Using the first equation:
4x = y + 3 ---> y = 4x - 3
We then substitute this into the second equation:
7x - 9(4x-3) = -2 ---> 7x - 9x + 27 = -2 ---> -2x = -29 ---> x = 14.5
Answer:
7 + 11 + 11
Step-by-step explanation:
7 + 11 = 18
18 + 7 = 25
5/20 in simplest form
1) 5/20 can be divided by 5
5 ÷ 5 = 1
20 ÷ 5 = 4
It cant be divided any more
5/20 in simplest form is 1/4
Answer: 7 laps
Step-by-step explanation:
The athlete planned to run 3 miles
1 lap = 3/7 miles
x laps = 3 miles
by proportion :
x × 3/7miles = 3 miles
x = 3 ÷ 3/7
x = 3 x 7/3
x = 7
Therefore: the athlete will run 7 laps
(-4,6)
The x value changes bc since it is a reflection y cannot change and x becomes negative
