Answer:

x=3

Step-by-step explanation:

3(2X-7)=5-(1-X)

6X-21=-5-1+X

6x-x=-5-1+21

5x=21-6

5x=15

x=3

Answer:

3/5

Step-by-step explanation:

When you are given an x-intercept, the y value will always be 0.

When you are given a y-intercept, the x value will always be 0.

With the intercepts we are given, we can make two points we can solve for the slope with.

(5, 0)

(0, -3)

Now, find the slope with the formula [ y2-y1/x2-x1 ]

-3-0/0-5

-3/-5

3/5 or 0.6

Since you did not give any multiple choice options, here is a problem that is equivalent, because I divided the whole problem by 3, making it exactly equal to the other problem in size.

Answer:

37

Step-by-step explanation:

3x + 8x + 4x = 6x + 63 ( combine like terms)

>15x = 6x + 63 (subtract from both sides)

-6x. -6x

-----------------

>9x = 63. (divide both sides by 9)

Answer:

15/4

Step-by-step explanation:

Equation: 40(5+x)=70*5+0x

Solve:

200+40x=350

40x=150

x = 15/4

15/4 gallons is the answer.

3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the amount of water in galloons needed to be added to make 40% sugar. Hence:

40% of (x + 5) = 70% of 5

0.4x + 2 = 0.7 * 5

0.4x = 1.5

x = 3.75

Therefore 3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

Answer:

102°

Step-by-step explanation:

(3x - 12)° + (2x + 2)° = 180°

5x - 10 = 180 ⇒ x = 38

m∠A = (3x - 12)°

m∠A = (3×38 - 12)° = 102°

Answer:

∠a = 3x -12 ( Being corresponding angle)

Now

(3x-12) + (2x + 2) = 180 ( Sum of straight angles)

5x - 10 = 180

5x = 190

x = 38

m∠a = 3x -12 = 3*38 -12 = 102

Answer:

11.57142857 (it doesn't go in evenly)

the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.

When dividing 81 by 7, we can determine how many times 7 can be subtracted from 81 without going into negative values. By repeatedly subtracting 7 from 81, we find that 7 can be subtracted 11 times before reaching 4, which is less than 7. Therefore, the quotient is 11. However, there is a remainder of 4 left over.

So, the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.

Answer: -4x^2

Step-by-step explanation:

Step-by-step explanation:

(1) Create a table containing a few values of x and y

y - 3 = ½(x + 2)

   y = ½(x + 2) + 3

x     y

-10    -1

-6      1

0      3

6      7

10     9

(2) Plot your points

Draw dots at the coordinates of each point.

(3) Draw the graph

Draw a smooth line through the points.

Extend the line in both directions to the edges of the plot area.

Your graph of y - 3 = ½(x+2) should look like the figure below.
