Answer:
x = 12
Step-by-step explanation:
given 2x - 7 = 5 + x ( subtract x from both sides of the equation )
x - 7 = 5 ( add 7 to both sides )
x = 12
Answer:
interval
Step-by-step explanation:
In summary, nominal variables are used to “name,” or label a series of values. Ordinal scales provide good information about the order of choices, such as in a customer satisfaction survey. Interval scales give us the order of values + the ability to quantify the difference between each one.
"Percent" means " /100 ".
Whatever the number of percent is, write it down as the numerator
of a fraction, and write down 100 for the denominator.
Then look at the fraction, and simplify it if possible, using the
usual techniques for simplifying fractions.
Answer with Step-by-step explanation:
A candle is 4 inches tall and burns at the rate of 0.6 inch per hour.
i.e. after 1 hour height of candle=4-0.6 inches
After 2 hours height of candle=4-0.6-0.6 inches
after x hours height of candle=4-0.6x
Also,
If the height of the candle after x hours is 1.5 inches
⇒ 4-0.6x=1.5
⇒ 0.6x=4-1.5
⇒ 0.6x=2.5
⇒ x=2.5/0.6
⇒ x=4.166
Hence, equation to represent the situation. is:
4-0.6x=1.5
and the expected number of hours in which the candle melted to 1.5 inches is:
4.166 hours
