Answer:
x = -7, y = -9
Step-by-step explanation:
The coefficient (the number before) the y is the same but the signs are opposite so add the equations together:
x-3x+y-y=-16+30
-2x=14
x=-7
y=-16-x=-16--7=-9
In a triangle, the three interior angles always add to 180°
x + 3x + 5x = 180
9x = 180
x = 180/9
x = 20
<span>the smallest angle = x = 20</span>°
Answer:
100
Step-by-step explanation:
You are given the equation
There are 5 coefficients:
Two of them are integers
two of them are decimals with one digit after point
and one is a decimal with two digits after point
To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:
Answer:
A. 90 degrees
Step-by-step explanation:
Draw it out, it will always be 90 because of the pentagon shape.
Answer:
57/80L
Step-by-step explanation:
Given that the capacity (i.e maximum possible volume) of a pitcher is 9/10L
1st Pitcher is 3/8 full of milk
Hence Vol of milk in 1st pitcher = 9/10 x 3/8 = 27/80L
2nd Pitcher is 5/12 full of milk
Hence Vol of milk in 2nd pitcher = 9/10 x 5/12 = 3/8 = 30/80L
Total volume = 27/80 + 30/80 = 57/80L
