Answer:
The answer in image one is f(x)=2x Left
The answer in image two is f(x)=x Center
the answer in image three where right Right
Let x be the number of nickels and y be the number of quarters.
Then, x + y = 42 --- (1)
It is given that total value = 4.90.
Therefore, 0.05x + 0.25y = 4.9 --- (2)
Multiply (1) by 0.25
0.25x + 0.25y = 10.5 --- (3)
Now, subtract (2) from (3), we get,
0.2x = 5.6
Divide both sides by 0.2.
x = 28
x + y = 42
y = 42 - x
= 42 - 28
= 14
Hence, Mary has 28 nickels and 14 quarters in total.
tan theta = perpendicular / base
tan B = 40/9
so option D is answer
Answer:
36x + 8
Step-by-step explanation:
This is incomplete, but if you meant simplify then here you go:
8 + 6x * 4+2
8 + 6x * 6
8 + 36x
36x + 8
<span>If 43% of adults say cashews are their favorite kind of nut, then if you ask 12 adults the result should be: 12 adults x 43%= 5.16 adults.
If you round the result, you will get 5 of 12 adults saying that cashews are their favorite nut. Then the right option would be </span><span>(b) at least four</span>
