Answer:
x+y
Step-by-step explanation:
Let's pretend the value of the crayon's is 'y'. The value of the markers is 'x'. If we add them together, we get x+y. This is because we do not know the value of each variable.
Hope this helps! Have a nice day <3
The answer would be D. 32
Why? The triangle in the problem is an isosceles triangle. That means the two legs of the triangle are equal and the angle opposite to the equal legs are also equal.
Therefore, angle C is also 74°.
The sum of the interior angles of a triangle is equal to 180°.
Thus,
180° = ∡A + ∡B + ∡C
180° = 74° + ∡B + 74°
180° = 148° + ∡B
∡B = 180° - 148°
∡B = 32°
Answer:
--- Movies
--- Video games
Step-by-step explanation:
Represent the movies with M and the video games with V.
The first month, the expression is:
The next month, the expression is:
Required
Find M and V
We have:
--- (1)
--- (2)
Multiply (1) by 3.
3 *
--- (3)
Subtract (1) from (3)
-
-------------------------
Divide by 4
Substitute 5.5 for V in (1)
Subtract 16.5 from both sides
Divide by 2
Okay so at the bottom it says square both sides so you have to square (x+1). when you do that you're basically just doing (x+1)(x+1) and you just use the foil method and end up with x^2 + 2x + 1
So assuming that the only had 3+6=9 tiles
what we have to do it find teh area total
area=legnth times width
3 tiles are 3 and 1/2 times 3
3 times 3 and 1/2=10 and 1/2
times 3 tiles
10 and 1/2 times 3=31 and 1/2 squar inches
6 tiles are 4 by 3 and 1/4
4 times 3 and 1/4=13
6 tiles times 13 inchessquare=78
so we add
31 and 1/2+78=109 and 1/2 square inches
