Answer:
it will take 100,000 more days.
you can do this by dividing 10 and 1,000,000
Answer:
D. (12 + 0.08)
(Can't explain in enough time but they both equal the total cost of $12.06)
The answer is 8 because 8 x 8 = 64 If you see these kinds of problem what is the square root of 25, 64, 36... means 5 x 5 = 25, 8 x 8 = 64, 6 x 6 = 36 If you see square root of 48. It would come out to be a decimal number.
Answer:
2
Step-by-step explanation:
We can set up equation for this one.
Let's say the number is X.
the sum of X and 14 can be expressed as : X+14
five times the sum of X and 14 can be expressed as 5(x+14)
and 5(X+14) = 80
The number is 2
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
