So what you do for distributive property is take #1 for example: 3(2x + 10) = 54. When there’s a parenthesis, you take the outside number which is the 3 times the numbers inside the parenthesis. So after doing that first step you should get 6x + 30 = 54. Now you want to get rid of the 30 so you do 30-30=0 but you have to do it on the other side as well. So subtracting 30 on both sides you should have 6x = 24. Now you want to get x by itself. The opposite of multiplying is dividing so you divide 6 from 6x. So the same on the other side. You get your answer x=4 if you did everything correct

Variables:
p = uniform pants
c = baseball caps

Equations:
$2p + 2c = 68$
$p - c = 12$
****************************************************************************************
Step 1.
$\left {{2p+2c=68} \atop {p-c=12}} \right$

Step 2.
$\left {{2p+2c=68} \atop {2(p-c=12)}} \right.$

Step 3.
$\left {{2p+2c=68} \atop {2p-2c=24}} \right.$

Step 4.
$4p = 92$

Step 5.
$\frac{4p}{4} = \frac{92}{4}$
$p=23$

Step 6.
$p-c=12$
$23 - c=12$
 $23=12+c$
 $11=c$

Baseball Pants = $23
Baseball Caps = $11

For a certain race, 3 teams were allowed to enter 3 members each. A team earned 6 – n points whenever one of its members finishe

ololo11 [35]

Answer:

The least possible score a team could have earned is 3.

Step-by-step explanation:

From the given information it is clear that the total number of teams is 3.

Total number of members in each team is 3.

A team earned 6 – n points whenever one of its members finished in nth place, where 1 ≤ n ≤ 5.

It means the points for 1st, 2nd, 3rd, 4th, and 5th place are 5, 4, 3, 2 and 1 respectively.

Total points that can be earned all teams together = 5+4+3+2+1=15

There were no ties, disqualifications, or withdrawals.

To minimize the score of a team, we have to maximize the score of the other two teams.

It is given that no team earned more than 6 points,

Let two teams earn there maximum score. i.e. 6. So the score of third team is

$15-6-6=3$

Therefore, the least possible score a team could have earned is 3.

Answer:

ΔMVL ~ ΔTVU by SAS

Step-by-step explanation:

Lets verify the ratio of corresponding sides:

8/28 = 2/7
14/49 = 2/7

Two sides are similar and the included angles are congruent as vertical angles:

LV/UV = MV/TV
∠MVL ≅ ∠TVU
ΔMVL ~ ΔTVU by SAS
