8 0

Answer:

See below.

Step-by-step explanation:

So we have the equation:

$7m+11=-4(2m+3)$

Distribute the right:

$7m+11=-8m-12$

Add 12 to both sides:

$7m+23=-8m$

Subtract 7m from both sides:

$23=-15m$

Divide by -15:

$m=-23/15\approx-1.5333$

Write 2/10 in simplest form?

Artyom0805 [142]

2/10 in simplest form:

First, we can start out by finding the greatest common factor (GCF) of the numerator (2) and the denominator (10). This should always be done when simplifying a fraction the quickest way. Let's list out the factors of each number and find the common ones.

Factors of 2: 1, 2
Factors of 10: 1, 2, 5, 10

The GCF is 2, considering that 1 and 2 are the common factors, but 2 is the greatest.

Second, our last step is to divide our numerator and denominator by the GCF (2) to find out our simplified fraction.

$2 \div 2 = 1 \\ 10 \div 2 = 5$

Answer in fraction form: $\fbox {1/5}$
Answer in decimal form: $\fbox {0.2}$

-4x-2y=30<br> 1/3y=7/3x+5/3<br> we are supposed to use substitution when solving

seropon [69]

Answer:

The solution set is (-20/9, -95/9)

Step-by-step explanation:

To solve using the substitution method, start by solving the second equation for y.

1/3y = 7/3x + 5/3

y = 7x + 5

Now that we have this, we can plug it in for y in the first equation. Then we can solve for x.

-4x - 2(7x + 5) = 30

-4x - 14x - 10 = 30

-18x - 10 = 30

-18x = 40

x = -20/9

Now that we have the value of x, we can solve for y by inputting the x value into either equation.

-4x - 2y = 30

-4(-20/9) - 2y = 30

80/9 - 2y = 30

80/9 - 2y = 270/9

-2y = 190/9

y = -95/9

What is the distance between(-3,-8) and (-12,-11)

Ira Lisetskai [31]

Step-by-step explanation:

Use the distance formula:

d² = (x₂ − x₁)² + (y₂ − y₁)²

d² = (-3 − -12)² + (-8 − -11)²

d² = 9² + 3²

d² = 90

d = 3√10
