Answer:
x : -3
Step-by-step explanation:
1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)
2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)
3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)
4) -6x = 18 (divide the -6 on both sides)
5) x = -3
Answer: 6.25
Step-by-step explanation:
Because corresponding sides of similar triangles are proportional,
The measure of angle RQS is 50°.
Solution:
Given data:
m(ar QTS) = 260°
<u>Tangent-chord theorem:</u>
<em>If a tangent and chord intersect at a point, then the measure of each angle formed is half of the measure of its intercepted arc.</em>
m∠PQS = 130°
<em>Sum of the adjacent angles in a straight line is 180°.</em>
m∠PQS + m∠RQS = 180°
130° + m∠RQS = 180°
Subtract 130° from both sides.
130° + m∠RQS - 130° = 180° - 130°
m∠RQS = 50°
The measure of angle RQS is 50°.
Well, estimate means to get like a general idea, or "in the ball park".
The factors include; the trip which is $26, and the ammount of students in the class, which is 22.
In order to estimate, you need to round.
$26 rounded becomes $30.
22 rounded becomes 20.
So now that we have the rounded numbers, we solve the problem. In order to find the total cost for all the students, we multiply the amount of students, by the ammount of money it costs per student.
The estimated version of this is: 20x30=600
This means that the estimated answer is $600 total.
Now do the same thing with the actual numbers.
22x26=572.
This means that the actual answer is $572.
The roumded total
Answer is $600.
You can say it is better use the actual numbers, and not estimate, because it is the actual answer.
I hope this helps you, im sorry for the long answer :)
