this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5

1)We solve the first equation:
2x-1=5
2x=5+1
2x=6
x=6/2
x=2

2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2

The solutions of this equation /2x-1/=5 will be: x=3 and x=-2

Answer: x=3 and x=-2

Answer:

Step-by-step explanation:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

there's 10

1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15

1 + 9 = 10

10 + 10 = 20

2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15

2 + 8 = 10

20 + 10 = 30

3, 4, 5, 6, 7, 11, 12, 13, 14, 15

3 + 7 = 10

30 + 10 = 40

4, 5, 6, 11, 12, 13, 14, 15

4 + 6 = 10

40 + 10 = 50

5, 11, 12, 13, 14, 15

5 + 15 = 20

50 + 20 = 70

11, 12, 13, 14

11 + 14 = 25

70 + 25 = 95

12, 13

12 + 13 = 25

95 + 25 = 120

she would 120 nickels which is

120 x 5 = 600 cents or $6

Lucy has a goal of walking at least 15 miles she walks at a rate of 5 miles per hour which inequality can Lucy used to find H th

elena55 [62]

Answer:

5h>15

Step-by-step explanation:

✓From the question, we were informed that Lucy walks at a rate of 5 miles per hour, this implies that 5 is multiplied by amount of hours (5×1h)= 5h

✓ we need to find the inequality that Lucy can use to find H the number of hours she should walk in order to meet or exceed her goal, To find this as equation, we know that Lucy must walk for at least 15 miles which implies that the (5h) will always be greater than 15 miles. We can put it in equation as

5h>15

NOTE: Inequality provide the relation that exist between two unequal expression. Using notation such as

What is the area of the figure ?

vodka [1.7K]

Answer:

48cm^2

Step-by-step explanation:

We can break the composite figure into two pieces.

We take the bottom rectangle and determine its area

The figure is 10 cm by 2 cm

A = 10*2 = 20cm^2

The height of the vertical rectangle is 9 cm -2 cm = 7 cm

The width is 10 cm - 6 cm = 4 cm

The figure is 7 cm cm by 4 cm

A = 7*4 = 28cm^2

The total area is the sum of the two areas

20 cm^2 + 28 cm^2 = 48 cm^2

$1,000 is invested at a rate of 3.25%, compounded annually. Identify the compound interest function that models the situation. T

Ulleksa [173]

The compounded interest function that models the situation is: $A=P(1+ \frac{r}{n} )^{nt}$
where
$A$ is the final amount of money after $t$ years.
$P$ is the initial investment.
$r$ is the interest rate in decimal form.
$n$ is the number of times the interest is compounded per year.
$t$ is the time in years.

We know for our problem that $P=1000$ and $t=8$ . To convert the interest rate to decimal form, we are going to divide the rate by 100%:
$r= \frac{3.25}{100}$
$r=0.0325$
We also know that the interest is compounded anally, so it is compounded 1 time per year; therefore, $n=1$ .
Lets replace the values in our formula to find the final amount after 8 years:
$A=P(1+ \frac{r}{n} )^{nt}$
$A=1000(1+ \frac{0.0325}{1} )^{(1)(8)}$
$A=1000(1+ 0.0325 )^{8}$
$A=1291.58$

We can conclude that since we are dealing with compound interest we must use the function $A=P(1+ \frac{r}{n} )^{nt}$ . Also, after 8 years the balance in the account will be $1291.58
