Answer:
Step-by-step explanation:
Let x and y represent the weights of the large and small boxes, respectively. The problem statement gives rise to the system of equations ...
x + y = 85 . . . . . combined weight of a large and small box
70x +50y = 5350 . . . . combined weight of 70 large and 50 small boxes
We can subtract 50 times the first equation from the second to find the weight of a large box.
(70x +50y) -50(x +y) = (5350) -50(85)
20x = 1100 . . . . simplify
x = 55 . . . . . . . divide by 20
Using this in the first equation, we can find the weight of a small box.
55 +y = 85
y = 30 . . . . . . . subtract 55
A large box weighs 55 pounds; a small box weighs 30 pounds.
The formula of the area of the circle:
π × radius^2
In this case, given that the radius is 14 inches:
π × 14^2
=196π square inches
Therefore the answer is 196π square inches.
Hope it helps!
Alright. So the problem is
10*12+-15/5+2(9-4)
Lets break down what we can for now
First focus on parenthesized, multiplying, and dividing in the problem.
10*12=120 15/5=3 (9-4)=5
120+-3+2*5
So the next step, we see 2*5 and a negative -3 on top of a positive symbol.
2*5=10
120-3+10
Now subtract from the left to the right and get your answer.
120-3=117
117+10=127
