Answer:

x = 5

Step-by-step explanation:

Step 1: Write equation

3x - 4 = 2x + 1

Step 2: Solve for x

Subtract 2x on both sides: x - 4 = 1

Add 4 on both sides: x = 5

Answer:

x=5

Step-by-step explanation:

3x-4=2x+1----> you subtract 2x on both sides---->x-4=1 -----> then add 4 on both sides and you get---> x=5. Hope it helped.

Answer:

(2x - 5 ) (3x^2 + 5x - 7) = 6x^3 - 5x^2 - 39x - 35

The product of 2x – 5 and 3x2 + 5x - 7equal to the product of 5x - 2 and 3x2 + 5x - 7 are not equal.

Step-by-step explanation:

Product means multiplication

Product of 2x - 5 and 3x^2 + 5x - 7

(2x - 5 ) (3x^2 + 5x - 7)

= 6x^3 + 10x^2 - 14x - 15x^2 - 25x - 35

Collect like terms

= 6x^3 + 10x^2 - 15x^2 - 14x - 25x - 35

= 6x^3 - 5x^2 - 39x - 35

Product of 5x - 2 and 3x^2 + 5x - 7

(5x - 2) (3x^2 + 5x - 7)

= 15x^3 + 25x^2 - 35x - 6x^2 - 10x + 14

Collect like terms

= 15x^3 + 25x^2 - 6x^2 - 35x - 10x + 14

= 15x^3 + 19x^2 - 45x + 14

The product of 2x – 5 and 3x^2 + 5x - 7equal to the product of 5x - 2 and 3x^2 + 5x - 7 are not equal.

They both consist of different variables in their multiplier

i cant understand your question define briefly

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2,-4) and (6,2)

The midpoint is

[tex]M = ( \frac{2 + 6}{ 2} , \: \frac{ - 4 + 2}{2} ) \\ = ( \frac{8}{2} \: , \: - \frac{2}{2} )[/tex]

We have the final answer as

Hope this helps you

Answer:

The mid point must be (4,-1)

Step-by-step explanation:

mid point= [(X1+X2)/2 , (Y1+Y2)/2]

= [ (2+6)/2 , (-4+2)/2]

= [ 8/4 , -2/2]

= (4, -1)

Answer:  13.244

Step-by-step explanation:

Answer:

b = 48 °, c = 46°

Step-by-step explanation:

c = 46 ° as between parallel lines, alternate opposite angles are equal.

since opposite angles are equal 94 ° = 46 ° + additional angel

therefore b = 94° - 46 ° = 48 ° , as sum of 2 internal angles of a triangle is equal to opposite exterior angle.

Answer:

4 more times

Step-by-step explanation:

The question says that easton paid 68 dollars for the interlocking set

Colin paid 17 dollars for his own.

We are required to find how many more times easton paid than colin

To do this we divide 68dollars by 17 dollars

68/17

= 4 times

This tells us that compared to colin, easton overpaid for his own set by 4times. Easton paid 4 more times than colin

Step-by-step explanation:

if if you put x equals to -5

it becomes -(-5)^2 which is equal to -25

Answer:

-25

Step-by-step explanation:

1) The equation is -(-5)^2

2) When you square a negative number, it will be a positive

3) So in this equation it would be -(25)

4) However, there's another negative sign in front.

5) So the answer therefore is -25

Answer: 60 feets

Step-by-step explanation:

Given the question :

Find the missing dimensions. Use the scale factor 1 inch:12 feet. A plastic toy bird has a wingspan of 5 inches. What is the actual bird wingspan?

Using a scale factor of 1 inch : 12 feet

Wingspan of plastic toy bird = 5 inches

Calculate the actual bird wingspan

(1 inch / 12 feet) = (toy bird wingspan / actual bird wingspan)

( 1 inch / 12 feet) = (5 / actual bird wingspan)

Actual bird wingspan = 5 × 12

Actual bird wingspan = 60 feets

Answer:

x = 10 4/5

Step-by-step explanation:

We want to find the value of x in the expression below;

2 1/4/x = 1 1/2/3 3/5

The best thing to do here is to turn all the mixed fractions to improper fractions. Thus, we have;

9/2/x = 3/2/18/5

= 9/2x = 3/2 * 5/18

9/2x = 15/36

9 * 36 = 15 * 2x

324 = 30x

x = 324/30 = 10 8/10 = 10 4/5

Complete question :

Kane is training for a marathon. He starts by running 3 miles during every training session each week plans to increase the distance of his runs by 1/4 mile. Let w be the number of weeks. Write and expression to show the diatance kane runs in a training session after w weeks

Answer:

(11 + w ) / 4

Step-by-step explanation:

Given the following :

Initial miles kane plans to cover per session = 3 miles

Increase in miles covered per session = 1/4 mile per week

Hence, distance covered after w weeks :

Using the sum of an arithmetic progression formula:

Tn = a + (n - 1) d

a = first term = Initial / starting distance = 3 miles

n = nth term = number of weeks = w

d = common difference = constant increase in distance per week = 1/4

Hence, after w weeks :

= 3 + (w - 1) × 1/4

= 3 + (w/4 - 1/4)

= 3 + (w - 1) / 4

Taking L. C. M

(12 + w - 1) / 4

(11 + w ) / 4

The expression that shows the distance Kane runs in a training session after w weeks will be; (11 + w ) / 4

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that the Initial miles kane plans to cover per session = 3 miles

The Increase in miles covered per session = 1/4 mile per week

Using the sum of an arithmetic progression formula to calculate the distance covered after w weeks

Tn = a + (n - 1) d

a = first term = 3 miles

n = nth term = number of weeks = w

d = common difference = the constant increase in distance per week = 1/4

Hence, after w weeks,

= 3 + (w - 1) × 1/4

= 3 + (w/4 - 1/4)

= 3 + (w - 1) / 4

= (12 + w - 1) / 4

= (11 + w ) / 4
