Question

The sum of the four angle measures of any convex quadrilateral is
360 degrees. Suppose that a convex quadrilateral has angle measures of
60, 8y+3, and 6y-7 degrees. Write an expression for the degree measure of the fourth angle.
@uri @Becki @ChasingMaggie @kah.x @sangya21

Answer 1

60+8y+3+6y-7+x=360 where x=the 4th angle of the quadrilateral

Answer 2

So, the fourth angle would be 360 minus the other three angles, do you agree?

Answer 3

okay so the degree measure of the 4th angle is just 360 as the answer

Answer 4

No. 360 is the number of degrees in all four angles total. They gave you 3 of them and told you the total (360).

Answer 5

okay so how do i find the answrr

Answer 6

x=360 -(all the other angles)

Answer 7

See my first response. I did everything but write it in equation form for you.

Answer 8

all the other angles are 60, 8y+3 and 6y-7?

Answer 9

im confused what im subtravting?

Answer 10

@sangya21 what are the other angles?

Answer 11

x = 360-(60+8y+3+6y-7)

Answer 12

oh okay thank you.

Answer 13

can you also help with this one

Latoya has a job transporting soft drinks by truck. Her truck is filled with cans that weigh
14
ounces each and bottles that weigh
70
ounces each. There is a combined total of
770
cans and bottles in her truck.
Let
x
be the number of
14
-ounce cans in her truck. Write an expression for the combined total weight (in ounces) of the cans and bottles in her truck.

Answer 14

@sangya21 @kah.x

Answer 15

14x +70(770-x)

Answer 16

Two trains leave stations
588
miles apart at the same time and travel toward each other. One train travels at
115
miles per hour while the other travels at
95
miles per hour. How long will it take for the two trains to meet?
