Let x be price of apples per pound and y be price of potatoes per pound.
We can set a system of equations by our given information as:
Now we will use substitution method to solve our system of equations.
From equation 2 we will get,
Upon substituting value of x in equation 1 we will get,
Therefore, price of potatoes will be $0.99 per pound.
Now let us find price of apples by substituting y=0.99 in equation 2.
Therefore, price of apples will be $1.49 per pound.
This question, at first, may seem quite confusing. However, this problem can be simplified by just analyzing the triangle with "y" in it.
It is given that one angle of the triangle is 48 degrees. The other interior angle must be 90 degrees since the angle adjacent to that is a right angle, and supplementary angles add up to 180 degrees.
Thus, we have a triangle with angles of 90 degrees, 48 degrees, and y degrees. These must all add up to 180 because this is a triangle.
Subtract both sides by 90 and 48
Hope this helps and have an awesome day! :)
Answer & Step-by-step explanation:
6/8 as a decimal is 0.75.
3/4 as a decimal is also 0.75.
Therefore, they hiked the same distance.
How to round a whole number to the nearest tenth.
When rounding whole numbers to the nearest tenth, you need to look at the ones place, if the number is smaller than 5, then round down. If the number in the ones place is greater than 5, then round up.
Example:- If they told me to round 67 to the nearest tenth, I need to find the ones place.
The ones place in 67 is the 7.
7 is greater than 5, therefore, we need to round up.
We round 67 to 70.
So our answer is 70.
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
