Answer:
a 25 questions, 4 points b 19 questions
Step-by-step explanation:
a 96:100 = 24 : x
x = (100 x 24)/96 = 25 questions
100 : 25 = 4 points
b 76:100 = x : 25
x = (76 x 25)/100 = 19 questions
Answer:
24 hours
Step-by-step explanation:
Hi,
The equation to represent this situation would be 45x + 720 = 1800
(45 is the cost per hour, x is the number of hours since you don't know how many hours that person was there for. 720 is there because no matter what, you have to pay 720 to visit and = 1800 is the total cost)
Now, solve for x.
45x + 720 = 1800
Subtract 720 on both sides...
45x = 1080
Divide by 45 on both sides...
x = 24
He worked 24 hours that week.
Hope this helps :)
Answer:
Washer is $676
Dryer is $338
Step-by-step explanation:
1014 divide by 3 gives you 338.
338 x 2 = $676
676 is twice 338.
676 + 338 = 1014
Y = -3. Yeah this can be hard at first but you'll get the hang of it, its simple once u have that clicking moment.
What the goal is is to get y by itself, right? Then u would have y = blank and thats what u need because ur trying to find y. So to get y alone and have that y = blank, u can "balance the equation." That means if u add something on the left side of the equation (before the equal sign) u have to add it to the right. Same with subtraction. In this equation, u would subtract 6 from both sides so there would be no 6 left on the left and a 6 on the right instead. ask me questions if u need more help! :)
