Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.
EleoNora [17]

Answer:

The system of equation are \left \{ {{15+1x} \atop {3+5x}} \right..

In <u>3</u> weeks, the friends will each have passed <u>18</u> scales.

Step-by-step explanation:

Let number of weeks be 'x'.

Given:

Number of scale Pablo has passed = 15 scales

Number of scale Kayla has passed = 3 scales

Number of scales passing per week by Pablo = 1 scale

Number of scales passing per week by Kayla = 5 scale

We need find the number of weeks when both have same scales.

First we will find the Total number of scales Pablo will passed after 'x' weeks.

Total number of scales Pablo will passed after 'x' weeks is equal to sum of Number of scale Pablo has passed and Number of scales passing per week by Pablo multiplied by number of weeks.

framing in equation form we get;

Total number of scales Pablo will passed after 'x' weeks = 15+1x

Now we will find Total number of scales Kayla will passed after 'x' weeks.

Total number of scales Kayla will passed after 'x' weeks is equal to sum of Number of scale Kayla has passed and Number of scales passing per week by Kayla multiplied by number of weeks.

framing in equation form we get;

Total number of scales Kayla will passed after 'x' weeks = 3+5x

Hence the system of equation are \left \{ {{15+1x} \atop {3+5x}} \right..

Now we need to find the number of weeks when both have passed equal scales.

Hence we can say that;

Total number of scales Pablo will passed after 'x' weeks = Total number of scales Kayla will passed after 'x' weeks

Substituting the value we get;

15+1x=3+5x

On Solving the equation we get;

Combining like terms first;

5x-x=15-3\\\\4x=12

Now by Division property dividing both side by 4 we  get;

\frac{4x}{4}=\frac{12}{4} \\\\x=3 \ weeks

Now we will find the total scales passed by each after 3 weeks;

Total number of scales Pablo will passed after 3 weeks = 15+x=15+3 = 18 \ scales

Total number of scales Kayla will passed after 3 weeks = 3+5x=3+5\times3 = 18 \ scales

Hence: In <u>3</u> weeks, the friends will each have passed <u>18</u> scales.

How much interest would $1,000 earn in 1 year at an annual rate of 2% compounded annually
NNADVOKAT [17]

The Compound Interest would be $1104.895

What is Compound Interest ?

The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound and simple interest is this. If we examine our bank statements, we will typically see that our account is credited with interest on a yearly basis. Even though the principal remains the same, the interest changes annually. We can observe that interest rises over time. As a result, we can infer that the interest the bank charges is compound interest, or CI, rather than simple interest.

Number of quarters in 5years =5×4=20

Quarterly rate of compound interest

r=24=0.5%

Initial amount

P=$1000

hence the total amount after 5years

=  P(1+r/100)n

=1000(1+0.5/100)^20

=1000(1.005)^20

=$1104.895

Hence, The Interest will be $1104.895

Rafael Drive 405 miles using 20 gallons of gas. At that rate, how many gallons of gas would he need to drive 243 miles?
ANEK [815]
This is how I'd set it up:
405/20 = 243/x 
this means the mpg (miles / gallons) for 1 situation is the same as the mpg for the other situation (because the rate is the same)
then just cross multiply and solve:
405x=243*20 or 405x=4860 or x = 12
he would need 12 gallons of gas for 243 miles
