Answer:
x = 2
Step-by-step explanation:
5x + 2 = 12
Subtract 2 from both sides
5x + 2 - 2 = 12 - 2
Simplifying
5x = 10
Divide both sides by 5
5x / 5 = 10/5
Simplifying
x = 2
Answer:
1.922 miles is equivalent to 3.1 kilometers.
Step-by-step explanation:
Given:
1 km = 0.62 miles.
3.1 km = ? miles
Now, in order to find the number of miles equivalent to 3.1 km, we use unitary method with the help of the conversion factor.
From the conversion factor, we can conclude that kilometer is a smaller unit compared to that of mile.
So, conversion factor = 
The formula to transform 'n' kilometers to miles is given as:
Therefore, 3.1 km = 
3.1 km =
miles
Therefore, 1.922 miles is equivalent to 3.1 kilometers.
Answer:
$5,500
Step-by-step explanation:
Let A be the amount invested at 3%, B the amount at 4%.
Total value:
1.A%2BB=8000
Interest:
Multiply eq. 1 by -3 and add to eq. 2,
-3A-3B%2B3A%2B4B=-24000%2B29500
highlight%28B=5500%29
Then from eq. 1,
A%2B5500=8000
highlight%28A=2500%29
OH MY GOSH I THINK I GET IT! difference as in division. it wants you to i think make for example make 2 the answer to an equation like 5-3=2! 5 and 3 are prime numbers.
