Answer:
NO IF 14 POUND BURGERS
NO IF 1/4 POUND BURGERS
Step-by-step explanation:
2 3/8 POUNDS < 10
10- 2 3/8 = 7 5/8 REQUIRED TO MAKE 10 1 POUND BURGERS
If 1/4 pound burgers then you can just divide 1/4 into 2 3/8
= 2 3/8 / 1/4 = 9.5 BURGERS = No
Because 10-9.5 = 0.5 burger required
1/2 burger is not equivalent to 1 whole burger.
Formatting first:
Step 1: (6.2 − 1.6) − 4.4 + 7.8
Step 2: 6.2 + (− 1.6 − 4.4) + 7.8 (commutative property)
Step 3: 6.2 − 6 + 7.8
Step 4: −14 − 6 = 8 (commutative property)
Step 5: 14 − 6 = 8
Step 2 is the associative property (a+b)+c=a+(b+c)
Step 4 is just wrong with -14 instead of 14; seems corrected in step 5.
Answer: He wrote commutative instead of associative in Step 2.
Answer:
B. 11
Step-by-step explanation:
Set up a system of equations where a is the number of adults and c is the number of children
a + c = 87
8a + 5c = 468
Solve by substitution by rearranging the first equation, then substituting it in the second equation:
a = 87 - c
Substitute this for a in the second equation, then solve for c:
8(87 - c) + 5c = 468
696 - 8c + 5c = 468
696 - 3c = 468
-3c = -228
c = 76
Then, plug this into the first equation to solve for a:
a + c = 87
a + 76 = 87
a = 11
So, 11 adults attended the carnival.
The correct answer is B, 11
Answer:
See below
Step-by-step explanation:
Volume of cylinder ( the pool) = pi r^2 h
V = pi (12^2)(4.5) = NOTE: <u>RADIUS</u> not DIAMETER
2035.75 ft^3
2035.75 ft^3 * 7.48 gal / ft^3 = 15 227.42 gals
15 227.42 gal * $.02 / gal = $ 304.55 to fill
<u />a=2
2a=2*2=4 (replace a with 2)
The answer is 4.
