Answer:
15
Step-by-step explanation:
if 3x3 is 9 and 4x3 is 12 then 5x3 is 15
3y = 5x+30 , y+5x = 50
using elimination method ...
3y-5x=30
+ y+5x=50
——————
4y = 80
y= 20
so using one of the original equations..
20 + 5x = 50
5x = 30
x =6
x = 6
y = 20
Answer:
Distance = 110.5 cm
Step-by-step explanation:
It is given that,
The basement floor is at an elevation of −10.5 feet
The second story floor has an elevation of 121 feet.
We need to find the distance between the basement floor and the second story floor.
Distance = -10.5 + 121
= 110.5 feet
So, the distance between the basement floor and the second story floor is 110.5 cm.
Answer:
1110 liters
Step-by-step explanation:
Let x = amount of 26% juice.
Amount of tomato juice:
740 liters of 36% juice contains 0.36(740) = 266.4 liters of tomato juice
x liters of 26% juice contains 0.26x liters of tomato juice
The result will be x + 740 liters of the juice blend at a concentration of 30%. It contains 0.3(x + 740) liters of tomato juice.
266.4 + 0.26x = 0.3(x + 740)
266.4 + 0.26x = 0.3x + 222
-0.04x = -44.4
x = 1110
Answer: 1110 liters
