Answer:
320 pound
Step-by-step explanation:
Ratio is decently easy after u understand the concept
So... This is what the question gave
Jupitar : earth
8 : 3
In other words, if u weigh 8 pound on Jupitar, u would weigh 3 pounds on earth
Therefore now they say on earth, the person weighs 120 pound, so let's just put in this value
Jupitar : earth
8 : 3
? : 120
Now its called ratio bcuz the increase at the same pace
So now look at the earth part, u got to find out how did 3 become 120, so just divide them
120/3 = 40 , so 3 x 40 = 120
So if they multiplied the right ( earth) by 40, u do the exact same on the left ( Jupitar)
8 x 40 = 320
Thats your answer my friend
Answer:
a = 20 . . . . liters
Step-by-step explanation:
To solve this, multiply the equation by 30+a:
a = 0.4(30 +a)
a = 12 + 0.4a . . . . . eliminate parentheses
0.6a = 12 . . . . . . . . subtract 0.4a
a = 12/0.6 = 20 . . . divide by the coefficient of a
20 L of alfalfa must be added
_____
<em>Check</em>
20/(30+20) = 20/50 = 40/100 = 0.4 . . . . . . answer checks OK
Answer:
<h3>30 tiles need to buy for same cost in both store.</h3>
Step-by-step explanation:
Let x be the number of tiles to buy for same cost in both store.
18+0.69 · n = 1.29 · n,
1.29n -0.69n =18 or
0.6n =18
n =18/0.6=30
Therefore, 30 tiles need to buy for same cost in both store.[Ans]
