Answer:
No
Step-by-step explanation:
Basically, the statement is saying: 35 ft per 7 seconds. In math, the word <em>per</em> means there is a fraction involved, so <em>per</em> can be rewritten with a "/". So our fraction would be 35/7. This can be simplified to 5/1, which means 5 ft per second.
It would not be 7 feet for every second, it would be 5 feet for every second.
4x-2y=10
7x+2y=23
First, we can solve one of the problems in order to come up with an expression to represent y.
-2y=4x+10
y=-2x-5
Now that we have our y value, we can plug it in to the other equation.
7x+2(2x-5)=23
7x+4x-10=23
11x=33
x=3
There's your x value, 3. I am going to solve for y as well just so that you can see how to check your work.
We can plug our x value into the other equation now to find y.
4(3)-2y=10
12-2y=10
-2y=-2
y=1
Would you look at that? We have both the x and y values. Now we can just plug them in to either equation.
7(3)+2(1)=23
21+2=23
23=23
23 indeed equals 23, therefore proving that both variables are correct. There you go!
1344 would be the answer by multiplying .03 times 1200 and getting 36 then multiplying it by 4 and then adding it to 1200 getting 1344.

I would assume the answer would be a. 18 assuming your trying to find the entire value of a triangle but have a missing value
