Answer:
The answer is C because how much each girl paid for each pound of cherries has the variable C attached, and the rest of the money spent added to it. Also looking in the equation the sign tells us that they paid the same price for everything totaled in all.
answer:
x = 0.80
y = 1.50
step-by-step explanation:
x = cost of tacos
y = cost of burritos
both equations:
3x + 2y = 5.40
2x + 1y = 3.10
^
turn this | into this |
v
y = 3.10 - 2x
then add it to the equation :
3x + 2 [ 3.10 - 2x ] = 5.40
3x + 6.2 - 4x = 5.40
-1x = - 0.8
x= 0.80
then add x = 0.80 to the equations to get :
3 [ 0.80 ] + 2y = 5.40
2.4 + 2y = 5.40
2y = 3
y = 1.5
Answer:
0 or undefined
Step-by-step explanation:
As you said, it could be anything, and there is proof that could be anything, which I'm sure your teacher would appreciate (writing proofs is a level of mathematical achievement that only hardcore math nerds can do, and it'd be super cool if you could write one yourself) A proof is basically a written mathematical description of exactly why something is the way it is.
But if you want to choose just one answer, I'd choose either 0 or undefined. If the answer is something that's bubbled in, then choose 0.
In the simplest assumed equation f(x) = 1 + x, x would have to = 0.
If we're looking at this graphically, y=1 (remember y=f(x)) graphed is a straight line that never crosses the x axis, which would mean there's no possible x value that would work for that equation.
Also, depending on what level math you're in, you may not even be working with undefined answers yet, in which case, your best answer would again be 0.
Hope this helped!
Answer:
B. 171.74 cm²
Step-by-step explanation:
Area of a sector = 
.
Where,
radius (r) = 8.7 cm
Plug in the values into the formula
Area of sector = 
Area of sector = 
Area of sector = 171.74 cm² (approximated)
