A surfboard rental shop has 3 sizes of surfboards: 9 foot, 7 foot, and 5 foot. A few boards are lying on the sand end to end outside the shop. What is the exact distance that 2 large, 2 medium, and 3 small surfboards will stretch? Complete the blanks within the equation and solve.
S = 2 x __ +___ x 7 + 3 x ___
S = 2 x 9 + 2 x 7 + 3x 5
S = 18 + 2 x 7 + 3 x 5
S = 18 + 14 + 3 x 5
S = 18 + 14 + 15
S = 32 + 15
S = 47 feet
A honeybee travels 15 miles per hour, and its wings beat 200 times per minute. If a bee travels 45 miles, how many times will its wings beat? Complete the blanks within the equation and solve.
B = (___ X 60) x (45 ÷ ___)
B = (200 x 60) x (45 ÷ 15)
B = 12,000 x (45 ÷ 15)
B = 12,000 x 3
B = 36,000 times
Each cheese pizza is made with 9 ounces of mozzarella and 3 ounces of parmesan. Each meatball sub is topped with 2 ounces of romano cheese. What is the exact amount of combined cheeses used if an order consists of 4 pizzas and 5 meatball subs? Complete the blanks within the equation and solve.
c = 4 x ( ____+ ____) +____ x 2
4 x (9 + 3) + 5 x 2
4 x 12 + 5 x 2
48 + 5 x 2
48 + 10
58 ounces of cheese
A surfer receives a gift certificate to a surf shop for $100. She used the exact value of her card to buy a wet suit for $75, board wax for q, and 2 bottles of sunscreen for $6 each. Write and solve an equation to determine the exact value of q.
$75 + $6 x 2 + q = $100
$75 + $12 + q = 100
$87 + q = $100
q = $100 - $87
q = $13
A bee makes Z trips to and from the colony each hour to the nectar source that is 150 meters away. After 1 hour, the bee has traveled a total of 750 meters. Write and solve an equation to determine the value of Z.
150 x Z = 750 or Z = 750 ÷ 150
750 ÷ 150 =Z
Z = 5
5 trips
A large batch of Italian salad dressing is made daily. The liquid components of the dressing are 10 cups of olive oil, v cups of red vinegar, and 2 cups of cider vinegar for every gallon of dressing. Every day, the customers use 5 gallons of dressing. How many cups of red vinegar does the cook need to prepare enough dressing for 1 day? Hint: There are 16 cups in 1 gallon.
Equations may vary. Sample equation:
10 + v + 2 = 16 cups
12 + v = 16
v = 16 - 12
v = 4
4 cups per gallon x 5 gallons/day = 20 cups/day 20 cups of vinegar
