Answer:
x = -2.3
Step-by-step explanation:
4x + 1.3 = -7.9
First we want to combine the like terms.
Subtract 1.3 from both sides.
4x = -9.2
Now we want to isolate x by dividing both sides by 4.
x = -2.3
Check your answer by plugging x back into the original equation.
4x + 1.3 = -7.9
4(-2.3) + 1.3 = -7.9
Multiply.
-9.2 + 1.3 = -7.9
Add.
-7.9 = -7/9
Your answer is correct.
Hope this helps!
Any number that can be rewritten as a simple fraction is a rational number. This means that natural numbers, whole numbers and integers, like 5, are all part of the set of rational numbers as well because they can be written as fractions, as are mixed numbers like 1 ½.
Answer:
Step-by-step explanation:
1. 12
2. 12/3.5 = 3.43
3. 12/15 = 0.8
4. 3.43/0.8
5. 315/x
6. 315/x = 0.8/3.43
7. (315)(3.43) = 0.8x divide both sides by 0.8, so x = 1,350.5625 feet.
