oh I see. that's an interesting question but the problem is I hate maths
Answer:
x = 2
y =7
Step-by-step explanation:
the system of linear equation will be solve using substitution method,
let
Y=3x+1.............................................. equation 1
Y=2x+3.............................................. equation 2
substitute equation 1 into equation 2
3x + 1 = 2x + 3
combine the like terms
3x+1 -2x = 3
x = 3 -1
x = 2
put the value of x=2 in either equation 1 or 2
Y=2x+3.............................................. equation 2
y = 2(2) + 3
y = 4 + 3
y = 7
Answer:
x = 2
Step-by-step explanation:
63x - 1 and 62x + 1 are corresponding angles and congruent, thus
63x - 1 = 62x + 1 ( subtract 62x from both sides )
x - 1 = 1 ( add 1 to both sides )
x = 2
Answer:
Step-by-step explanation:
<em>m∠D</em> = 90° - 51° = <em>39°</em>
sin E = 
⇒ DE = DF × sin E
<em>DE</em> = 18 sin51° ≈ <em>14.0 ft.</em>
cos E = 
⇒ EF = DF × cos E
<em>EF</em> = 18 × cos51° ≈ <em>11.3 ft.</em>
The answer should be true
