Answer:
The number of adults, a, is 300, and the number of kids, k, is 200.
Step-by-step explanation:
k + a = 500 (1)
3k + 10a = 3,600 (2)
Multiply both sides of equation (1) by -3.
(k + a) • -3 = 500 • -3
-3k − 3a = -1,500
Now, add this equation to equation (2).
3k + 10a = 3,600
+ -3k − 3a = -1,500
7a = 2,100
a = 300
Substitute the value of a into equation (1).
k + a = 500
k + 300 = 500
k = 500 – 300
k = 200
In the system of equations, a represents the number of adults and k represents the number of kids who visited the carnival. The number of adults, a, is 300, and the number of kids, k, is 200.
$1.32 ÷ 12 ounces = $0.11 per ounce
$0.11 x 16 ounces = $1.76
A 16 ounce lemonade is $1.76.
Answer: The Area is 35 square centimeters.
Key:
B1 = Base #1
B2 = Base #2
H = height
* = multiply
/ = divide
Step-by-step explanation:
First, write down the formula needed: (B1 + B2) * H / 2 = Area
Now Fill in what you know:
(6 + 8) * 5 / 2 = Area
B1 is 6 cm
B2 is 8 cm
The Height is 5cm (TIP: the height is usually in a vertical direction).
&
The Area is still unknown
Let’s Answer the equation now:
(B1 + B2) * H / 2 = Area
(6 + 8) * 5 / 2 = Area
(14) * 5 / 2 = Area
70 / 2 = Area
Area = 35 square centimeter (cm).
