Answer:
58.75 degreeF
Step-by-step explanation:
The initial temperature of the Soda = 40degreeF
The temperature outside is steady at 99 degreeF
The temperature of the soda became 50 degreeF after 8 minutes
In 8 minutes, the Soda gained
(50 - 40)degreeF
= 10 degreeF
If the soda gains 10 degreeF in 8 minutes, in 1 minute, it will gain 10/8degreeF
Therefore in 7 minutes, the soda will gain (10/8)*7
= 70/8
= 8.75 degreeF
The expected temperature of soda after an additional 7 minutes = 50 + 8.75
= 58.75degreeF
Answer:
A
Step-by-step explanation:
The correct answer is Option C. Ty saved $14 and he earns $9 each week. How many weeks will it take till he has $100?
Further explanation:
Given equation is:
9x+14
We will look at the options one by one
<u>A.9 dogs and 14 dogs and 14 cats cost $100</u>
If this option has to be considered, there will be atleast two variables involved one for the dogs and one for the cats while the given equation only involves one variable so this is not the correct option.
<u>B. Ty wants to buy 14 dogs, but they cost $100, how much more does he need?</u>
The given scenario cannot be linked to given equation if x represents dogs the equation will be something like 14x=100 so this option is not the correct answer.
<u>C. Ty saved $14 and he earns $9 each week. How many weeks will it take till he has $100?</u>
The number 14 will be constant as this is the value which is used only once while ty earns 9 dollar per week if x represents number of weeks then the equation to represent the scenario will be
9x+14=100
The value of x will give us the number of weeks required.
The correct answer is Option C. Ty saved $14 and he earns $9 each week. How many weeks will it take till he has $100?

Answer:
Step-by-step explanation:
Given expression
To solve for 
for the given expression.
Solution:
We multiply each term with the least common multiple of the denominators of the fraction in order to remove fractions.
The multiples of the denominators are:
3 = 3,6,9,<u>12</u>,15
6 = 6,<u>12</u>
4 = 4,8,<u>12</u>
The least common multiple = 12.
Multiplying each term with 12.
Using distribution.
Simplifying.
Adding 
both sides.
Adding 51 both sides.
Dividing both sides by 15.
Simplifying fractions.
