Step-by-step explanation:

15 multiplies to both 3 and 2x amd the result is 45+2x

Final answer:

To write an expression equivalent to 45 + 30x using the distributive property, factor out the common factor of 15 to get 15(3 + 2x).

Explanation:

To write an expression equivalent to 45 + 30x using the **distributive property**, we can factor out the common factor. This can be done as follows:

Factor out 15, so 45 + 30x becomes 15(3 + 2x).

Therefore, an expression equivalent to 45 + 30x using the distributive property is 15(3 + 2x).

The cost of old computer is $ 357

Solution:

Let "x" be the cost of old computer

From given,

Cost of new computer = $ 709

Blairs new computer cost 5$ less than twice the cost of her old computer

Therefore,

Cost of new computer = twice the cost of old computer - 5

Cost of new computer = 2x - 5

709 = 2x - 5

2x = 709 + 5

2x = 714

Divide both sides by 2

x = 357

Thus the cost of old computer is $ 357

Answer:

$357

Step-by-step explanation:

709=2x-5      

+5           +5

cross the right column out

709+5 = 714

714=2x

divide 714 by 2 and get 357

The solution is x = 8 and y = -5

Solution:

Given system of equations are:

x + y = 3 ------ eqn 1

3x + 2y = 14 ------ eqn 2

We have to find the solution to the equations

We can use substitution method to solve

From eqn 1,

x + y = 3

Isolate for "x"

x = 3 - y ------ eqn 3

Substitute eqn 3 in eqn 2

3(3 - y) + 2y = 14

9 - 3y + 2y = 14

-y = 14 - 9

-y = 5

Substitute y = -5 in eqn 3

x = 3 - (-5)

x = 3 + 5 = 8

Thus the solution is x = 8 and y = -5

To find the number in the middle of 15 and 24, you calculate the mean, which is (15 + 24)/2, resulting in 19.5.

Explanation:

How to Calculate the Number in the Middle of 15 and 24

To calculate the number in the middle of two values, we are essentially seeking the mean or average of those two numbers. This can be done by adding the two numbers together and then dividing by the number of values, which is 2 in this case. Thus, the calculation would be (15 + 24)/2.

Let's do the math: (15 + 24)/2 = 39/2 = 19.5.

Therefore, the number in the middle of 15 and 24 is 19.5.

Answer:

Step-by-step explanation:

hello :

(7-2i)/(4 +3i)

=(7-2i)×(4-3i)/(4 +3i)×(4-3i)

but : (7-2i)×(4-3i) =28-21i-8i+6i²

(7-2i)×(4-3i) = 22-29i   ....i² = -1

(4 +3i)×(4-3i) = 4²-(3i)²...(identity)

                   = 16+9 =25

so :

(7-2i)×(4-3i)/(4 +3i)×(4-3i)

=(22-29i)/25

(7-2i)/(4 +3i) = 22/25 -29/25i

(form : a+ib)

To divide complex numbers, multiply the numerator and denominator by the conjugate of the denominator.

To divide complex numbers, we need to multiply the numerator and denominator by the conjugate of the denominator. The conjugate of 4 + 3i is 4 - 3i. So, we have ((7 - 2i) * (4 - 3i)) / ((4 + 3i) * (4 - 3i)).

Multiplying the numerators and the denominators, we get (28 - 21i - 8i + 6i^2) / (16 - 12i + 12i - 9i^2).

This simplifies to (28 - 29i - 6) / (16 + 9).

Finally, dividing the real parts and the imaginary parts separately, the quotient is:

Quotient = (22 - 29i) / 25

Answer:

$12,000

Step-by-step explanation:

Let's say the husband's income was $H, and the Wife's was W.

h + w = 75,000

H = 5w + 15, 000

Substitute that for H.

5w + 15,000 + w = 75,000

6w + 15,000 = 75,000

6w=60,000

w=12,000, So the wife earned $12,000.

The student with the lowest unit rate is Mickey, with a unit rate of 0.3 miles per minute.

Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.

The speed formula is speed = distance / time.

We are given that;

Equation d=m

Susan distance travelled=3 miles in 5 minutes

Now,

To find the unit rate, we need to divide the distance traveled by the time taken. Let's start by calculating the unit rate for each student:

Jason: The equation given for Jason's distance traveled is d = m, where d is the distance traveled in m minutes. Therefore, his unit rate is 1 mile per minute.

