Answer:
Step-by-step explanation:
Let the number = x
So we are trying to work out what number must be subtract from the numerator and denominator of 5/3 to equal 5/7.
You can write this as:
Then you want to get rid of the fractions so multiply both sides by 3-x
Then multiply both sides by 7
Multiply it out.
35 - 7x = 15 - 5x
Add 7x to both sides:
35 = 15 - 5x + 7x
35 = 15 + 2x
Subtract 15 from both sides
35 - 15 = 2x
20 = 2x
To find x, divide both sides by 2.
x = 10.
Answer:
Step-by-step explanation:
sin (2x+14)=cos(x-5)
or 2x+14+x-5=90
3x=90-9=81
x=81/3=27°
Speed = Distance ÷ Time
Distance = 2797.2
Time = 0.15
2797.2 / 0.15 = 18,648
Speed = 18,648
