Step-by-step explanation:

For this one you just have to plug in the x in every equation and solve it. If the answer is true it's true, but if it's false it's false.

Let's solve each of these...

Number 1:

[tex]9-3x=0\\9-3(3)=0\\9-9=0\\0=0[/tex]

As you can see 0 does equal itself so this one is true.

Number 2:

[tex]3x+1=9\\3(3)+1=9\\9+1=9\\10\neq9[/tex]

10 does not equal 9 so this one would be false.

Number 3:

[tex]5x-7=1\\5(3)-7=1\\15-7=1\\8\neq1[/tex]

This one is also false.

Number 4:

[tex]2x+4=10\\2(3)+4=10\\6+4=10\\10=10[/tex]

This one is true.

Number 5:

[tex]\frac{x}{3}+5=6\\\frac{(3)}{3}+5=6\\1+5=6\\6=6[/tex]

This one is true.

Number 6:

[tex]\frac{9}{x}-1=4\\\frac{9}{(3)}-1=4\\3-1=4\\2\neq4[/tex]

This one is false.

Rewrite each fraction with a denominator of 24 2/3 5/8

Answers

Answer:

A)16/24

B)15/24

Step-by-step explanation:

We were told to rewrite so that the denominator will be 24

A)2/3

This can be rewritten as 16/24, so that the denominator is now 24. And if we divide the numerator (16) by factor of 8 and the denominator (24) by factor of 8. Then we have 2/3.

OR

[2/3 × 8/8] = 16/24

B)5/8

This can be rewritten as 15/24, so that the denominator is now 24. And if we divide the numerator (15) by factor of 3 and the denominator (24) by factor of 3. Then we have 5/8

OR

(5/8 × 3/3)= 15/24

The graph shows the relationship between the number of pounds of

What is the cost of 1 pound of apples? Enter the answer in the box.

Answers

Given:

The graph shows the relationship between the number of pounds of  apples purchased and the total cost of the apples.

To find:

The cost of 1 pound of apples.

Solution:

We need to find the slope of the line to get the cost of 1 pound of apples.

From the given graph it is clear that the line passes through two points (0,0) and (2,3). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-0}{2-0}[/tex]

[tex]m=\dfrac{3}{2}[/tex]

[tex]m=1.5[/tex]

Therefore, the cost of 1 pound of apples is $1.5.

Find the coordinate of the missing vertex of rectangle ABCD with A(-5,4), B(3,4), and D(-5,-3).

Answers

Answer:

(3 , -3)

Step-by-step explanation:

The missing vertex of rectangle ABCD is C(3, -3).

What are the coordinates?

Coordinates are a collection of numbers that aid in displaying a point's precise location on the coordinate plane.

Given:

ABCD is a rectangle.

And the vertices are A(-5,4), B(3,4), and D(-5,-3).

We know,

the parallel sides of a rectangle are equal.

Plotting coordinates of all the vertex.

We get,

the missing vertex is C(3, -3)

To verify that segments are equal or not:

Now, AB = √{(-5 - 3)² + (4 - 4)²} = √{64} = 8 units

CD = √{(-5 - 3)² + (-3 + 3)²} = √{64} = 8 units.

Therefore, the missing vertex is C(3, -3).

Weekday hours tripled but your budget of $220 for 26
parking hours remain the same. How many weekend hours
can you purchase now that the weekday hours have
increased?

Answers

Answer:

8 weekend hours can now be purchased.

Note: The prior information required is:

You purchase 26 "parking hours" that you can use over the next month to park your food truck at the fair. Weekday hours cost $2/hour and weekend hours cost $10/hour.

Step-by-step explanation:

Initial cost of weekday hours = $2/ hour

Since the cost of the weekday hours is tripled, new cost = $2/ hour × 3 = $6/ hour

Total week hours purchased = 26 hours

Let the number of weekend hours be x; number of weekday hours will be 26 - x

Since the budget remains the same, therefore, the total cost of weekday parking hours and weekend parking hours will be equal to $220as expressed below;

(26 - x) × $6 + $10 × x = $220

$10x - $6x + $156 = $220

$4x = $(220 -156)

x = 64/4

x = 8 hours

Therefore, 8 weekend hours can now be purchased
