A math student goes to an office supply store and purchases a total of 16 spirals and pencils. Each spiral costs $3. 50, and each pencil costs $1. 25. If the student spent a total of $29, how many pencils did the student purchase?.

The **student **purchase **12 pencils**

If a math student goes to an **office supply** store and purchases a t**otal of 16 spirals and pencils**, then;

x + y = 16 .................. 1

If each spiral costs $3. 50, and each pencil costs $1. 25 and the student spent a **total of $29,** hence;

1.25x + 3.5y = 29 ................. 2

Solve both equations** simultaneously**

x + y = 16 .................. 1 * 1.25

1.25x + 3.5y = 29 ................. 2 * 1

__________________________________

1.25x + 1.25y = 20.

1.25x + 3.5y = 29

**Subtract **both equations

1.25y - 3.5y = 20 - 29

-2.25y = -9

y = 9/2.25

y = 4

**Substitute** y = 4 into **equation 1:**

x + y = 16

x = 16 - 4

x = 12

This means that the **student **purchase **12 pencils**

6) Error Analysis. Analyze the work below, describe the error then

determine the correct value for x.

26 = 4x - 2

24 = 4x

6 = x

**Answer:**

The error is that 2 should have been added to both sides, 7 = x

**Step-by-step explanation:**

a) work out the size of angle x.

b) give reasons for your answer.

**Answer:**

x=30

**Step-by-step explanation:**

105 is also the same as angle b which is also the same as the angle opposite.

so

150+150=300

360-300=60

60/2=30

hope that helps.

plz mark as brainliest if correct

thank you

**Answer:**

x=75°

**Step-by-step explanation:**

the angle that is 105° and the angle that is x makes a co interior angle.

the two angles belonging to that co interior angle will always add up to 180°.

so in this case, 180° - 105° = x

answer = **x****=****7****5****°**

**Answer:**

c=$214.28

**Step-by-step explanation:**

Since you have the (p) value (p=285.7) all you need to do is plug it into one of these two equations

c=0.75p --- c=0.75(285.7)= 214.275-- 214.28

c=0.4p+100 --- c= 0.4(285.7) + 100 --- c= 114.28 +100 -- c= 214.28

either way its the same, just plug it into one or the other

How to solve for x using the equation: 12 = -4 (- 6x - 3)

I don’t know how to explain it so I am just giving the equation

12=-4(-6x-3x)

Divide both sides by 4

12/4=-4(-6x-3x)/4

3=-4(-6x-3x)/4

3=-(-6x-3x)

3=9x

9x/9 = 3/9

Divide both sides by 9

x=1/3

12=-4(-6x-3x)

Divide both sides by 4

12/4=-4(-6x-3x)/4

3=-4(-6x-3x)/4

3=-(-6x-3x)

3=9x

9x/9 = 3/9

Divide both sides by 9

**Answer: GOONNA BE BE SIRRRRR BTW I HAVE IPHONE 21345678**

**Step-by-step explanation:**

There are 900 seats on a train. 540 of the seats are empty. What percentage of the seats on the train are empty?

60% of the seats on the train are empty

you have to divide 900 by 9 to get 100 because percents are out of 100, then you have to divide 540 by 9 also.

**Answer:**

60%

**Step-by-step explanation:**

Because there are 540 empty, and 900 total, you need to divide 540 by 900.

540/900=54/90=6/10=60/100

When you get 60/100, or 0.6, you know that it is 60 percent because percent is out of 100.
