Firdavs [7]3 years ago
3 0

Step-by-step explanation:

Equation of line in slope point form is given as:

y - y_1 = m(x-x_1)  \\ y - 5 =  \frac{1}{3}(x + 2) \\ y - 5 =  \frac{1}{3} x +  \frac{2}{3}  \\ y = \frac{1}{3} x +  \frac{2}{3} + 5 \\ y = \frac{1}{3} x +  \frac{2 + 3 \times 5}{3} \\  \\  \red { \bold{y = \frac{1}{3} x +  \frac{17}{3} }}\\

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\°

A grocery store recieves a 180-pound crate containing six 10-pound bags of potatos and an unknown number of 5-pound bags of pota
Diano4ka-milaya [45]

Answer:

60+5x = 180    

Step-by-step explanation:

Let the number of bags of potatoes be x.

We have been given that a grocery store receives a 180-pound crate containing six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes.

The weight of 6 potato bags of 10 pound each will be 6\times 10=60 pounds.

We can write an equation for the number of bags of potatoes by equating the weight of six 10-pound bags of potatoes and x 5-pound bags of potatoes with 180 pounds.  

6*10+5x = 180

60+5x = 180

Therefore, the equation that represents the number of bags of potatoes in the crate is 60+5x = 180.
