Hi can someone plss help me with this!!

Answer:

26

Step-by-step explanation:

The number of students in Regan's class will be 26.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Regan's class is preparing for a field trip. Her teacher purchased bottled water for the journey and asked Regan to stock a cooler with 2 bottles for every student who is going, 3 of the students didn't turn in permission slips and aren't going on the trip. So, Regan stocks the cooler with 46 bottles of water.

The number of students:-

46 / 2 = 23

23 + 3 = 26

Therefore, the number of students in Regan's class will be 26.

Answer: C

Step-by-step explanation: using Δx/Δy we find that the slope is -59. Since the y intercept is -176 using the plug in -235 = -59(1) + b, C is the only one that can match that answer.

7(b - 2) = -7

7b - 14 +7 =0

7b =14 + 7

7b =21

7b/7 =21/7

b = 3

Answer:

8.6 units

Step-by-step explanation:

use the distance formula:  d = [tex]\sqrt{(y-y)^2 + (x-x)^2}[/tex]

d = [tex]\sqrt{[(3-(-2)]^2 + (-3 - 4)^2}[/tex]

d = [tex]\sqrt{5^2 + (-7)^2}[/tex]

d = [tex]\sqrt{25+49}[/tex]

d = [tex]\sqrt{74}[/tex]

d = 8.6

Answer:

  x = ±3√2i

Step-by-step explanation:

Add -18 to both sides of the equation:

  x^2 = -18

Take the square root of both sides:

  x = ±√(-18)

Remember that 18=9·2 = (3^2)·2 and √-1 = i. Simplify.

  x = ±(√(3^2))·(√2)·(√-1)

  x = ±3√2i

Step-by-step explanation:

the slope = (4-0)/(-1-0) = 4/(-1) = -4

the equation : y = -4x

m = (Y2 - Y1)/(X2 - X1)

m = (0 - 4)/(0 - (-1))

m = -4/(0 + 1)

m = -4/1 = -4

[tex]\displaystyle \left \{ {{3=-10k + b} \atop {-8=-8k + b}} \right[/tex] [tex]\displaystyle \left \{ {{b= 3 + 10k} \atop {b=8k - 8}} \right \Longrightarrow 3 + 10k = 8k - 8[/tex]

[tex]3 + 10k = 8k - 8[/tex]

[tex]2k = -11|:2[/tex]

Answer:

What variable are you trying to solve? Imma just guess you are trying to solve for x since its on the left side so...

2x+3=r+2

Subtract three from both sides

2x=r-1

Divide 2 from both sides

x=r-1/2 OR

x=1/2r+-1/2

Answer:

1

Step-by-step explanation:

let x = smallest

let x+2 = middle

let x+4 = largest

x + x + 4 = 6(x +2) - 12

2x + 4 = 6x + 12 - 12

2x + 4 = 6x

4 = 4x

x = 1

numbers are 1, 3, 5

check:

is 1 + 5 equal to 6(3) - 12

6 = 18 - 12

6 = 6

Answer:

slope = 35/2

y intercept is 0

Step-by-step explanation:

the y-intercept is 0 because you can see from the graph that it intersect with y-axis at (0,0)

Slope = rise /run

pick a point (8, 140)

rise = 140

run = 8

slope = 140/8 = 70/4 = 35/2

Answer:

x = 47

Step-by-step explanation:

Because the lines are parallel, we know that some angles are the same, see the images attached. That means that A and B in the image are the same angles. So we know that angle A totals to 78 degrees. And the angle outside the triangle is 35. So the angle inside the triangle is

78 - 35 = 43.

The interior angles of a triangle add up to 180. We know that one angle is 43 and another angle is 90 because of the indicating square angle marker. That means that

43 + 90 + x = 180.

Then we can simplify the equation:

133 + x = 180⇒

x = 180 - 133⇒

x = 47

Answer: 280

Step-by-step explanation:

                                                  (-11 - 17) (2 - 12) = 280/1 = 280

Subtract: -11 - 17 = -28

Subtract: 2 - 12 = -10

Multiple: the result of step No. 1 * the result of step No. 2 = -28 * (-10) = 280
