Answer:
Step-by-step explanation:
since they are both equal to 'y', you can eliminate the y but letting the value of y equal to each other
if they are not both equal to 'y', then solve the equation by putting y itself on 1 side
1. sub y=-2x into 2nd equation
-2x = 3x + 25
then solve for x
-5x = 25
x= -5
2.
y-2 =12x
y = 12x +2
(sub this equation into y=x+2)
12x + 2 = x + 2
11x = 4
x = 4/11
hope this makes sense, please let me know if it doesn't and i'll help out some more
i'm not that great at explaining, sorry
Answer:
multiply by 5
Step-by-step explanation:
in order to get t by itself, you must do the incerverse operation of division, which is multiplication
5(t/5)=5(2.9)
the 5 crosses out and you get
t=14.5
10 - 5 = 5. July has 5 bars remaining
Have you learnt about prime numbers yet? 5 is a prime number so you can't break it up into smaller numbers other than obviously 5*1. 39 is not a prime number. At first glance you should be able to tell that its a multiple of 3 right?
39=3*13
Now you have smaller numbers.
3*13*5=13*15.
I guess that's what the answer is.
