Mrs brown is putting different colored sands into cups

Answer:

I think the answer is -40

Step-by-step explanation:

Answer:

x=0

Step-by-step explanation:

so we are going to first subtract by both sides,

x=80       y=60

  -20           -20

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

x=60     y=40

then again,

x= 60 y=40

  - 20    -20

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

x=40 y=20

and again,

x=40 y=20

 -20    -20

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

x=20 y=0

then lastly again,

x=20 y=0

 -20   -20

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

x=0   y=-20

Answer:

Ithink this would be 12/3

Step-by-step explanation:

12 blocks in total grouped into 3 groups.

The division problem shown here is 12 columns divided into a group of  3.

Using models, or pictures, can help to visualize and solve math problems. Models can include number blocks, in which a small square equals 1, a long rectangle equals 10, and a large square equals 100.

Given here are 12 columns arranged in 3 square boxes

thus the picture problem must be arranging 12 columns using 3 groups

therefore, 12÷3 = 4 columns

Hence, the division problem is arranging 12 groups in 3 groups of 4 columns in each group.

Answer:

[tex]\displaystyle\text{Slope: } -\frac{4}{3}[/tex]

Point (4,1)

Step-by-step explanation:

The Equation of the Line

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

The given line is:

[tex]\displaystyle y-1=-\frac{4}{3}(x-4)[/tex]

If we compare the equation of this line, both the slope and the point through which is passes are clearly identifiable:

Slope:

[tex]\mathbf{\displaystyle -\frac{4}{3}}[/tex]

Point (4,1)

Answer:

30*1 = 30 - 1st

30*2 = 60 - 2nd

30*3 = 90 - 3rd

30*4 = 120 - 4th

30*5 = 150 - 5th

Above are the first 5 multiples of 30.

Answer:

30,60,90,120,and 150. I hope this helps:)

Step-by-step explanation:

Answer:

y=mx+b is slope-intercept form

Ax+By=C is standard form.

IN y=mx+b, m represents the slope and B represents the y intercept.

To switch from standard form to slope-intercept form all we need to do is get y alone. thats it. By folowing these steps:

-6x+5y=-30

-6x+6x+5y=-30+6x - this cancels the x on the left side of the equation bringing us one step closer to getting y alone

5y=-30+6x

5y / 5=(-30+6x) / 5 -this last step leaves y alone and brings us to slope intercept form.

y=-6+30x

y=30x-6 - i switched the 30x and 6 because y=mx+b not y=b+mx

y=30x-6

SInce m represents the slope and b represents the y itnercept, 30 is the slope and -6 is the y intercept

30=m(slope)

-6=b(y-intercept)

Btw because the slope is 30 it means the line with point like so: / since it has a positive slope.

Hope this helps!

Answer:

The value of x is 5

The length of YZ is 5 units

Step-by-step explanation:

If a point lies on a line segment, then it divides it into 2 parts, the sum of their length equals the length of the line segment

Let us use this fact to solve the question

∵ Point Y is between points X and Z

→ By using the fact above

∴ XY + YZ = XZ

∵ XY = 4x and XZ = x

∵ XZ = 25

→ Substitute then in the equation above

∴ 4x + x = 25

→ Add the like terms in the left side

∴ 5x = 25

→ Divide both sides by 5 to find x

∵ [tex]\frac{5x}{5}[/tex] = [tex]\frac{25}{5}[/tex]

∴ x = 5

∴ The value of x is 5

∵ YZ = x

∵ x = 5

∴ YZ = 5

∴ The length of YZ is 5 units

Answer:

The central angle of the sector is 0.5 radian

Step-by-step explanation:

given;

radius of the circle, r = 80 mi

area of the sector, A = 1600 mi²

Area of sector is given by;

A = ¹/₂r²θ

where;

θ is the central angle (in radians) of the sector

[tex]\theta = \frac{2A}{r^2}\\\\\theta = \frac{2*1600}{80^2}\\\\ \theta = 0.5 \ radian[/tex]

Therefore, the central angle of the sector is 0.5 radian

The central angle (in radians) of the sector is 28.66 degrees

The formula for calculating the area of a sector is expressed as:

[tex]A = \theta/360 \times \pi r^2[/tex]

Given the following parameters

radius r = 80mi

Area of sector A = 1600mi²

Substitute the given parameters into the formula

1600 = Ф/360 * (3.14)(80)²

1600 * 360 = 20,096Ф

Ф = 576000/20,096

Ф =28.66 degrees

Hence the central angle (in radians) of the sector is 28.66 degrees
