The difference between two numbers is 14. if 1/3 of the larger number is subtracted from the smaller number ,the result equals 1

otez555 [7]

Answer:

Step-by-step explanation:

x-y=14

x-1/3y=1/10

-y=14-x

y=-14+x

take out the factors

x-10/30y=3/30

30x-10y=3

substitute

30x-10(-14+x)=3

30x+140-10x=3-140

20x/20=-137/20

x=-6.85

y=-14+(-6.85)

y=-20.85

Please help with number 5?

Flauer [41]

Unsure how your teacher wants the table to be filled out, but the solution is about 1.62.

$x = 1.75, f(x) =1.0625, g(x) =.75 \\ \\ 
x = 1.64, f(x) =.6896, g(x) =.64 \\ \\ 
x = 1.63, f(x) =.6569, g(x) =.63 \\ \\ 
x = 1.62, f(x) =.6244, g(x) = .62 \\ \\ 
x = 1.61, f(x) = .5921, g(x) = .61$

Masja [62]

Answer:

There are 47.12 liters in 12.4 gallons of gasoline.

Option C is correct option.

Step-by-step explanation:

Total Gasoline bought = 12.4 gallons

We are given:

1 gallons = 3.8 liters

So.=, we need to find how many liters in 12.4 gallons of gasoline

1 gallon = 3.8 liters

12.4 gallon = 3.8*12.4

= 47.12 liters

So, there are 47.12 liters in 12.4 gallons of gasoline.

Option C is correct option.

Lyn invested $7,000 into a investment paying 3% interest, compounded semi-annually, twice a year. After five years, how much wou

gayaneshka [121]

Answer:

Option B.) $8,123.79

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=5\ years\\ P=\$7,000\\ r=0.03\\n=2$

substitute in the formula above

$A=\$7,000(1+\frac{0.03}{2})^{2*5}$

$A=\$7,000(1.015)^{10}=\$8,123.79$
