Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.
-5x + y = 13 ⇒ y = 5x + 13
Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :
-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3
Simplify and solve for x :
-3x + 15x + 39 = 3
12x = -36
x = -3
Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give
-3 (-3) + 3y = 3
9 + 3y = 3
3y = -6
y = -2
So the solution to the system of equations is (x, y) = (-3, -2).
Answer:
All you do is just multiply them.
Step-by-step explanation:
5a^2 b^4(3ab^3)^2=
45(a^(4))(b^(10))
For your answer you would get 1.40 dollars as your answer or B
Answer:
the length of the stripe is 20.82inches
Step-by-step explanation:
given
height of can = 5in
circumference = 12in
π = 3.142
the circumference of the base = 2πr = 12
radius of base = 1.91in
if the stripe wind once round the can (circumference length), it will start from the radius base to the radius top.
the total length of the stripe = 2radius + circumference of can + height
= 2(1.91) + 12 + 5 = 20.82inches
