Find an ordered pair of 5x + y = 3

Mathematics

1 answer:

Rufina [12.5K]3 years ago

7 0

Answer:

Step-by-step explanation:

Find an ordered pair that satisfies the equation 5x + y = 3.

There are infinitely many ordered pairs that satisfy this equation.

If we were to choose y = 0, then 5x = 3, and x = 3/5, leading to the ordered pair (3/5, 0).

If we were to choose x = 1, then 5(1) + y = 3, or y = -2. The ordered pair would be (1, -2).

And so on.

Jill, Meg and Beth are sister's. Jill is 2 years younger than Meg. Beth is half as old as Meg. Let m represent Meg's age. Write

pshichka [43]

Answer:

Two other algebraic expressions based on this situation are:

$J = m-2$

$B = \frac{m}{2}$

Step-by-step explanation:

Let m represent Meg's age.

Jill is 2 years younger than Meg.

Let J represents Jill's age

Jill's age $J = m-2$

Beth is half as old as Meg

Let B represents Beth's age

Beth's age $B = \frac{m}{2}$

So, two other algebraic expressions based on this situation are:

$J = m-2$

$B = \frac{m}{2}$

Pie

Answer:

$7.10

Step-by-step explanation:

Step 1: We make the assumption that 35.5 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=35.5$.

Step 4: In the same vein, $x\%=20$.

Step 5: This gives us a pair of simple equations:

$100\%=35.5(1)$.

$x\%=20(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

Step 7: Taking the inverse (or reciprocal) of both sides yields

If 3 = 1/2gt^2, make t the subject of the formula<br>

Montano1993 [528]

Answer:

t = √1.5/g

Step-by-step explanation:

1/2gt^2 = 3

Divide both sides by 1/2

gt^2 = 1.5

Divide both sides by g

t^2 = 1.5/g

Square root both sides

t = √1.5/g

What is one third the difference between 3/4 and 2/3?

Ivan

Answer:

One third the difference between 3/4 and 2/3 is $(\frac{1}{36} )$

Step-by-step explanation:

One third the difference of A and B = $\frac{1}{3} \times (A-B)$

Here, as given in the question:

$A = \frac{3}{4} , B = \frac{2}{3} \\\implies A - B = \frac{3}{4} - \frac{2}{3}\\=(\frac{3 \times 3 -2 \times 4}{12}) = (\frac{9-8}{12} ) = (\frac{1}{12})\\ \implies A - B = (\frac{1}{12})$

Now, one third of the difference is :

$(\frac{1}{3}) \times (\frac{1}{12}) = (\frac{1}{36})$

Hence, one third the difference between 3/4 and 2/3 is $(\frac{1}{36} )$
