We need to add like terms and distribute before we try to isolate X.
10x+3=8x+4-2
10x+3=8x+2
Now let's isolate x. We should start with subtracting 8x from both sides.
2x+3=2
Now, let's subtract 3 from both sides.
2x=-1
Now divide each side by 2.
X=-0.5
We now know x is -0.5, so let's check.
5(-0.5)+5(-0.5)+3=4[2(-0.5)+1]-2
-2.5-2.5+3=4(0)-2
-5+3=0-2
-2=-2
So, X= -0.5
Answer:
You would earn $81.25 per week.
Step by step process:
1 hour = $6.50 ( per hour means what you would get in an hour's time.)
12 1/2 = x
If more less divides. Let x be the subject. ( 12 1/2 is the same as 12.5 or 25/2)
x = 12.5 hours × $6.50 / 1 hour ( 1 hour will cancel out 12.5 hours 12.5 times.)
x= 12.5 × $6.50
x = $81.25

D - the shortest distance from the ship to the shore.
d / ( 17 - x ) = tan 32° = 0.62487
d / x = tan 53° = 1.32704
d = 0.62487 ( 17 - x )
d = 1.32704 x
0.62487 ( 17 - x ) = 1.32704 x
10.62279 - 0.62487 x = 1.32704 x
x = 10.62279 : 1.95191
x = 5.44226 miles
d = 5.44226 · 1.32704
Answer:
d = 7.222 miles
Step-by-step explanation:
this simply means that the sum of both short segments must be the same as the length of the whole line.
so,
x + 6 + x + 8 = 10
2x + 14 = 10
x + 7 = 5
x = 5 - 7 = -2
