The following set of coordinates represents which figure?

One step inequalities.... 9x<18<br> how to solve

Nuetrik [128]

So 9x<18 can be factored out into
9(x)<9(2)
you can divide both sides by 9
x<2

so the solution is any number more than 2, but not 2

The owner of a grocery store wants to mix two types of candy together to make 15 lbs that he he can sell for $5.00 per lb. He wa

Anestetic [448]

Answer:

9 pounds of chocolate and 6 pounds of sugar candies

Step-by-step explanation:

Let's define the variables:

C = pounds of chocolate candies used.

S = pounds of sugar candies used.

We know that he wants to make a total of 15lb, then:

C + S = 15

We also want that the price per pound to be equal to 5$.

This means that the price of the 15 pounds will be the same as the price of the un-mixed candies.

C*$7.00 + $2.00*S = $5.00*15

Then we have a system of equations:

C + S = 15

C*$7.00 + $2.00*S = $5.00*15

To solve this system, we need to start by isolating one of the variables, i will isolate C in the first equation:

C = 15 - S

now we can replace that in the other equation:

(15 - S)*$7.00 + $2.00*S = $5.00*15

Now we can solve this for S.

$105 - $5.00*S = $75

$105 - $75 = $5.00*S

$30 = $5.00*S

$30/$5 = S = 6

Then there are 6 pounds of sugar candy, and we can use the equation:

C + S = 15

C + 6 = 15

C = 15 - 6 = 9

There are 9 pounds of chocolate candy in the mix.

Proximately 32, 800 citizens of the country died in my automobile accident in 2015. Expressed this toll in deaths per day

Anton [14]

Remark
2015 is an odd numbered year. It is not a leap year. It has 365 days in it.

Equation
Total deaths = deaths / day * number of days

Givens
Total deaths = 32800
deaths / day = ???
number of days = 365

Sub and solve
32800 = x * 365 Divide by sides by 365
32800 / 365 = x
x = 89.86 deaths per day.

Problem
Do you round up, down or leave the number as it is?

I would round up 90 deaths per day.

Discussion
Just how much are you out?
Total deaths in a year (rounded) = 90 * 365
Total deaths in a year (rounded)= 32850 which is 50 too many

Suppose you round down
Total death/day = 89 * 365 = 39485 Rounding up is going to be better if you round at all.

Perhaps you should not round the answer at all and leave it at
89.86 <<<<< answer.
If you have choices, please list them.

Answer:

Investigation 7 introduces a method for computing the ... at a constant rate with respect to the measure of another, then the changes in the ... –5.2 = –3.1∆x ... y = 3.6 + (5.1/–3.5)(x – 12.2) or y = –1.5 + (5.1/–3.5)(x – 8.7).
