You must have been taught postulates and theorems that allow you to prove triangles congruent, such as SSS, SAS, ASA, etc. Look at the given information of a proof, and see how from the given information, using definitions, postulates, and theorems you have already learned, you can show pairs of corresponding sides and angles to be congruent that will fit into the above methods. Then use one of the methods to prove the triangles congruent.
The amount of pens he buys affects the amount he spends. (not vice versa)
independant = amt. of pens
dependant = amt. spent
Sofia would bike 65 miles a day
and to figure this out you need to divide 325 by 5
325/5=5
Answer:
i have this question too and i cant figure it out.
Step-by-step explanation:
Answer:
4.)
a. x= <u>-6</u> y-3
5
b. x= <u>5</u> y + <u>13</u>
4 4
3.)
a. x= <u>-4y</u> + <u>-8</u>
5 5
b. x=<u> 3</u> y+3

Step-by-step explanation:
4.)
a. 5x+6y=-15
Add -6y to both sides.
5x+6y+−6y=−15+−6y
5x=−6y−15
Divide both sides by 5.
5x ÷ 5= -6y-15 ÷5
x= <u>-6</u> y-3
5
b. 4x - 5y=13
Add 5y to both sides
4x−5y+5y=13+5y
4x=5y+13
Divide both sides by 4
4x÷4= 5y+13÷4
x= <u>5</u> y + <u>13</u>
4 4
5.)
a. (5x+4y=-8)
Add -4y to both sides
5x+4y+−4y=−8+−4y
5x=−4y−8
Divide both sides by 5
5x÷5= -4y-8÷5
x= <u>-4y</u> + <u>-8</u>
5 5
b. 2x - 3y = 6
Add 3y to both sides.
2x−3y+3y=6+3y
2x=3y+6
Divide both sides by 2.
2x÷2= 3y+6÷2
x=<u> 3y</u>+3
