Answer:
The tree is 14 ft. tall.
Step-by-step explanation:
Height of the building/ Height of the tree = Shadow of building/ Shadow of tree
30/x = 75/35 Cross multiply
75x = (30)(35)
75x = 1050
x = 1050/75
x = 14
Answer = 2

Answer:
4
Step-by-step explanation:
Two ways to solve this - either divide 140 by 35 (140/35 = 4)
or keep adding 35 until you reach 140: 35+35+35+35 = 140
Answer:
13.86
Step-by-step explanation: First- (2.3 * 4/10)
which gives you 27/10
Then (4.16 * 7/1)
Which gives you 11.16/1 (basically 11.16)
Then divide 27/10 which gives you 2.7
add 11.16+2.7
which adds up to 13.86
In this question, they gave you the system of equations. You just need to use the two of them.
We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.


If we know the m form of f, we can convert the second equation and find the answer:

Plug in the m value of f:

Distribute the 5:

Subtract -75 from both sides:

Combine like terms:

Divide both sides by -2:

So, we learned that the number of the multiple-choice questions is 12.
