NEED HALP!!! Find the ordered pair $(s,t)$ that satisfies the system
satela [25.4K]

Answer:

(-8/7 ; 5/7)

Step-by-step explanation:

5t + 1/2s = 3 - - - (1)

3t - 6s = 9 - - - - - (2)

Multiply (1) by 12 and (2) by 1

Add the result to eliminate s

60t + 6s = 36

3t - 6s = 9

____________

63t = 45

t = 45 / 63

t = 5/7

Put t = 5/7 in either (1) or (2) to obtain the value of s

3(5/7) - 6s = 9

15/7 - 6s = 9

-6s = 9 - 15/7

-6s = (63 - 15)/7

-6s = 48/7

s = 48/7 * - 1/6

s = - 8/7

How many teaspoons of brine shrimp every day? There are about 125,000 Brine shrimp in 1 pound. A pound contains 96 teaspoons. A
sveticcg [70]

Answer:

2\frac{38}{125}\ teaspoons

Step-by-step explanation:

we know that

There are about 125,000 Brine shrimp in 1 pound

1 pound contains 96 teaspoons

so

There are about 125,000 Brine shrimp in 96 teaspoons

Using proportion

Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp

Let

x -----> the number of teaspoons

\frac{96}{125,000}=\frac{x}{3,000}\\\\x=3,000(96)/125,000\\\\x=\frac{288,000}{125,000}\ teaspoons

Simplify

\frac{288}{125}\ teaspoons

Convert to mixed number

\frac{288}{125}\ teaspoons=\frac{250}{125}+\frac{38}{125}=2\frac{38}{125}\ teaspoons

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 4, 14, 16, 4, 20, 19, 12
marysya [2.9K]
The mean is simply the average of the total movies seen so..
\frac{4 + 14 + 16 + 4 + 20 + 19 + 12 + 10}{2} = mean
\frac{99}{2} = mean
49.5 = mean

the median is the middle number (or the average of the middle 2 numbers)
so if we line up the numbers in order and cross them out from both ends we get 12 & 14 so we take the average of the 2
13 = median

Dakota has \dfrac4{10} \text { kg} 10 4 ​ kgstart fraction, 4, divided by, 10, end fraction, start text, space, k, g, end text o
Savatey [412]

Answer:

There are <u>2.22 grams</u> of clay are in each pot.

Step-by-step explanation:

Given:

Dakota has 4/10 kg of clay. He divides the clay to make 888 equal-sized pots.

Now, to find the number of grams of clay are in each pot.

Dakota has clay = \frac{4}{10} \ kg.

So, by using conversion factor we convert it into grams:

\frac{4}{10} \times 1000\\\\=\frac{4000}{10} \\\\=400\ grams.

Quantity of clay he has = 400 grams.

Number of equal-sized pots to make = 888.

Now, to get the quantity of grams of clay are in each pot we divide number of equal-sized pots to make by quantity of clay he has:

\frac{888}{400}

=2.22\ grams.

Therefore, there are 2.22 grams of clay are in each pot.
