Ur gonna have to pick an equation and solve for a variable.
2x - 2y = 6
2x = 2y + 6 ...divide everything by 2 because u want x by itself
x = y + 3
now we sub y + 3 in for x in the other equation
14x - 2y = 78
14(y + 3) - 2y = 78...distribute thru the parenthesis
14y + 42 - 2y = 78...subtract 42 from both sides, cancelling the 42 on the left
-42 -42
-----------------------
14y - 2y = 36 ...simplify
12y = 36...divide by 12 on both sides, cancelling out the 12 on the left
y = 36/12
y = 3
now , we already know that x = y + 3...and we know y = 3...so sub in 3 for y and solve for x
x = y + 3
x = 3 + 3
x = 6
solution is (6,3)
it is always a good idea to check ur answer by subbing it into one or both of the equations to see if it is correct
2x - 2y = 6......(6,3)...x = 6 and y = 3
2(6) - 2(3) = 6
12 - 6 = 6
6 = 6 (correct)
so yes, ur solution is (6,3)
Answer:
Lowest is 100
Highest is 125
Step-by-step explanation:
We use the 5 number summary to be the foundation of a graphical representation referred to as the box plot. One box would move from one quartile which is the lowest quartile Q1 to the another quartile Q3 which is the upper quartile.
Now if a box plot is to be made given the the information in this question, the box is going to go from Quartile 1 to Quartile 3.
Then the Lowest value would be 100 and the highest 125
Answer:
Step-by-step explanation:
The area of the circumference of a circle is:
We know that r is 8, so we can plug that into the formula.
However, there's a problem. We only want 3pi/4 of the circumference, not the entire circle's circumference. Therefore, we have to divide by part/whole. In this case, the part is 3pi/4, and the whole is 2pi (the entire circle is 2pi radians).
Answer:
<em>The correct answer is </em><u><em>(-B-)</em></u>
Step-by-step explanation:
<em>Why this would be (B), A normal size shape triangle is a right angle and that would mean the L=Length, = </em><u><em>5</em></u><em>, H=Height=</em><u><em>6</em></u><em>, B=Base, = </em><u><em>5</em></u><em>. </em>
You can take 5 and 10 to turn that into 15 and + 6 = 21 x bh = 40