Susan: She traveled 3 miles in 5 minutes. To find her unit rate, we divide 3 miles by 5 minutes:

Unit rate = 3 miles / 5 minutes = 0.6 miles per minute

Mickey: The points on Mickey's distance vs time graph are (20,6), (40,12), and (60,18). We can use these points to calculate the unit rate for Mickey.

Between the points (20,6) and (40,12), the distance traveled is 12 - 6 = 6 miles, and the time taken is 40 - 20 = 20 minutes. Therefore, the unit rate is:

Unit rate = 6 miles / 20 minutes = 0.3 miles per minute

Between the points (40,12) and (60,18), the distance traveled is 18 - 12 = 6 miles, and the time taken is 60 - 40 = 20 minutes. Therefore, the unit rate is:

Unit rate = 6 miles / 20 minutes = 0.3 miles per minute.

Therefore, by distance given the answer will be 0.3 miles per minute.

QUESTION NOT CLEARLY STATED

Step-by-step explanation:

Answer:

43 questions in total

Step-by-step explanation:

the original equation with the unknown (total number of questions on the test) will look like this

[tex] \frac{total \: number \: of \: questions \: on \: exam}{24 \: answered \: questions} = 80\%[/tex]

we know this because to work out a percentage in the 1st place you need the total ÷ number (in this case it's ÷ how many questions out of the total she did answer)

now you rearrange.

you need to move the 24 to get the total on it's own here's how you do it

[tex] \frac{tot \: num \: of \: qs}{24} \times 24 = 80\% \times 24[/tex]

what you do to one side of equation you have to do to the other. the 24 and 24 on the left will cancel because 24÷24=1 and we don't write

got mum of Q's x 1= 80 x 24

now you convert % to decimal

[tex]80\% \times 100 = 0.80[/tex]

replace

[tex]tot \: num \: qs \: = 24 \times 0.80 = 19[/tex]

now you take the original and + the 19

[tex]24 + 19 = 43[/tex]

therefore there are a total of 43 questions on the exam

To find the total number of questions on the test, we set up a ratio where 24 questions represents 80%. By comparing it to a ratio where X represents 100%, and solving for X, we get the total number of questions.

The question pertains to the concept of percentages. In Sarah's case, she answered 24 questions correctly and got an 80%, meaning that these 24 questions represent 80% of the total questions on the test. Hence, to find the total number of questions on the test, we set up a ratio such as this: 24 is to 80 as X (total questions) is to 100. We solve for X by multiplying the cross products and dividing by 80. The result will give us the total number of questions on the test.

Step-by-step explanation: I just took the test

To determine the value of x, various methods are used depending on the context, including setting up proportions for scale models, applying the quadratic formula, solving linear equations, and establishing ratios.

To find the value of x, we have various scenarios illustrating different mathematical concepts, such as proportions, the quadratic formula, and linear equations. Each scenario requires specific steps to solve for x, but they all center on mathematical problem-solving skills.

When dealing with proportions, such as a scale model, you set up a proportion correlating the scale size to the actual size and then cross multiply to solve for x. In the situation where a quadratic equation is involved, you apply the quadratic formula to determine the value of x, taking care to discard any solutions that do not make sense in the physical context of the problem, such as negative distances.

For linear equations, you enter the given data into a calculator or computer and solve for x, while ensuring you round off to the accuracy required, typically four decimal places. Ratios and scale factors also play a role in determining x, where you establish a ratio based on given dimensions and solve for the unknown.

Answer:

equation of line m is x=3

equation of line n is y=-4

Step-by-step explanation:

Line m has no y intercept, and its x-intercept is (3,0).

When a line has no y intercept then it is a vertical line

for any vertical line the equation is x= x1

(3,0) is (x1,y1)

so equation of line m is x=3

Line n has no x intercept and its  y -intercepts is (0-4).

When a line has no x intercept then it is a horizontal  line

for any horizontal line the equation is y= y1

(0,-4) is (x1,y1)

so , the equation of line n is y=-4

Answer:

Step-by-step explanation:

y intercept is 3

y - 4 = 3 ( x - 4)

y - 4 = 3x - 12

y < 3x - 8

not equal to because the line is dashed.

not greater than because the shading is below the line

x > –5

Solution:

Given expression is –5 < 2x + 5.

Step 1: Let us first switch the sides.

⇒ 2x + 5 > –5

Step 2: Subtract 5 from both side of the inequality.

⇒ 2x + 5 –5 > –5 –5

⇒ 2x > –10

Step 3: Divide by 2 on both sides of the inequality.

[tex]$\Rightarrow\frac{2x}{2} >\frac{-10}{2}[/tex]
