Answer:
Divide the 1st equation by 2
a + 2c = 19
Divide the 2nd equation by 3
a + c = 13.5
Subtract the 1st equation and the 2nd equation
c = 5.5
Substituting back into the 2nd equation will give:
a + 5.5 = 13.5
a = 8
Step-by-step explanation:
Answer:
I believe 13 miles.
Step-by-step explanation:
Set up a ratio since it will be at the same pace.
9.75 miles/3 hours = x miles/4 hours
Cross multiply to solve for x.
9.75 (4) = 3x
39 = 3x
So x = 13 miles.
If you buy one photo op picture you can have as many people as you want. ( there is a limit of course but I don’t know what it is)
It depends on the person you’re taking the photo with but most of the time, yes you can
Because they have like-exponents (the exponents of the x is the same number, x^6) you can treat both values sort of like whole numbers. 512x^16 + 1x^16 making it 513x^16. Same thing with the y, it should be 1y^14+ 1y^14 = 2y^14
Cosine = adjacent / hypotenuse
So that means the adjacent side = 15 and the hypotenuse = 17
By Pythagorean Theorem, we know that
opposite^2 = hypotenuse^2 - adjacent^2
opposite^2 = 17^2 - 15^2
opposite^2 = 289 - 225
opposite^2 = 64
opposite side = 8
sine = opposite / hypotenuse
So,
sine A = 8 / 17
