Answer:
x = 27
Step-by-step explanation:
I'm assuming the equation looks like this:

Here's how to solve for x:

(subtract 5 from both sides)

(Find the GCF of 3 and 9, which is 3. Multiply 2/3 by 3/3. You get 6/9)

(add like terms)

(multiply 9/5 to both sides, which is the same as dividing both sides by 5/9)
x = 27

Answer:
5 tons
Step-by-step explanation:
Answer:
50 of D and 10 of C
Step-by-step explanation:
First of all, put this data into 2 equations.
You sold 60 items, so C+D=60
C is $5 so we can represent it by 5C
D is $7 so we can represent it by 7D
You made $400 total from C and D, so 5C+7D=400
We can use simultaneous equations to solve this.
To eliminate one of these variables, we'll multiply the first one by 5 to make it 5C like the other.
5(C+D=60) (make sure you multiply both sides.)
so 5C+5D=300
5C+7D=400
Now we solve it:
5C-5C+7D-5D=400-300
7D-5D=100
2D=100
D=50
Now we can substitute this with one of the equations to find C
C+50=60
C=60-50
C=10
so, (10x5)+(50x7)=400

Step-by-step explanation:
Juan forgot to simplify 20/21 when he got his answer and was supposed to round to the nearest 6 decimals places and when he simplify it, it was supposed to be written in decimal form
