Speed of boat r mi/hr
speed of currect c mi/hr
speed downstream (c+r) mi/hr
but
distance= 4miles
time=1.5 hours
thus
speed=distance/time
hence:
4/1.5=(c+r)
thus
4=1.5c+1.5r
hence the answer is:
4=1.5c+1.5r
Answer:
-2\9
OR
-0.2
Step-by-step explanation:
−2(4+3x)=3(x−2)
Use the distributive property to multiply −2 by 4+3x.
-
−8−6x=3(x−2)
Use the distributive property to multiply 3 by x−2.
-
−8−6x=3x−6
Subtract 3x from both sides.
−8−6x−3x=−6
-
Combine −6x and −3x to get −9x.
−8−9x=−6
Add 8 to both sides.
−9x=−6+8
-
Add −6 and 8 to get 2.
−9x=2
Divide both sides by −9.
x = 2\-9
Fraction 2\-9 can be rewritten as -2\9 by extracting the negative sign.
SO..
ANSWER IS = -2\9
Answer:
Step-by-step explanation:
∠2=∠3 (alternate interior angles)
3x-10=x+30
3x-x=30+10
2x=40
x=20
4^5
4 is the base
5 is the power
Same as writing it like
4 x 4 x 4 x 4 x 4
