2.5x + 0.1x = 2.6x
2.6x - 0.01x = 2.59x
Answer:
Board 1 = 1.2m
Board 2 = 2.4m
Board 3 = 3.6m
Step-by-step explanation:
Board 1 = x
Board 2 = 2x
Board 3 = 3x
x + 2x + 3x = 6x
7.2 /6 = 1.2
Board 1 = 1.2
Board 2 = 2 (1.2) = 2.4
Board 3 = 3 (1.2) = 3.6
Answer:
They are proportional
Step-by-step explanation:
Y/X represents coordinates Y being rise X being run. So Y/X is equal to rise/run. If there was a coordinate grid, if the two points created a straight line that slant to the right I would be proportional. Since all I see is rise/run= 5 they are proportional. 5 represents the slope.
ANSWER:
24 points.
The amount of points Leila needs to score in her next game so that her average is 27 points per game is: 24 points.
STEP-BY-STEP EXPLANATION:
Let the amount of points Leila needs to score in her next game so that her average is 27 points per game = x
27 = total no. of points / total no. of games
27 = ( 33 + 28 + 24 + x ) / ( 3 + 1 )
27 = ( 85 + x ) / 4
27 × 4 = 85 + x
85 + x = 108
x = 108 - 85
x = 24
Your equations would be:
X * y = -5
X + y = 2
Your answer would be -1.5 and 3.5
