Which ordered pair (c, d) is the solution to the given system of linear equations?
sasho [114]

Answer:

(-1,6)

Step-by-step explanation:

The missing part of this question is the system given as;

-c+2d=13

-9c-4d=-15

We solve for c in the top equation to get:

c=2d-13

Substitute c=2d-13 into the bottom equation to get:

-9(2d-13)-4d=-15

Expand to get:

-18d+117-4d=-15

Group similar terms to get:

-18d-4d=-15-117

-22d=-132

d=6

Put d=6 into c=2d-13 to get:

c=2*6-13

c=12-13=-1

The solution is (-1,6)

grade 5 math. How would I write a ratio for a project when asked to compare prices from two stores, IE 32 slices of texas toast
REY [17]
To compare, think of the ratios as a fraction. so it is 32 slices per $7.99.
You can also say $7.99 per 32 slices.
so it can be  ̲7̲.̲9̲9̲ ̲   or the other way around.
                       32
To find the unit price, or the price of 1 item, you have to divide the price by the amount.
So 7.99 divided by 32 is <span>0.249687, but we don't have thousandths of a cent, so we round to the hundredth.
$0.25 is the unit price, or the price of 1 toast, rounded to the nearest cent.

So let's try another one, this time we have 2 different rates, and we will compare them.

So let's say we are buying cheese. Store A sells 12 blocks of cheese for $14.99, and Store B sells 20 blocks for $23.99.
So first we have to find the unit rate for each.

             Store A                                 Store B
         14.99 per 12                        23.99 per 20
                                         
             </span> ̲1̲4̲.̲9̲9̲ ̲                                  ̲2̲3̲.̲9̲9̲ ̲<span>
                 12                                         20

14.99 / 12 is </span>1.24916                    23.99 / 20 is <span>1.1995</span>
<span>$1.25, if rounded to the cent.    $1.20, if rounded to the cent
</span>1 block is $1.25 in Store A.         1 block is $1.20 in Store B

Store B sells for cheaper.

Hope that helps.
