4x - 5y = 20 , what are the steps for solving for y?

Colt1911 [192]

Answer:

Check explanation below!

Step-by-step explanation:

» <u>Solving</u>

Step 1: Subtract 4x from both sides.

$4x-5y-4x=20-4x$
$-5y=-4x+20$

Step 2: Divide both sides by -5.

$\frac{-5y}{-5} = \frac{-4x+20}{-5}$
$y=\frac{4}{5}x-4$

Given: 15+6(y−2)=21 Prove: y = 3 Drag and drop the reasons into the boxes to correctly complete the proof. Statement Reason 15+6

olchik [2.2K]

Answer:

Given: $15+6(y-2)=21$

Distributive Property tells us that we multiply each term inside the parentheses with the term outside of the parentheses.

$a\cdot(b-c) =a\cdot b -a\cdot c$

Using distributive property on expression 6(y-2) to solve the further expression as:

$15+6\cdot y - 6\cdot 2=21$

Simplify:

$15+6y-12 =21$

Subtract the number 12 from 15 we get 3;

therefore, the expression become:

$6y+3=21$

Subtraction property of equality tells us that subtract the same number from both sides of an equation.

Now, subtract 3 from both the sides we get;

$6y+3-3=21-3$

Simplify:

$6y=18$

Now, divide by 6 on both the sides we get;

$\frac{6y}{6}= \frac{18}{6}$

On simplify we get;

y =3 Hence Proved!

Given m∠JML = 80 and m∠KML = 33, what is m∠JMK

Harrizon [31]

Answer:

Step-by-step explanation:

Given m∠JML = 80 and m∠KML = 33, to calculate the value of angle m∠JMK, we will apply the formula since all the angles are all acting at point M.

m∠JML = m∠JMK+m∠KML

Substituting the values given into the equation;

80 = m∠JMK + 33

subtract 33 from both sides of the equation

m∠JMK = 80-33

m∠JMK = 47°

<em>Hence the value of angle m∠JMK is 47°</em>
