Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

A) Let's solve for x. $-3x-7y=-66$

Step 1: Add 7y to both sides.

$-3x - 7y + 7y = -66 + 7y \\-3x = 7y - 66$

Step 2: Divide both sides by -3.

$\frac{-3x }{-3} = \frac{7y - 66}{-3}$

$x = \frac{-7}{3}y + 22$

Answer : $\frac{-7}{3}y + 22$

~~~~~~~~~~~~~

B) Let's solve for x. $-10x-7y=-24$

Step 1: Add 7y to both sides.

$-10x - 7y + 7y = -24 + 7y \\-10x = 7y - 24$

Step 2: Divide both sides by -10.

$\frac{-10x}{-10} = \frac{7y - 24}{-10}$

$x = \frac{-7}{10}y + \frac{12}{5}$

Answer : $\frac{-7}{10}y + \frac{12}{5}$

In triangle XYZ, the measure of angle X is 84, the measure of angle Y is (r + 59) and the measure of angle z is (r + 51), find t

xenn [34]

Answer:

r = -7
Y = 52°

Step-by-step explanation:

The sum of the measures of the angles in a triangle is 180°.

X + Y + Z = 180°

84° +(r +59)° +(r +51)° = 180°

2r +194 = 180 . . . . . . . . . divide by ° and simplify

2r = -14 . . . . . . . . . . subtract 194

r = -7

Then the measure of Y is ...

Y = (r +59)° = (-7 +59)°

Y = 52°

Additional comment

Z = 44°

Can a positive and negative number be equivalent and plz explain you know it

Sunny_sXe [5.5K]

Answer:

Yes! See explanation below!

Step-by-step explanation:

If a positive and negative number is equivalent, then they are called additive opposites meaning they add up to 0, basically cancelling out.

Ex:

$1+-1=0\\1000000+-1000000=0\\\frac{1234}{1234}+-\frac{1234}{1234}=0$

Perfect pizza has 16 toppings listed on their menu. how many ways could a customer choose a pizza that contains 5 different topp

marishachu [46]

Answer:

4368 ways

Step-by-step explanation:

Use nCk for this. 16C5. This is $\frac{n!}{(n-k)!(k!)}$ . This becomes $\frac{16!}{(11!)(5!)}$ . This is $\frac{16*15*14*13*12}{5*4*3*2*1}$ due to 16! and 5! canceling out. This becomes 4368.
