First off, turn 7 1/4 into a mixed number, 29/4. change 29/4 / 5/6 into a multiplication question by flipping 5/6 into 6/5 (AKA multiplying by the reciprocal) so you get 29/4 X 6/5. then multiply so you get 174/20. Next, simplify into a mixed number by seeing how many times 20 goes into 174, and then putting the leftovers into a fraction, so you get 8 14/20, then simplify even further so you get 8 7/10.
Answer:
8 bags of pretzels
Step-by-step explanation:
Let x represent the number of bags of pretzels Tim buys. We assume he spends exactly $20 on exactly 12 bags of snack food. Then his purchase is ...
1.50x + 2.00(12-x) = 20.00
-0.50x +24.00 = 20.00 . . . eliminate parentheses, collect terms
-0.50x = -4.00 . . . . . . . . . . .subtract 24
x = 8 . . . . . . . . . . divide by -0.50
Tim will buy 8 bags of pretzels.

True or False
The above numeral can be split as follows:
X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:
In Roman numerals;
Substitute 40 for XL and 4 for IV.
Hence;
<em /><em> is false</em>
Answer:
a+7
Step-by-step explanation:
2 + 5 = 7
7+a or a+7
Multiply each term in the parenthesis by -4
-4 • 6n-4•(-5)+3a
Calculate the product -4•6n= -24n
Multiply the numbers -4•(-5)= +20
Then put every thing together
Final Answer: -24n+20+3a
