Answer:
2.1375 bottles of paint
Step-by-step explanation:
cardboard length = 14 1/4 ft, which is equivalent to (4*14 + 1)/4 = 57/4 ft
cardboard width = 6 ft
Rectangular cardboard area = length * width = 57/4 * 6 = (57*6)/4 = 342/4 ft², which can be simplified dividing numerator and denominator by 2: 171/2 ft²
If 1 bottle of paint covers an area of 40 square feet, then to paint 171/2 square feet the following proportion must be satisfied:
1 bottle of paint / 40 square feet = x bottles of paint / (171/2) square feet
x = (1/40) * (171/2) = (1*171)/(40*2) = 171/80 or (160 + 11)/80 = 160/80 + 11/80 = 2 11/80 or 2.1375 bottles of paint
The word form of 3.4 is three and four-tenths. Expanded form is 3+.4.
Answer:
B. (-3, 5, 6)
Step-by-step explanation:
The system of equations is:
x + 3y - z = 6 ... (i)
4x - 2y + 2z = -10 ... (ii)
6x + z = -12 ... (iii)
The value of z in (iii) is;
z = -12 - 6x
Replacing z in (i) and (ii) gives:
x + 3y - (-12 - 6x) = 6 ... (i)
4x - 2y + 2(-12 - 6x) = -10 ... (ii)
Simplifying gives;
7x + 3y = -6 ... (i)
-8x - 2y = 14 ... (ii)
Multiplying (i) by 2 and (ii) by 3 gives;
14x + 6y = -12 ... (i)
-24x - 6y = 42 ... (ii)
Adding (i) and (ii) gives;
-10x = 30
x = -3
Replacing x = -3 in (i) gives;
7(-3) + 3y = -6
3y = 21 - 6
y = = 5
Replacing x = -3 in (iii) gives;
6(-3) + z = -12
z = -12 + 18 = 6
