Hi there! A = 78
A + 44 = B
We can plug in the values of A and B into the equation. We then get an equation with only one variable (x), which we can solve.
1x + 76 + 44 = - 6x + 134
Collect terms.
1x + 120 = - 6x + 134
Add 6x to both sides.
7x + 120 = 134
Subtract 120 from both sides
7x = 14
Divide both sides by 7
x = 14 / 7 = 2
A = 1x + 76
Now plug in the value of x we just found
A = 2 + 76 = 78
Answer:
40,885,048
Step-by-step explanation:
first find 3^12 and then find 7^9.
3^12 = 531,441
7^9 = 40,353,607
Add these together and you'll get 40,885,048.
Welcome! Hope this helps.
Answer:
4
Step-by-step explanation:
break the first 2 into its components, 1 and 1 because 1 + 1 = 2.
Break the second 2 into its components, 1 and 1 because 1 + 1 = 2.
Combine all the components. Since they're all ones, you just have to count your fingers 4 times!
1 + 1 = 2. 2 + 1 = 3. 3 + 1 = 4!
1 + 1 + 1 + 1 = 4!
4 is the correct answer.
Answer:
Percentage of interest at which the money is invested = 5%
Time for which the money is invested = 3 years
The final amount after 3 years = $820
Let us assume the principal amount = x dollars
We can conclude that the principal amount invested was $708.35.
