Answer:
The value of x is 8/5
Step-by-step explanation:
(35/6)x + (8/3) = 12
(35/6)x = 28/3 (cross multiplication)
105x = 168
x = 8/5
<span>We have lateral faces that are rectangles and 2 congruent polygons that are bases. This must be 3-dimensional solid figure - quadrilateral prism. If those 2 bases are squares then it is a rectangular prism, but the bases also can be 2 rhombuses. Answer: Quadrilateral prism.</span><span />
length = 8ft
height = 4 in
width = w ft --> u looking for this
convert in to ft for the height:
4 in (1 ft / 12 in) = 1/3 ft
You know that:
1 cubic yard = $ 98
? cubic yard = $58.07
Solve for ? cubic yard:
? cubic yard = 58.07/98 = 0.592551
convert this in cubic feet:
1 yard = 3 feet
0.59255 cubic yard (27 cubic ft/1 cubic yard) = 15.99887755 cubic ft
Now solve for the width:
length x width x height = ? cubic ft.
width = ? cubic ft / (length x height) =15.99887755 cubic ft/[(8ft)(1/3 ft )] = 5.999579082 ft
approx 6 ft
So first we want to assign the certain number a variable, let's say x.
So we can write this out as an equation, or:
7x + 12 = 47
Now we can just solve this.
7x + 12 - 12 = 47 - 12
7x = 35
/7 /7
x = 5
So the certain number is 5.
