Charlie takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $98 per credit hour, and at Pinewood, class fees are $115 per credit hour. Charlie is taking a combined total of 13 credit hours at the two schools. Suppose that he is taking w credit hours at Westside. Write an expression for the combined total dollar amount he paid for his class fees. total paid (in dollars) =
@sangya21 @kah.x ????? do you know
98w+115p=total amount paid.
it doesnt give you enough info to actually solve it
@kah.x is right
its says it wrng
@sangya21 @kah.x was the 13 supposed to be used
w+p =13
yeah, but you cant really put that into the current equation because theres not enough information to solve it
they wont let me put a equal sign
it was 98w+115(13-w) @sangya21
thats also a way to put. Sorry for the wrong
Yesterday, Rachel went on a bike ride. Her average speed was 10 miles per hour. Today, she went on another ride, this time averaging 14 miles per hour. In the two days, she biked for a combined total time of 10 hours. Let x be the number of hours she biked yesterday. Write an expression for the combined total number of miles she biked in the two days.
its okay can u help with that one @sangya21 @kah.x
you're so helpful
we are given speed and time for yesterday speed = 10mph time = x hours distance = speed * time d1= 10x d2 = distance on day 2 d2 = 14(10-x) 10x+14(10-x)
@uri @Becki @ChasingMaggie @sangya21 The sum of the four angle measures of any convex quadrilateral is 360 degrees. Suppose that a convex quadrilateral has angle measures of 60 , +8y3 , and −6y7 degrees. Write an expression for the degree measure of the fourth angle.
