Answer:
Slope: y = x
Step-by-step explanation:
Two ordered (-5,0) and (0, 5)
slope = Change in the y-values/ change in the x-value
slope = (5 - 0)/ [0 - (-5)] = 5/5 = 1
slope-intercept form: y = mx + b Using ordered pair (0, 5)
y = mx + b
5 = 1(0) + b
5 = 0 + b
5 = b
Slope-intercept form: y = mx ; y = x
65 + 10x < 120
x = 5 hours and he would have 5 dollars left
Answer: 210
Step-by-step explanation:
42% is equal to the fraction 42/100.
We can multiply 42/100 by 500 to find how much candy was eaten.
42/100 x 500 = 210.
Therefore, 210 pieces of candy were eaten. Hope this helps and good luck!
Answer: 7 gallons; 14 gallons
Step-by-step explanation:
Let the amount of water in the first container be x.
Since one container holds 2 times as much as the other, the second container will be: = x × 2 = 2x
The total amount of water is 21 gallons. This means:
x + 2x = 21
3x = 21
x = 7 gallons
First container = 7 gallons
Second container= 2x = 2×7 = 14 gallons
