As per the problem

Soda is on sale for $0.50.

and you have a coupon for $0.80 off your total purchase.

we are supposed to write a function rule for the cost of an can of soda.

If you buy x cans of soda then the cost function can be written as

$C(x)=0.5x-0.80\\ \\ \text{we can replace x by the number of cans, here we have x=1 }\\ \\ C(1)=0.50*1-0.80$

Jace has consumed 1,500 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily c

Ghella [55]

Answer:

800 calories

Step-by-step explanation

Jace wants his total to be: 1,900

He consumed: 1,500

He burned: 400

How much is left: ?

Your equation would look like: 1900=1500-400+x

First step is to add like terms so: 1500-400= 1100

Now you subtract the calories Jace has gained with the total he wants to achieve: 1900-1100= 800

The amount he needs to gain is: x=800

1,100 is not aa viable solution because he want to keep his calory intake at 1,900, and 1,100 is the total for the calories he already consumed and burned while at the gym.

Hope this made sense!

The sum of the digits of a two-digit number is 8. The difference between the number and the reversed number is 10 more than the

Vesna [10]

Answer:

The number is 62

Step-by-step explanation:

Let the digits of the number be T and U;

A 2 digit number is represented as: 10T + U

So,

$T + U = 8$

$10T + U - (10U + T) = 10 + 10U + T$

Required

Find the digit

Make U the subject in the first equation

$U = 8 - T$

Substitute 8 - T for U in the second

$10T + U - (10U + T) = 10 + 10U + T$

$10T + 8 - T - (10*(8-T) + T) = 10 + 10(8 - T) + T$

$10T + 8 - T - (80-10T + T) = 10 + 80 - 10T+ T$

$10T + 8 - T -80+10T - T = 10 + 80 - 10T+ T$

Collect Like Terms

$10T + 10T - T- T + 8 -80 = 10 + 80 - 10T+ T$

$18T -72 = 90 - 9T$

$9T + 18T = 90 + 72$

$27T = 162$

$T = 162/27$

$T = 6$

Recall that:

$U = 8 - T$

$U = 8 - 6$

$U = 2$

<em>Hence, the number is 62</em>
