Declan has 9 dimes and 8 quarters in his pocket.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of dimes and y represent the number of quarters.
A dime is worth 10 cents. A quarter is worth 25 cents.
Hence:
x + y = 17 (1)
Also:
10x + 25y = 290 (2)
From equation 1 and 2:
x = 9, y = 8

Answer:
The angle is 120 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
So if our angle is x it's supplement is 180 - x.
So we have the equation:
x = 2(180 - x)
x = 360 - 2x
3x = 360
x = 120 (answer).
Answer:
maybe 6 1/2
Step-by-step explanation:
If the height of the building is 100 ft, and the angle made with the ground is 30°:
You can say that tan(30) = 100/x
Rearranging for x you get x = 173.2 ft
