Answer:
3.5x
Step-by-step explanation:
Put into numbers, [4*x+(3x)]*1/2. You cant completely solve for x in this, as we would need an answer with no variable. But, 4*x=4x, and 4x+3x=7x because we would need to combine like terms. But you still need to cut it in half. Half of 7x is 3.5x, so there ya go!
Answer:
1794
Step-by-step explanation:
598
× 3
-------
1794
Part A)
we know that
<span>scale ----------> inch/4 feet=0.25 in/ft
</span>[scale]=[scale drawing]/[actual]
[actual]=[scale drawing]/[scale]
for <span>length --------> 4 1/2 in ---------> 4.5 in (</span>scale drawing)
[actual]=[4.5]/[0.25]=18 ft
for <span>width ---------> 3 3/8 in</span> ---> (3*8+3)/8 ---> 27/8 in (scale drawing)
[actual]=[27/8]/[0.25]=13.5 ft
the answer part A is
length actual <span>kitchen floor is 18 ft
</span>width actual kitchen floor is 13.5 ft
Part B)
the area of one square in the actual=(1/2)*(1/2)=0.25 ft²
total area gray tiles=0.25*14=3.5 ft²
total area white tiles=0.25*10=2.5 ft²
find <span>how many tiles 2 in by 2 in of each color will he need
1ft</span>²-------------> 144 in²
gray tiles
3.5 ft²---------------> 3.5*144=504 in²
[tiles 2 in by 2 in gray]=504/(2*2)=126 gray tiles
white tiles
2.5 ft²---------------> 2.5*144=360 in²
[tiles 2 in by 2 in white]=360/(2*2)=90 white tiles
the answer Part B) is
126 gray tiles
90 white tiles
Answer:
Reduce the greatest common factor on both sides of the equation: (2x+y=12
(x-3y=27
Rearrange like terms to the same side of the equation: (2x+y= 12
(x=27+3y
Substitute into one of the equations: 2(27+3y)+y=12
Apply Multiplicative Distribution Law: 54+6y +y=12
Rearrange unknown terms to the left side of the equation: 6y+y=12-54
Combine like terms: 7y=12-54
Calculate the sum or difference: 7y=-42
Divide both sides of the equation by the coefficient of variable: y= -42÷7
Calculate the product or quotient: y= -6
Substitute into one of the equations: x=27+3×( -6)
Remove the parentheses: x=27-3×6
Calculate the product or quotient: x=27-18
Calculate the sum or difference: x=9
The solution of the system is: x=9
y=-6
Answer:
x=9
y=-6
