(25,12)
(30,22)

$\\ \tt\hookrightarrow m=\dfrac{22-12}{30-25}$

$\\ \tt\hookrightarrow m=10/5$

$\\ \tt\hookrightarrow m=2$

Let the hall be A=1. For 3 hours 16 people can decorate the hall. Then P1=A\(t1.number people1) P=1/48. That is for 1 person. You have 24 people to decorate the same hall. Their P2 will be (1/48).24=1/2. t2=A/P2=2 hours

Solve the equation. Check your answer.<br> 6x - 3= 5x +5<br> X=

ZanzabumX [31]

Answer:

x = 8

Step-by-step explanation:

6x - 3 = 5x + 5

Move variable to the left hand side and change their sign.

$\sf \: 6x - 5x - 3 = 5$

Calculate like terms.

x - 3 = 5.

Move constant to the right hand side and change their sign.

x = 5 + 3
x = 8

<u>Check our answer :-</u>

6x -3 = 5x + 5

plug the 8 as x.

6 ( 8 ) - 3 = 5 ( 8 ) + 5
48 - 3 = 40 + 5
45 = 45

LHS = RHS

1/2,1/3,1/8 find the sum

Zarrin [17]

Answer:

23/24

Step-by-step explanation:

To find the sum you must ad.

Fractions can only be added and subtracted when the denominators (the bottom numbers) are the same.

24 is the smallest number that 2, 3 and 8 go into.

1/2 = 12/24, 1/3 = 8/24, 1/8 = 3/24

$\frac{12}{24} + \frac{8}{24} + \frac{3}{24} = \frac{23}{24}$

23/24

I need help with all three letters. thank u

creativ13 [48]

Answer:

Step-by-step explanation:

A to C

y = b + mx

b = y-intercept

m = slope of line

Looking at the line, the line crosses the y-axis at the coordinates (0,0). This means that the y-intercept is 0.

The slope formula is m=(y2-y1)/(x2-x1). Using the points on the line (-1, -3) and (1,3) we find that the slope is, 3.

Looking back we can see that our variables now have value so we can plug them into our formula.

y = b + mx

b = 0

m = 3

Substitute

y = 0 + 3x
