Answer:

5. X = 2, Y = 3

6. X = 3, Y = 8

Step-by-step explanation:

For 5, it is easier to use the substitution method to solve. Plug the Y equation into the Y value of the first equation and simplify.

-3x - 2(5x-7) = -12

-3x - 10x + 14 = -12

-13 = -26x

x = 2

Then, plug the X value into either equation.

y = 5(2) -7

y = 3

For 6, it is easier to use the elimination method to solve. Multiply the first equation by 2 in order to eliminate 4y.

10x - 4y = -2

x + 4y = 35

Add these equations and simplify.

11x = 33

x = 3

Then, plug the X value into either equation.

3 + 4y = 35

32 = 4y

y = 8

Answer:

Step-by-step explanation:

2l-3w

The expression is 2l- 3w

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given:

Twice the length (l) less three times the width (w).

So,

Twice the length (l)  = 2l

three times the width (w). = 3w

So, Twice the length (l) less three times the width (w).

=2 l - 3w

Answer:

10 inches

Step-by-step explanation:

The top of the jack is 10 inches from ground.

A parallelogram is a two-pair quadrilateral with parallel sides. A parallelogram has opposite sides that are the same length and have opposite angles that are the same size. Additionally, the interior angles on the same transversal side are supplemental. 360 degrees are the sum of all the interior angles.

A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.

Given Jack is in shape of parallelogram,

height of crank of jack from ground  = 5 inches

to find the distance from ground to top of jack

since crank is at centre of jack and bottom  to top of jack makes the diagonal of parallelogram,

distance from crank to top of jack is 5 inches,

because The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal.

total length from ground is 5 + 5 = 10 inches

Hence length from ground to top of jack is 10 inches because diagonals bisect each other.

Given:

Mason misses 25% of the free throws he attempts in a season.

Number of missed free throws = 52

To find:

The total number of free throws.

Solution:

Let x be the total number of free throws.

Mason misses 25% of the free throws he attempts in a season.

Number of missed throws = 25% of x

Number of missed free throws = 52

Now,

[tex]\dfrac{25}{100}x=52[/tex]

[tex]\dfrac{1}{4}x=52[/tex]

Multiply both sides by 4.

[tex]x=52\times 4[/tex]

[tex]x=208[/tex]

Therefore, the total number of free throws is 208.

Step-by-step explanation:

So, we have to find the slope of the line. We are given two points, so we can use those:

(x1,y1) = (-4,6)

(x2,y2) = (1,2)

m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5

Also, we know that point-slope is of the form:

(y-y1) = m*(x-x1)

It doesn't matter which point you use, though, you can also use:

(y-y2) = m*(x-x2)

So we can plug the variables into the equation and get:

(y-2) = -4/5*(x-1)

OR

(y-6) = -4/5*(x+4)

Answer:

Let's suppose the next case:

We have a bag, where there are 5 red marbles, and 5 blue marbles.

We have a total of 10 marbles.

Suppose that we pick a marble and we do not replace it, and suppose that the first one is a red marble.

Then now we have in the bag a total of 4 red marbles and 5 blue marbles.

Now let's find the probability of picking a blue marble, this will be equal to the quotient between the number of blue marbles (5) and the total number of marbles (9)

P = 5/9

Now, suppose that instead of a red marble in the first pick, we had a blue marble.

Then now we have 4 blue marbles and 5 red marbles in the bag.

Again, the probability of picking a blue marble will be equal to the quotient between the number of blue marbles (4) and total numbergof marbles (9)

P = 4/9

Then the first pick does affect the probabilities for the second pick, this means that if we do not replace the first marble we pick, then the events will be dependent.

Now, if we replaced the first marble we picked (we put it again in the bag) then the number of blue marbles and red marbles is always the same, then in this case bot events will be independent (the first event will not affect the second event)

Answer:

The percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]

Step-by-step explanation:

Estimated length of a line = 12.4 inches

Actual length of the line = 15.7 inches

Error = 15.7 - 12.4 = 3.3 inches

Percent error of the measurement [tex]=\frac{3.3}{15.7}(100)=21.02[/tex] ≈ 21.0

So, the percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]

Complete question is;

Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales. Today, ticket sales were three-fourths as much as yesterday, and food sales were down by $33.50. Nina wrote the expression ¾(1440) + 295.25 + (-33.50) to find today's total sales. Is she correct? Explain.

Answer:

Nina is correct

Step-by-step explanation:

Today, ticket sales were three-fourths as much as yesterday.

Thus, it means today's ticket sales will now be; $¾(1,440) = $1080

Now, food sales were down by $33.50.

Thus, food sales for today is;

$295.25 - $33.50 = $261.75

Thus,total ticket sales for today is;

1080 + 261.75 = $1341.75

From the expression of Nina which is ¾(1440) + 295.25 + (-33.50) ;

When calculated it gives the same value we got as $1341.75.

This means that Nina is correct
