Answer:
The volume of the glass is 217.8 cm³
Step-by-step explanation:
If the glass were initially 4/7 full, that means 3/7 of the volume is still available to hold more juice.
Let v represent the volume of the glass.
Then (3/7)v + 70 cm³ = (3/4)v.
We need to solve this for v.
Here the LCD is 28. Thus,
(3/7)v + 70 cm³ = (3/4)v → (12/28)v + 70 cm³ = (21/28)v.
Subtracting (12/28)v from both sides, we get:
70 cm³ = (9/28)v.
We can isolate v by mult. both sides by the inverse of 9/28, which is 28/9:
(28/9)(70 cm³) = v
The volume of the glass is 217.8 cm³
Answer:
0.8 of a cake
Step-by-step explanation:
all you do is divide 4 by 5
It would be (all under a big square root) (-7-5)squared + (3+2) squared. This equals to about root 169
Answer:
{x | x ∈ R, x > 3}
Step-by-step explanation:
We are given the following inequality:
x - 5 > -2
In order to find the solution, we have to isolate the x on one side. This can be done by adding 5 to both sides of the inequality as shown below:
x - 5 + 5 > -2 + 5
x > 3
So the solution of the inequality is set of all numbers where x > 3. This is represented by 3rd option.
So, {x | x ∈ R, x > 3} is the answer.
