Can i please get help with these

Kryger [21]

Answer:

7. x=3, 8. x=7, 9. x=15.

Step-by-step explanation:

7. If lines m and n are congruent, then angles DCF and CFE are congruent. 15x+3=18x-6. Solve for x. --> 15x+9=18x-->3x=9-->x=3

8.If line m is parallel to line n, then the corresponding angles are congruent. So, 20x+1=22x-13 Solve for x. 20x+14=22x-->14=2x-->x=7.

9. The supplementary angle of 110 is 70. Note that all of the inner angles of a triangle are equal to 180. Form an equation using the the values: (4x+8)+(2x+12)+70=180. Simplify; 6x+90=180. Solve for x: 6x+90=180-->6x=90-->x=15.

Hope this helps!

Need some help with these problems!

Answer:

Step-by-step explanation:

<u>System of Linear Equations </u>

We have 3 unknown variables and 3 conditions between them. They form a set of 3 equations with 3 variables.

We have the following data, being

w = price of a sweatshirt

t = price of a T-shirt

h = price of a pair of shorts

19.

The first condition states the price of a sweatshirt is twice the price of a pair of shorts. We can write it as

$\displaystyle w=2h$

The second condition states the price of a T-shirt is $4 less than the price of a pair of shorts. We can write it as

$\displaystyle t=h-4$

The final condition states Brad purchased 3 sweatshirts, 2 pairs of shorts, and 5 T-shirts for $136, thus

$\displaystyle 3w+2h+5t=136$

This is the system of equations we need to solve for w,t,h

20.

To solve the system, we replace w in terms of h and t in terms of h. Those relations have been already written, so

$\displaystyle 3(2h)+2h+5(h-4)=136$

Operating

$\displaystyle 6h+2h+5h-20=136$

$\displaystyle 13h=156$

Solving for h

$\displaystyle h=12$

The other two variables are

$\displaystyle w=2h=24$

$\displaystyle t=12-4=8$

What does it mean? I need help with this

kykrilka [37]

In order to do mean you have to add all of the numbers in the list together. then divide them by the total amount of numbers (ex. 7,9,3,2,5. you would add all of these up 7+9+3+2+5=26 then you would divide that by 5 because there are five numbers in the list.
