Answer:

98 copies

Step-by-step explanation:

25% of 78 is 19.5

19.5 + 78 = 97.5

Because there can't be half of a copy we round up based on the decimal. Therefore the answer would 98 copies.

Answer:

[tex]Tatiana = \$8.35[/tex]

Step-by-step explanation:

Given

[tex]Total = \$31.50[/tex]

[tex]Felicia = \$4.25[/tex]

[tex]Ingrid = 2 * Felicia[/tex]

[tex]Meiko = \$1.90 + Ingrid[/tex]

Required

Determine amount spent by Ingrid

We have that:

[tex]Ingrid = 2 * Felicia[/tex]

Substitute $4.25 for Felicia

[tex]Ingrid = 2 * \$4.25[/tex]

[tex]Ingrid = \$8.5[/tex]

We also have that:

[tex]Meiko = \$1.90 + Ingrid[/tex]

Substitute $8.5 for Ingrid

[tex]Meiko = \$1.90 + \$8.50[/tex]

[tex]Meiko = \$10.40[/tex]

The total can be represented as thus:

[tex]Felicia + Ingrid + Meiko + Tatiana = Total[/tex]

[tex]\$4.25 + \$8.50 + \$10.40 + Tatiana = \$31.50[/tex]

[tex]\$23.15+ Tatiana = \$31.50[/tex]

Collect Like Terms

[tex]Tatiana = \$31.50 - \$23.15[/tex]

[tex]Tatiana = \$8.35[/tex]

Answer:

I have attached a picture of the graph.

Step-by-step explanation:

So for 3 miles, they are charged $6 and for 5 miles, $8. This means that for 5-3 = 2 miles, they are charged $8-$6 = $2.

2 miles = $2

1 mile = $1

We will apply this charging rate for 3 miles since we know there is a flat fee added into it too.

3 miles = $3

Flat fee = $6 - $3

            = $3

That means that at 0 miles, there is a flat fee of $3, and so the graph would start at 3 on the x-axis even when the y-axis (representing the miles) is at 0 (0 miles).

You also know that for each mile, there is an increase of $1, so the graph should increase upwards at 1 dollar per 1 mile. I have attached the graph for you.

Answer:

x ≤ 3

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define inequality

3x ≤ 9

Step 2: Solve for x

Here we see that any solution x less than or equal to 3 would be a solution of the inequality.

Answer:

Set A is a function

set B is not a function

The given equations are

[tex]2x-3y=-1\cdots(i) \\\\y=x-1\cdots(ii)[/tex]

(a) Solution by graphing both the equations:

Graph for both the equations (i) and (ii) are in the figure. The point of intersection of both the graph is the solution of the equations.

From the graph, the point of intersection is (4,3)).

Hence, the required solution is (4,3).

(b) Solution by elimination method:

Equations (ii) can be written as -x+y=-1, now multiply it by 2, we have

[tex]-2x+2y=-2\cdots(iii)[/tex]

Add equations (i) and (iii), we have

2x-3y=-1

-2x+2y=-2

__________

[tex]\Rightarrow -3y+2y=-1-2\\\\ \Rightarrow -y=-3\\\\ \Rightarrow y=3.[/tex]

Putting the value of y=3 in equation (i), we have

[tex]2x-3\times 3=-1 \\\\\Rightarrow 2x=-1+9=8 \\\\\Rightarrow x=8/2=4[/tex]

Hence, the required solution is (4,4).

(c) Solution by substitution method:

Substituting the value of y from equation (ii) to equation (i), we have

[tex]2x-3(x-1)=-1 \\\\\Rightarrow 2x-3x+3=-1 \\\\\Rightarrow -x=-1-4=-4 \\\\\Rightarrow x=4[/tex]

Putting the value of x=4 in equation (i), we have

[tex]y=4-1=3[/tex].

Hence, the required solution is (4,3).

Fill the 5 gallon jug.

Pour the 5 gallon jug into the 3 gallon jug.

Empty the 3 gallon jug and pour the remaining 2 gallons in the 3 gallon jug.

Fill the 5 gallon jug and pour 1 gallon into the 3 gallon jug (remember it will only take one gallon)

Viola the remaining 5 gallon jug will have exactly 4 gallons remaining.

Answer:

use 4/5 of the 5 gallon jar or 1 and 1/3 of the 3 gallon jar

I included a chart so next time you don't need to worry

Answer:

1138

Step-by-step explanation:

From the information given:

We can represent it perfectly in an exponential form:

[tex]m = p(q)^x[/tex]

where;

p = initial value = 120

q = base of the exponential form

q = 1 + r

here; r = rate in decimal = 10% = 0.1

Then q can now be = 1 + 0.1 = 1.1

Replacing it into the exponential form, we get:

[tex]m = 120(1.1)^x[/tex]

where;

x = number of days and m = number of shoppers

Thus:

For the first day:

[tex]m = 120(1.1)^x[/tex]

m = 120

For the second day:

[tex]m = 120(1.1)^1[/tex]

m = 132

For the third day:

[tex]m = 120(1.1)^2[/tex]

m = 145.2

For the fourth day

[tex]m = 120(1.1)^3[/tex]

m = 159.72

For the  fifth-day

[tex]m = 120(1.1)^4[/tex]

m = 175.692

For the sixth-day

[tex]m = 120(1.1)^5[/tex]

m = 193.2612

For the seventh-day

[tex]m = 120(1.1)^6[/tex]

m = 212.58732

Thus; the total numbers of shoppers for the first 7 days is:

[tex]= 120+ 132 + 145.2 + 159.72 + 175.692+193.2612+212.58732[/tex]

= 1138.46052

≅ 1138

Answer:

Option D: The number of multiple-choice question points plus the number of  short-answer question points is 80 is the correct answer.

Step-by-step explanation:

Given that:

Points worth of test = 80 points

There are Multiple choice questions worth 2 points and short answer questions worth 4 points.

2x+4y=80

Thus,

The number of multiple choice questions points plus the number of short answer question points is 80.

Hence,

Option D: The number of multiple-choice question points plus the number of  short-answer question points is 80 is the correct answer.

-c + 1 > 2

-c > 2-1   Move 1 to subtract.

-c > 1

c < -1      When the coefficient is negative, moving the negative to another side as changing the sign of Inequality to opposite.
