First you multiply both equations by 2 from the 1/2x
Then, you get 10x+10=x-8
Next you move the x to the left side from the right
Now you subtract 10 by both sides which is: 10x-x=-8-10
Collect like terms; 9x=-18
Lastly, you divide 9 by both sides and you get
x=-2

ΔMNO is shown.
JulijaS [17]

Answer:

ABC - AAS

DEF - not enough information

GHI - not enough information

JKL - SAS

Step-by-step explanation:

SAS postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

AAS postulate states that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.

HL postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.

ASA postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

SSS postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

1. In triangles MNO and ABC, there are two congruent sides and non-included angle - AAS

2. In triangles MNO and DEF, there are two congruent sides  - there is not enough information

3. In triangles MNO and GHI, there are three congruent angles  - there is not enough information

4. In triangles MNO and JKL, there are two congruent sides and included angle - SAS

Brooke and Lamont ran a half marathon. Brooke finished in 1 hour 40
Paha777 [63]

Answer:

B. Brook finished in 100 minutes, so Lamont was faster.

Step-by-step explanation:

1 hour = 60 Minutes

60 minutes + 40 minutes = 100 Minutes.

If you run and you have more minutes then someone else that means you ran for a longer time and your a little bit slower?
