Answer: 3/2
Step-by-step explanation:
The first one: y=2x+5
X=2y+5.Then solve for y after switching x and y
X-5=2y, X-5/2=y
Since F-1= X-5/ 2, we plug the value of X in
8-5/2, so it should be 3/2
Answer:
= -2x
Step-by-step explanation:
3x and -5x are like terms and -10 and 10 are also like terms. like terms can be added together
= -2x cause the 10's cancel out
Answer:
B
I
Step-by-step explanation:
A triangle's angles must add up to 180
68+90+x=180
158+x=180
22=x
3 and 2 must add up to 180
70+x=180
angle 2= 110
angle 2 and angle 1 have to add up to 180 as well
110+x=180
andgle 1= 70
60 mins in an hour
18/60 is the fraction
3/10 is the simplest form (dividing by 6)
