Answer:
5
Step-by-step explanation:
Given that:
60km in 12 seconds
Distance α time
Distance = k * time
K = constant of proportionality
Distance = 60 ; time = 12 seconds
60 = 12k
60/12 = 12k/12
5 = k
Constant of proportionality is 5
18 increased by twice a number
Answer:
18+2x
Step-by-step explanation:
Let the number be x.
Translate: 2x + 18 = x - 4.
Subtract x from each side: x + 18 = -4.
Subtract 18: x = -22.
Check: 2(-22) + 18 = -44 + 18 = -26; -22 - 4 = -26.
8 increased by twice a number = 18+2x
What is a linear equation?A linear equation has one or two variables.
No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c. When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.solving this we will get the valve of Y if x is given.

Step-by-step explanation:
The cost of every college is expected to increase 3.5%
next year.
The cost to attend Faber College is currently $24000.
If the percentage increase stays constant, what will the
cost be in TWO years?
Answer:
25,709.4
Step-by-step explanation:
First you would multiply 3.5 x 24,000, and then divide by 100, to get 840, and then add that to the original amount to get 24,840, and that is the cost for one year. And then you would multiply 24,840 by 3.5 and then divide by 100 to get 869.4. Finally just add that to 24,840 to get 25,709.4, and that is the cost for 2 years. I hope this helps :)
The cost of college in two years is $25709.4.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Cost of Faber college = $24000
Rate of increase = 3.5%
The cost of college after one year.
= 103.5% of 24,000
= 103.5/100 x 24000
= $24,840
The cost of their college after two years.
= 103.5% of 24,000
= 103.5/100 x 24,840
= $25709.4
Thus,
The cost of college in two years is $25709.4.

Autumn invested $69,000 in an account paying an interest rate of 6 3/8% compounded continuously. Jayden invested $69,000 in an account paying an interest rate of 6 1/4% compounded quarterly. After 14 years, how much more money would Autumn have in her account than Jayden, to the nearest dollar?
Answer:
4,038.21
Step-by-step explanation:
I'm going to assume that when you write 6 3/8% that equals 51/8%=6.375%
To find the value in the first equation we have
69000*e^(.06375*14)=168,444.5313
The second equation is as follows
69000(1+(.0625/4))^(14*4)=164,406.3243
Subtract the two and get 4,038.2071

Answer:
Addition property of equality
Step-by-step explanation:
The given expression is :
[tex]\dfrac{x}{4}-\dfrac{3}{4}=16[/tex]
We need to find the first step to solve this expression.
For this, we add 3/4 to both sides of the equation i.e.
[tex]\dfrac{x}{4}-\dfrac{3}{4}+\dfrac{3}{4}=16+\dfrac{3}{4}\\\\\dfrac{x}{4}=16+\dfrac{3}{4}[/tex]
So, we have used the addition property of equality.

Five friends share 3 pizzas equally.How much pizza does each friend get?
Answer:
Each friend gets 3 slices each.
Step-by-step explanation:
Solve this problem, and identify the percent, amount, and base.
What percent of 60 is 45?
The percentage is 75%, the amount is 45 and the base is 60 so option (D) will be correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
Given that 45 is some percentage of 60
So, 60 will be the base because we are calculating the percentage of it and the amount will be 45.
Let's say 45 is x percentage of 60
Then,
60 × x/100 = 45
x = 4500/60
x = 75%
Percentage will be 75
Hence "The percentage is 75%, the amount is 45 and the base is 60".
