Step-by-step explanation:
Step:1
From given, the rate is
= 15 miles per gallon
= \frac{15}{1}115 = 15 miles.........................(1)
Step:2
Check for Option A,
= 30 miles per 3 gallons
= \frac{30}{3}330 = 10 miles.....................(2)
From the eqn (1) and (2),
Eqn (1) ≠ Eqn (2)
Step:3
Check for Option B and C are not match with given because, Miles provided first or top then the gallons provided the last or bottom.
Step:4
Check for Option D,
= 60 miles per 4 gallons
= \frac{60}{4}460 = 15 miles.........................(3)
From the eqn (1) and (3),
Eqn (1) ≠ Eqn (3)
Result:
The equivalent unit rate for 15 miles per gallon is 60 miles per 4 gallons (\frac{60 miles}{4 gallons}4gallons60miles ) .
Answer:
Step-by-step explanation:just do 4x+3
Answer: False
The tenth place means there will be 1 decimal.
75.2515
because they 5 is left to the 2, and 5 means we round up, the 2 becomes a 3. Therefore, it would equal 75.3
<u>The present age of the man is 36 years and his son is 11 years.</u>
Answer:
Solution given:
let the age of man be x.
and his son be y.
By question
x-6=6(y-6)
x=6y-36+6
x=6y-30. ......(1)
and
3(x+4)=8(y+4)
3x+12=8y+32
3x=8y+32-12
3x=8y+20. ...(2)
substituting value of x in equation 2 ,we get
3(6y-30)=8y+20
18y-90=8y+20
18y-8y=90+20
10y=110
y=110/10
y=11 years
again substituting value of y in equation 1 we get
x=6*11-30
x=66-30
x=36 years
I believe the slope of the line is 1/3
