3
Step-by-step explanation:
29 = 10x - 1
+4
30 = 10x
30 divided by 10 = 3
3 = x
So Addy is 3.
Answer: y = 2
Step-by-step explanation:
we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:
since x=2y+1,
we can say that:
(2y+1)+2y=9
then we solve this equation,
first we expand the brackets- 2y+1+2y=9,
then we combine like terms- 4y+1=9
then we take 1 away from both sides- 4y=8
then we divided both sides by 4
y=2
Hope this helps xx
100÷11=9.09090909
converting it it will be 9.1 miles per hour
12 it's adds ×÷2 ( 8÷2=4) and then add the two numbers (8&4)
Answer:
Not a function
Step-by-step explanation:
