What is 0.3x-2 equal

Answer:

70 degrees

Step-by-step explanation:

Since the angles of a triangle have to add up to 180 degrees, you know that the third angle of the triangle on the left would be 180 - 60 - 65 = 55 degrees. Then, since the angles on a straight line have to add up to 180 degrees you could find one of the two missing angles of the second triangle by doing

180 - 55 - 50 = 75.

Then, you have 2 out of the 3 angles of the triangle on the right and you can find the third, the ?, by doing 180 - 75 - 35 = 70 degrees

Answer:

30 gallons (that’s a lot of tea!)

Step-by-step explanation:

Hi there!

we know that there are 60 minutes in an hour, 120 in 2 hours.

If 4 cups are poured every minute, we multiply 4 by the number of minutes in 2 hours, 120.

now we have 480 cups. However, they asked for gallons. They already give how many cups are in a gallon, 16, so all we have to do is divide 480 by 16 to find the amount of gallons needed.

480/16 = 30 gallons!

I hope this helped!

Answer:

30 gallon

Step-by-step explanation:

first you count up how many minutes is in 1 hour mutilply it by 2 if 4 cups were poured every minute and there's 16 cups per gallon you take 120 being 2 hours in minutes take 120 multiply it by 4 bc that's how man cups are poured per minute and that 480 cups 480 cups divided my 16 which is how many cups is in a gallon and you get 30

Answer:

y= 20x +30

Step-by-step explanation:

y - intercept of the graph is 30

Slope of the graph is [tex]\frac{20}{1}[/tex]

Answer:

y = 20x + 30

Step-by-step explanation:

y=mx+b

b value = y-intercept, so you find where the line crosses the y-axis.

Find point at (0,30); b = 30

m value = rise/run (rise over run) (y/x)

find the next point that the graph intersects at and count add to it to find 30.

the closest point is at (-1,10)

go back to rise/run

30-10 = 20

0-(-1) = 1

20/1 =20 is your m value

plug m value and b value into equation to form your line.

y=20x+30

Answer:

x=6

Step-by-step explanation:

Solve for x.

5x-15 = 2x+3

(Move the 2x to the other side of the equation.)

3x-15= 3

(Move the 15 to the right side of the equation.)

3x=18

(Divide both sides by 3 to isolate the variable.)

x=6

Step-by-step explanation:

3/8x-1/3x+6=x

(3(3x)-1(8x))/24=x-6

(9x-8x)=24(x-6)

x=24x-24×6

x=24x-144

144=24x-x

23x=144

x=144/23

Step-by-step explanation:

log3(3^4) = x.

=> 3^x = 3^4

=> x = 4.

7.06 Please Mark Me Brainliest

Step-by-step explanation:

Answer:

the difference is 7.06

Step-by-step explanation:

16.3-9.24=7.06

The time taken that should be rapidly are distinct 3 seconds later should be considered as 24.78 m/s.

Here the point should be considered directly under the center of the bridge as the origin

Here

x = 20t, y = 15t, z = 10

let us assume s be the distance between them at time t,

So it be like

[tex]s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100[/tex]

2s ds/dt = 1250t

ds/dt = 625t/s

Now at the time when

t = 3,

[tex]s = \sqrt (625*9+100)[/tex] = 75.6637

So,

ds/dt = [tex]625*3/75.6637[/tex] = 24.78 m/s

Answer:

(0,-5)

Step-by-step explanation:

In y = mx+b, b is the y-value of the y-intercept.

Here, b = -5.

Note: the y-intercept is a POINT, not a value.

Step-by-step explanation:

Hey there!

Given equation is; y= 3x-5.

Comparing the equation with y= mx+b, where "b" is y-intercept. we get;

y-intercept= -5

Therefore, y-intercept of the equation is"-5".
