Answer:

10/18

Step-by-step explanation:

To convert 1.8 to a reciprocal, you first need to change it into a fraction.

1.8 basically expresses 1 $\frac{8}{10}$ which equals $\frac{18}{10}$ .

Since a reciprocal is just switching the top and bottom of a fraction, your reciprocal of 1.8 will be $\frac{10}{18}$ .

You can simplify this if you want, to get $\frac{5}{9}$ . Either one is correct.

padilas [110]

Answer:

cost of a burger= $4.5

Cost of soda = $3.5

Cost of a slice of pizza = $5.5

Step-by-step explanation:

Let x = the cost of a burger.

Let y = the cost of a soda.

Let z = the cost of a slice of pizza.

Louis bought a burger and soda for $8. This means

x + y = 8 - - - - - - - -1

Kate purchased a slice of pizza and soda for $9. This means

z + y = 9 - - - - - - - - - 2

David purchased a burger, a slice of pizza, and a soda for $13.50. This means

x + y + z = $13.50 - - - - - - - 3

Substituting x = 8-y and z = 9-y in equation 3, it becomes

8-y + y + 9-y = 13.50

-y -y + y = 13.50 -8-9

-y = -3.5

y = $3.5

Put y = 3.5 in equation 1

x + 3.5 = 8

x = 8 - 3.5 = $4.5

Put x = 4.5 and y = 3.5 in equation 3.

4.5 + 3.5 + z = 13.5

8 + z = 13.5

z = 13.5 - 8 = $5.5

The sum of three times a number and 7 more than

dalvyx [7]

Answer:

3x+7+ x= -11-2x

4x + 2x = -11-7

6x = -18

x = -18/6

x = -3

therefore , the number is -3

now,

by putting value,

3x+7+x=-11-2x

3*(-3)+7+(-3)=-11-2*(-3)

-9+7-3=-11+6

-5=-5

82. A company spends x hundred dollars on an advertising

crimeas [40]

The company spends $649 on advertising

The sales function after advertising is given as:

$S(x) = 5 + 7\ln(x + 1)$

When the total sales is $19,100, we have S(x) = 19100

So, the sales function becomes

$5 + 7\ln(x + 1) = 19.1$

Subtract 5 from both sides

$7\ln(x + 1) = 14.1$

Divide both sides by 7

$\ln(x + 1) = 2.014$

Take exponents of both sides

$x + 1 = e^{2.014$

$x + 1 = 7.49$

Subtract 1 from both sides

$x= 6.49$

Hence, the company spends $649 on advertising
