Step-by-step explanation:
10x + 25 = 50
10x=25
x=2.5
Answer:
A. Sin 2x
Step-by-step explanation:
This is a trig function and has the shape of sine or cosine. Since it intersects at (0,0), it is likely a sine graph. A normal sine graph starts at (0,0), crests up at 1, and crosses back down at the x-axis at (3.14, 0). However, this graph starts at (0,0) and crosses back again at half that value. This graph has been horizontally compressed by multiplication of a number greater than 1. So this graph is Sin 2x.
We know, the sum of all the angle in an triangle is 180,
So, We can calculate adjacent angle of angle 1,
Let, that adjacent angle = b
So, 34 + 103 + b = 180
b = 180 - 137
b = 43
Now, angle b forms linear pair with angle a, so their sum would be 180
a + b = 180
a + 43 = 180
a = 180 - 43
a = 137
In short, Your Answer would be Option C

Answer: DeMarco still needs 2 1/2 cups of tomato sauce.
Step-by-step explanation:
Solve for 3 3/4 cups (needed) - 1 1/4 cups (have).
2 2/4 cups
Simplify:
2 2/4 -> 2 1/2 cups
