Answer:
100$
Step-by-step explanation:
he profit from 1 popcorn=0.85$
from 200=170$
170$-70$=100
Answer:
Tara's current expression finds how much the school will be keeping. 50 x 2/5 (also written as 50 x 0.4) totals out as 20. $20 is 2/5 of $50. The expression that Tara SHOULD have written to find how much goes to the candle company would be 50 x 3/5 (also written as 50 x 0.6), as this adds up to 30. $30 is 3/5 of $50.
Step-by-step explanation:
50/5 = 10 which means that 1/5 of 50 = 10.
2/5 of 50 ($20) is kept by the school. This is what Tara's expression finds. This means that $30 is sent to the candle company, and can be found with the expression 50 x 3/5.
The decimals are created by dividing the numerator of the fraction by the denominator (I find it easier to do math with decimals).
Answer:8
Step-by-step explanation: 7x8=56
To understand problems like these, we must understand how Slope Intercept Form (SIF) works, and how to solve an equation.
<span>A
</span>SIF is "y=mx+b" where "m" is the slope and "b" is the y-intercept.
y='m'x+''b''
y='3'x-''4''
We can see that in this equation, the slope is 3/1 or 3, and the y-intercept is -4.
<u>B
</u>For this one, we must solve for "y," and then proceed with the same thing we did in Part A.
4x-5y=15
-4x -4x
-5y=-4x+15
/-5 /-5
y='4/5'x-"3"
Using the math above, we can see that the slope is 4/5, and the y-intercept is -3.
Answer:
slope = 
Step-by-step explanation:
Slope-intercept form is the way in which an equation is written to easily identify the line's slope and y-intercept. It is represented by the equation y = mx + b, in which m represents the slope.
By looking at the equation, we can see that it takes the y = mx + b format - y is isolated - therefore it is in slope-intercept form. Remember that the number in place of the m would represent the slope - and in this case, that number is .
