Answer:
the tip was $7.77
Step-by-step explanation:
49.77-42 we do this since the bill originally was only $42 we end up with 7.77
Two equations are given below:
a − 3b = 4
a = b − 2
What is the solution to the set of equations in the form (a, b)?
(−2, −2)
(−3, −1)
(−9, −7)
(−5, −3)
HELP! BRAINLEST IF STEP BY STEP SO I CAN UNDERSTAND
Answer:
Step-by-step explanation:
lets start here:
we can do 7x4=28
but we can't do 7x5, because 7x5 is 35, which is bigger than 34
so, you do 34 - 28 which gives you 6, and 6 is smaller than 7 so we can't subtract 6- a bigger number! so its 4 R 6!
hope this helped!
