7x - 35 < 2(x -5)
Use distributive property on the right side:
7x -35 < 2x - 10
Add 35 to both sides:
7x < 2x + 25
Subtract 2x from both sides
5x < 25
Divide both sides by 5
X < 5
Answer:
Approximately 149 cubic centimeters of water
Step-by-step explanation:
step 1
Find the volume of water in the tank
The volume of a rectangular prism is equal to

we have

substitute

step 2
Find the volume of the cylindrical container
The volume of the cylinder is equal to

we have
---> the radius is half the diameter


substitute


step 3
To find out how much water is still in the tank, subtract the volume of 10 containers of water from the volume of the tank
so

therefore
Approximately 149 cubic centimeters of water
To simplify this all you need to do is distribute the 4x across each term in the parenthesis
X - 15 + 30 - 12 = 18;
Then x - 15 + 18 = 18;
x + 3 = 18;
x = $15 ( money has Ming-Li to begin with ).
Set the number of chickens as x and number of cows as <span>y
</span>so the farmer has total 28 animals
so x+y=28
you know that since the animals are healthy
chickens will have 2 legs and
cows will have 4 legs
the total number of legs are 64
so 2x+4y=64
since you want to find the number of cows
so from the first equation <span>x+y=28
</span>we will get another equation <span>x=28-y
</span>then plug into <span>2x+4y=64
2(28-y)+4y=64
56-2y+4y=64
56+2y=64
-56 -56
2y=8
y=4
</span>
