Let's have B stand for burgers, and F stand for fries.
2.05B+0.85F=$19.10 - This equation is set equal to total price.
B+F=14 - This equation is set equal to total number of items.
Subtract the F in the bottom equation.
B=14-F
Put this in place of B in the first equation.
2.05(14-F)+0.85F=19.10
Make sure you distribute the 2.05 properly, over both the 14 and the F.
28.7 - 2.05F+0.85F=19.10
Collect like terms for the F values.
28.7 - 1.2F=19.10
Subtract 28.7 from both sides.
-1.2F=-9.6
Divide by -1.2 on both sides.
F=8
Put this value in place of F in either equation.
B+8=14
B=6
So F=8 and B=6.
Answer:
Mr. Miles’s statement is NOT reasonable
Explanation:
If Mr. Miles uses 2 1/10 pounds of clay for each model, Mr. Miles will have used a total of 6.3 pounds of clay.
The decimal form of 7 7/8 is 7.875, so 7.875 minus 6.3 will give you the amount of clay Mr. Miles has left over.
7.875 - 6.3 = 1.575
This means that Mr. Miles statement is not reasonable, as he only has about 1.6 pounds of clay left, not 3.
The answer is: [B]: " 3.99 * 10⁻⁶ " .

Note:
______________________________________________
We are given the following answer choices, and we are asked which one is the "smallest number" :
_______________________________________________
[A]: 4.4 * 10⁻⁵
_________________________________________
[B]: 3.99 ⋅ 10⁻⁶
______________________
[C]: 2.6 ⋅ 10²
______________________
[D]: 1.85 ⋅ 10³
_______________________
We can rule out answer choices: [C] and [D]; since these values, essentially "direct us" to move the decimal point FORWARD "2 places" and "3 places", respectively; whereas choices [A] and [B] essentially "direct us" to move the decimal point BACKWARD "5 places" and "6 places" respectively. Note that all values given in the answer choices are written in proper "scientific notation" —that is, beginning with a "single integer followed by (a) decimal point(s) and then additional digits (when needed). So, the answer choice that essentially "directs us" to move the decimal point BACKWARD "6 places" —

→ Answer choice: [B]: " 3.99 * 10⁻⁶ " ;

is the smallest value ; and as such, the correct answer.

60% of student don't buy a hot lunch.
The simple way of doing it is by taking both numbers and dividing them. 24 divided by 40= 0.6 Since percents are part of a whole, we need to multiply by 100 0.6 times 100 equals 60.
Easy and accurate.
Answer:
-12
Step-by-step explanation:
Let "integer" = x
When x is multiplied by 8, it equals -96:
8x = -96
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Divide 8 from both sides
(8x)/8 = (-96)/8
x = -96/8
x = -12
-12 is your answer
