First expand the brackets by multiplying each thing inside the brackets by 2:
4x−10=6x+4. then minus the 4x so there are only x 's on one side:
−10=2x+4. then minus the 4 so there are only numbers on one side and x 's on the other:
−14=2x. then divide by 2 to get the value of x
Answer:
$1
Step-by-step explanation:
5 cans of corn -- 5 * $1 = $5
4 cases of water -- 4 * $4 = $16

Answer:Maria rate = 1/13 job/hr
-----
Felipe rate = 1/16 job/hr
----
Together rate = 1/x job/h
Step-by-step explanation: rate + rate = Together rate
1/13 + 1/16 = 1/x
----
16x + 13x = 13*16
------
29x = 13*16
x = 7.17 hrs = 7 hr 10 min 12 seconds (time to do the job together)
