Answer: x=8.56365
Step-by-step explanation:
You have the angle and hypotenuse and have to find the opposite so you use sin.
Sin#=o/h
Sin35=o/20
Then I just put that into my calculator and got x= 8.56365. (I added the decimals cause idk what you need to round to)
<span>Multiply
the 1st equation by 5 and multiply the 2nd equation by 2. This will
eliminate the x's when you add the two new equations together.
</span>
<span>A) −2x+3y=8
B) 5x+4y=10
So we multiply A) by 5 and B) by 2
</span><span>A) −10x+15y=40
B) 10x+8y=20
</span>
Adding the equations:
23y = 60
y =

Three times = 3 ×
<span>The difference of 65 and 48 = 65 - 48 = 17
(Difference = subtract)
That equals 3 </span>× 17
<span>
Answer = 3 </span>× 17
<span>(3 </span>× 17 = 51)<span>
Hope this helped☺☺

Answer:
20times
Step-by-step explanation:
A fair of die has 6sides.
If 4 appears 'once' out of a 6.
Then, 4 will appear 2times out of 12 i.e
6faces = 1time
12faces = 2times.
But remember that we want to know how many times 4 will appear out of a 120
120faces = x times
Since 6faces = 1time (i.e 4 occur one time in six faces)
cross multiplying:
6 × x = 120
x = 120/6
x = 20times
This means 4 will appear 20times out of a 120
