Answer:

the solution is (4, 1).

Step-by-step explanation:

The goal here is to "solve this system of linear equations." You need to share that along with the equations.

We can begin the solution by substituting 3y + 1 for x in the second equation:

2(3y + 1) + 4y = 12

Performing the multiplication, we get 6y + 2 + 4y = 12, or 10y = 10.

Then y must be 1.

Substituting 1 for y in the first equation, we get x = 3(1) + 1 = 4

Thus, the solution is (4, 1).

Answer:

The answer to your question is: ∠K = 138°

Step-by-step explanation:

m∠N = 42°

m∠K = ?

The sum of all the internal angles in a quadrangle equals 360°

then

∠N + ∠L + ∠M + ∠K = 360°

∠N = ∠ L and ∠M = ∠K

So, 2 ∠N + 2 ∠K = 360

Substitution

2 (42) + 2 ∠K = 360

84 + 2 ∠K = 360

2 ∠K = 360 - 84

2 ∠K = 276

∠K = 276 / 2

∠K = 138°

5. Maria is tracking the number of miles she runs in one week. She is using the track at her

777dan777 [17]

Answer:

0.00310 miles

Step-by-step explanation:

Maria runs 5 m each week. We need to find how miles she run. It means we need to convert meters to miles. The relation between meter and yards is as follows :

1 meter = 1.09361 yards

Also, 1 mile = 1760 yards

It means,

1 mile = 1609.34 m

1 m = (1/1609.34) miles

$5\ m=\dfrac{5}{1609.34}\ \text{miles}\\\\=0.00310\ \text{miles}$

So, she will cover 0.00310 miles.

Do i need to flip the reciprocal please explain your answer<br> 2y/2 < 10/2

Answer:

$\displaystyle \large \boxed{y < 5}$

Step-by-step explanation:

We are given the Inequality:

$\displaystyle \large{ \frac{2y}{2} < \frac{10}{2} }$

First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.

Simply, division!

$\displaystyle \large{ \frac{ \cancel{2}y}{ \cancel{2}} < \frac{ \cancel{10}}{ \cancel{2} }}$

2 divides 2 is 1; 2 divides 10 is 5.

$\displaystyle \large{ \frac{1y}{1} < \frac{ 5}{ 1}}$

Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.

Simplify the expression:-

$\displaystyle \large{ y < 5}$

Therefore, the value of y is less than 5.

Let me know if you have any questions after reading the explanation!

Answer:

-1/36

Step-by-step explanation:

-5/18 - ( -1/4)

Subtracting a negative is like adding

-5/18 + 1/4

Getting a common denominator of 36

-5/18 *2/2 + 1/4 *9/9

-10/36 + 9/36

-1/36
