Line A: 2x + 2y = 8

Line B: x + y = 4


Multiply line B by 2

Line B: 2x +2y = 8


Now you have:

Line A: 2x + 2y = 8

Line B: 2x +2y = 8

--------------------------------subtract

0 = 0


Answer

There are infinitely many solutions.

S=2c AND s-16=c+16
Use substitution so...
2c-16=c+16
C=32
S=2c so s=64

Check: s-16=c+16...64-16=32+16...48=48

So Cassandra is 32 and Seymour’s is 64

A population of 900 voters contains 369 Republicans, 468 Democrats, and 63 independents and members of other parties. A simple r
UkoKoshka [18]

Answer:

Step-by-step explanation:

Total voters = 900

Republicians =369

Democrats =468

Independents = 63

Sample size n =90

a) The expected value of the number of Republicans in the sample is

=\frac{90*369}{900} =36.90

b) The chance the sample contains only Republicans and Democrats is

= (no of republicians+democrats)/total people

=\frac{369+468}{900} =0.93

Linda saves $1.55 every day. Tyron saves $3.90 every day. Linda started saving 3 days earlier than Tyron. On which day will Tyro
madreJ [45]
Step 1: Write the amount of savings in equation
Linda's savings: s=1.55d
Tyron's savings: m=3.90d

Step 2: Add on the extra days to Linda's savings
Linda's savings s=1.55d+3(1.55)

Step 4: Simplify equation
s=1.55d+3(1.55)
s=1.55d+4.66

Step 5: Substitute numbers for d days until Tyron's m savings is greater than Linda's s saving
m=3.90d s=1.55(2)+4.66
m=3.90(2) s=3.10+4.66
m=7.80 s=7.76

On Tyron's second day he will have more money in his savings than Linda does.

faltersainse [42]

Answer:

The amount that should be in the account after 15 years is $95,321.85

Step-by-step explanation:

According to the given data, we have the following:

monthly amount of $220=R

interest rate is fixed at 2.05%. We require the monthly ineterest rate, hence monthly interest rate= 2.05%/12=0.1708%=0.0017

t=15years×12=180 months

In order to calculate how much should be in the account after 15 years, we would have to use the following formula:

Ap=<u>R(1-(1+i)∧-t)</u>

             i

Ap=<u>220(1-(1+0.0017)∧-180)</u>

                       0.0017

Ap=<u>162,04</u>

      0.0017

Ap=$95,321.85

The amount that should be in the account after 15 years is $95,321.85
