If you add all of the digits of a number, and it's divisible by 3, the entire number will be divisible by 3. If the number is divisible by 2 and 3, it's divisible by 6 as well. If the digits of a number add up to a number divisible by 9, the whole number will be divisible by 9.

Ivan is painting 3 walls in his living room. Each wall measures 9 3/4 feet tall by 14 1/4 feet wide. Ivan needs to estimate the
Alenkinab [10]

Answer:

The estimated area is 416\frac{13}{16}\ ft^{2}

Step-by-step explanation:

we know that

To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3

step 1

Convert the dimensions to an improper fractions

9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft

14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft

step 2

Find the area of one wall

(\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}

step 3

Multiply the area of one wall by 3

(3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}

step 4

Convert to mixed number

\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}

Answer if you have a big brain 96 POINTS
nordsb [41]

Answer:

1) 2x+7

2) -3x+11

3) 0.75x-2

4) -2x+0

5) -1.5x+2

6) -4x+16

Step-by-step explanation:

1) y = mx + c

m = 2 when x=1 , y=9

9 = 2(1)+c

c = 7

y = 2x + 7

2) m = -3

When x=4, y= -1

-1 = -3(4) + c

c = -1+12 = 11

y = -3x + 11

3) m = 0.75

When x= -4, y= -5

-5 = 0.75(-4) + c

-5 = -3 + c

c = -2

y = 0.75x - 2

4) m = (y2-y1)/(x2-x1)

m = (2-(-6))/(-1-3) = 8/-4 = -2

y = -2x + c

When x= -1, y= 2

2 = -2(-1) + c

2 = 2 + c

c = 0

y = -2x + 0

5) m = (-10-(-4))/(8-4)

m = (-10+4)/4 = -6/4 = -1.5

y = -1.5x + c

When x= 4, y= -4

-4 = -1.5(4) + c

-4 = -6 + c

c = 2

y = -1.5x + 2

6) m = (-4-4)/(5-3) = -8/2 = -4

When x= 3, y= 4

4 = -4(3) + c

4 = -12 + c

c = 16

y = -4x + 16
