There is one solution in the system of equation
<h3>How to determine the number of solutions?</h3>
The system of equations is given as:
8x=12y-9 and 27y+18x=21
Divide 8x=12y-9 by 8
x = 1/8(12y-9)
Substitute x=1/8(12y-9) in 27y+18x=21
27y + 18 * 1/8(12y-9) =21
Expand
27y + 27y - 20.25 =21
Evaluate the like terms
54y = 41.25
Divide by 54
y = 0.7639
Hence, there is one solution in the system of equation

Correct answer is C.
Suppose the length of the edge of a cube is 1.
CQ = 1 and
Answer:
16
Step-by-step explanation:
The square numbers are
1² = 1
2² = 4
3² = 9
4² = 16 ← this is the closest perfect square
5² = 25 (not applicable, over 22)
Answer:
x = 200.674
Step-by-step explanation:
tan∅ = opposite/adjacent
Step 1: Find length of <em>z</em>
tan70° = 119/z
ztan70° = 119
z = 119/tan70°
z = 43.3125
Step 2: Find length <em>z</em> + <em>x </em>(denoted as <em>y</em>)
tan26° = 119/y
ytan26° = 119
y = 119/tan26°
y = 243.986
Step 3: Find <em>x</em>
y - z = x
243.986 - 43.3125 = x
x = 200.674
Sorry for taking so long but x equals 8!
