Answer:
x = -9, y = 6.
Step-by-step explanation:
-x + y = 15
-5x - 3y = 27
From the first equation:
y = x + 15.
Substituting for y in second equation:
-5x - 3(x + 15) = 27
-8x - 45 = 27
-8x = 72
x = -9.
Now plug x = -9 into equation 1
-(-9) + y = 15
y = 15 -9 = 6.
Answer: 3 4/5
Explanation: 19 divided by 5 is 3 4/5
Answer:
y=7
Step-by-step explanation:
It has to be go in the opposite direction and x=4 so the answer will have to be y=something and if the line has the point (5,7) then the line must be y=7
Not sure what 14 is asking?
15 would be 16.
The square root of width squared plus length squared equals the diagonal.
So if you just change the order of the equation you can find the length.
Double check it by doing it both ways to see if your answer is right.
Cavalieri's principle states that volume formulas for pyramids and cones will also apply to both right and oblique solids, a<span>s long as the "matching" cross section areas are equal.
So we can use the formula V=bh regardless of the resulting shape.
V = bh = </span>π(15 m)²(12 m) = 2700π m³ ≈ 8482.3 m³
