Mr. Torres spent $40.00 to buy 18 pounds of ground beef and chicken for a family to cook out. If the price of ground beef was $4.00 per pound and the chicken was $2.00 per pound, how many pounds of each did he buy?
Answer:
They bought 2 pounds of ground beef and 16 pounds of ground chicken.
Step-by-step explanation:
Let b be the beef, and c be the chicken:
b + c = 18, the pounds of beef and the pounds of chicken added equal 18 pounds
4b + 2c = 40, the beef costs 4 dollars per pound and the chicken costs 2 dollars per pound. They add up to 40 dollars total.
Use the equation b + c = 18 and subtract c from both sides to get b = 18 - c. We replace this equation with b in 4b + 2c = 40 to get 4(18 - c) + 2c = 40 because b is 18 - c.
Now we solve for c:
4(18 - c) + 2c = 40
Simplify:
72 - 4c + 2c = 40
Combine Like Terms:
72 - 2c = 40
subtract 72 from both sides:
-2c = -32
Divide Both Sides by 2:
-c = -16
Make the Equation Positive:
c = 16
Okay cool, now we know that they bought 16 pounds of chicken, to find out how much beef the bought, replace c by 16 in b + c = 18 to get b + 16 = 18
b + 16 = 18
Subtract 16 from both sides:
b = 2, they bought 2 pounds of beef
To check, replace c with 16 and b with 2 in 4b + 2c = 40 to get
4(2) + 2(16) = 40
Multiply:
8 + 32 = 40
40 = 40
The equation is true

The radius of a circle is 3 feet. What is the circumference?
Circumference = 2 * pie * radius
Geometry
Answer:
19 feets
Step-by-step explanation:
Given that , the radius of the circle is 3 feet . We need to find the circumference.
We know that the circumference of circle is 2πr . So ,=> C = 2 π r
=> C = 2 × 22/7 × 3ft
=> C = 18.84 ≈ 19 ft
Hence the circumference of the circle is 19 feet.Answer:
B
Step-by-step explanation:
circumference = 2πr
3.4x 2 x 3 = 18.84

PLEASE HELP ANSWER ASAP
Answer:
x = 20
Step-by-step explanation:
Use Pythagorean Theorem to solve for x:
a^2 + b^2 = c^2
Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)
12^2 + 16^2 = x^2
(12*12) + (16*16) = x^2
144 + 256 = x^2
400 = x^2
Take square root of both sides to solve for x
sqrt(400) = sqrt(x^2)
20 = x or x = 20
