I'm not quite sure how you got your answer, but the answer to c is 57 tiles.


First we can find the area of a singular tile by multiplying 12 and 12 together to get 144 in².


Then we find the area of the kitchen floor by splitting it into two rectangles, finding those areas, and adding them. This gives us (108 × 60) + (48 × 36) = 6,480 + 1,728 = 8,208 in².


Then to find how many tiles fit, we need to divide the total area, 8,208 in², by the area of a singular tile, 144 in², which results in 57 tiles.


I hope this helps!

Which of the following linear systems has a solution <br> (5,0)<br> SOMEONE PLS HELPPP
Korvikt [17]

Answer:

D

Step-by-step explanation:

out of the choices

A) 2x-y=-2

3x+2y=-10

B) x+4y=3

2x+5y=3

C) 2x+3y=5

x-4y=-14

D) 3x+4y=15

x+y=5

only the system in D has a solution of x=5 and y=0

solve by substitution x+y=5 so x=5-y

plug into the other equation so 3(5-y)+4y=15

distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms

so y=0 then put that value back into the other equation

so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)

Hope this helps! :)

Help please now i cant figure it out
12345 [234]

Answer:

a. \frac{-11}{24}

b. \frac{-3}{2} \\

c. \frac{31}{7}

d.  \frac{11}{16}

11, 3, 31, 11 = code

Step-by-step explanation:

a. \frac{-1}{6}\\ * 2\frac{3}{4} =

2\frac{3}{4} = \frac{4*2+3 }{4}=  \frac{11}{4}

\frac{-1}{6}\\ * \frac{11}{4} = \frac{-1*11}{6*4} = \frac{-11}{24}

b.  \frac{3}{16} / \frac{-1}{8} =

\frac{3}{16} * \frac{8}{-1} = \frac{3*8}{16*-1} \\ = \frac{24}{-16} = \frac{-3}{2} \\

c. \frac{-31}{56} * \frac{-8}{1} = \frac{31}{7} (you can reduce 8 & 56 by dividing by 8: 56/8=7 & -8/8= -1)

d. 1 \frac{7}{8} / 2\frac{8}{11} =

1 \frac{7}{8} = \frac{8*1+7}{8} = \frac{15}{8}

2\frac{8}{11} = \frac{11*2+8}{11} = \frac{30}{11}

\frac{15}{8} * \frac{11}{30} = \frac{11}{16} (you can reduce 15 & 30 by dividing by 15: 15/15=1 & 30/15 = 2)

1. Evaluate each expression when x = -2 and y = 3.
borishaifa [10]
a) 3(-2) + 4(3) = -6 + 12 = 6

b) 2(-2) -3(3) +5 = -4 -9 + 5 = -8

c) 4(-2) -(3) = -8 -3 = -11

d) -(-2) -2(3) = 4 -6 = -2

e) (1/2)(-2) +(3) = -1 +3 = 2

f) (2/3)(3) -(1/2)(-2) = 2 + 1 = 3
