Answer:

-19

Step-by-step explanation:

3x+2 = -55

-2 -2

3x = -55-2

3x = -55+-2

3x = -57

/3 /3

x=-19

Answer:

-19

Step-by-step explanation:

$3x + 2 = -55$

$3x = -55$

$-2$ (2 is negative because it was moved to the other side of the equation)

$3x/3 = -57/3$ (Divide both sides of the equation by 3 to isolate x.)

$x = -19$

Find the values of x, y, and z. The diagram is not to scale.

Kruka [31]

we know that

The sum of the internal angles in the triangle must be $180$ degrees

see the attached figure with letters to better understand the problem

Step $1$

<u>Find the measure of the angle x</u>

In the triangle ABC

$63\°+36\°+x\°=180\°$

solve for x

$99\°+x\°=180\°$

$x\°=180\°-99\°$

$x=81\°$

therefore

<u>the answer Part a) is</u>

the measure of angle x is $81\°$

Step $2$

<u>Find the measure of the angle z</u>

we know that

$x+z=180\°$ --------> by supplementary angles

substitute the value of x

$81\°+z=180\°$

$z=180\°-81\°$

$z=99\°$

therefore

<u>the answer Part b) is</u>

the measure of angle z is $99\°$

Step $3$

<u>Find the measure of the angle y</u>

In the triangle ACD

$13\°+z\°+y\°=180\°$

solve for y

$13\°+99\°+y\°=180\°$

$112\°+y\°=180\°$

$y\°=180\°-112\°$

$y\°=68\°$

therefore

<u>the answer Part c) is</u>

the measure of angle y is $68\°$

Megan's family had cakes on two days. The first day, they had 2 3/4 cakes left. The second day, they had 1 1/4 cakes left. How m

vlabodo [156]

Answer: 4 cakes left in all.

Step-by-step explanation:

Given: Cakes left on first day= $2\frac{3}{4}=\frac{11}{4}$

Cakes left on second day = $1\frac{1}{4}=\frac{5}{4}$

The number of cakes left in all= $\frac{11}{4}+\frac{5}{4}$

⇒The number of cakes left in all= $\frac{11+5}{4}=\frac{16}{4}$

Therefore, The number of cakes left in all=4

Please help im stuck on this question

VARVARA [1.3K]

Answer:

(12,0)

Step-by-step explanation:

slope m=

$\frac{54-36}{27-22} =\frac{18}{5}$

$y-36=\frac{18}{5}(x-22)\\\\5y-180=18x-396\\\\y=\frac{18x}{5} -\frac{46}{5}$

$0=\frac{10}{5}x-\frac{46}{5}\\\\x=\frac{216}{18} =12$

hope it helps...
