have $2.80 per hour so 2.80 per hour times 250 hours gives you $700

the equation of the line / is -3y+4x=9. write the equation of a line that is parallel to the line / and passes through the point
nekit [7.7K]

Hey!

So before trying to figure out the equation of the line, lets change -3y+4x = 9 into slope-intercept form:

-3y + 4x = 9

-3y = -4x + 9

y = (4/3)x - 3

Now that you have the equation in slope-intercept form we can find the equation of the line parallel to this. One thing that we are given from this equation is the slope of the line, the slope for two parallel lines are the same. So we know that the slope of the line is 4/3. We are also given another point on the line and we can plug this point in for y and x to find the y-intercept or b:

6 = (4/3)(-12) + b

6 = -16 + b

22 = b

Now that we know b, we have both the y-intercept and the slope so our equation would be:

y = (4/3)x + 22

Students in the seventh grade at Texas Intermediate School were surveyed to find out their favorite store. The graph below repre
natta225 [31]

Answer:

Option d is correct.

The number of students that chose Target as their favorite store over Ross = 4 students.

Step-by-step explanation:

The graph of the question is obtained from another brainly question on here. But uploading it will lead to deletion of this answer as it would be violating the community guidelines here.

So, I'm going to describe the graph.

The graph provided with the question is a pie chart, with each region clearly shown and the corresponding percentage for each of the students' favourite stores that come up in the survey given as

TJMax - 20%

Wal-Mart - 25%

Ross - 20%

Target - 25%

Others - 10%.

How many more students surveyed chose Target as their favorite store over Ross?

Total number of students sampled = 80

Number of students that picked Target

= 25% × 80 = 20 students

Number of students that picked Ross

= 20% × 80 = 16 students.

Number of students that chose Target as their favorite store over Ross = 20 - 16 = 4 students.

Hope this Helps!!!

2(x + 2) + 3z = 2(x + 1) +1
Oxana [17]

Answer:

Answer:x=

−3z−1

0

Step-by-step explanation:x=

Step 1: Add -2x to both sides.

2x+3z+4+−2x=2x+3+−2x

3z+4=3

Step 2: Add -3z to both sides.

3z+4+−3z=3+−3z

4=−3z+3

Step 3: Add -4 to both sides.

4+−4=−3z+3+−4

0=−3z−1

Step 4: Divide both sides by 0.

0

0

=

−3z−1

0

x=

−3z−1
