Lets define a=1st number, b=2nd number, and c=3rd number

We know that a+b+c=126

We also know that the second number is 6 more than the first, so we can represent this as b=a+6

We also know that the third number is 3 times the first which can be represented as c=3a

We can plug these new values into our original equation and get:

a+(a+6)+(3a)=126

2a+6+3a=126 COMBINE LIKE TERMS

5a+6=126

5a=120

a=24

Our first number is 24.

Our second number is 6 more than our first number, so the second number is 24+6=30

Our third number is 3 times the first number, so the third number is 3(24)=72

We can check by plugging these numbers in for a, b, and c in our original equation

a+b+c=126

24+30=72=126

126=126

Which of the following equations is on the same path as x=2-3t, y=7-6t?

Svet_ta [14]

Answer:

C. $y = 3+2\cdot x$

Step-by-step explanation:

Let be the parametric equations $x = 2-3\cdot t$ and $y = 7 - 6\cdot t$ , we need to clear $t$ and eliminate it afterwards to obtain a function of the form $y = f(x)$ :

$x = 2 - 3\cdot t$

$3\cdot t = 2 - x$

$t = \frac{2}{3}-\frac{1}{3}\cdot x$ (1)

$y = 7 - 6\cdot t$

$6\cdot t = 7 - y$

$t = \frac{7}{6} - \frac{1}{6}\cdot y$ (2)

By (1) and (2):

$\frac{2}{3}-\frac{1}{3}\cdot x = \frac{7}{6}-\frac{1}{6}\cdot y$

$4 -2\cdot x = 7 - y$

$y = 3+2\cdot x$

Hence, the correct answer is C.

HURRY !!! PLEASE HELP!!

sesenic [268]

Answer:

2. it stays the same even if the angles in the triangle change

a. the angles must add up to 180º. a straight line is equal to 180º, so as long as the angles add up to 180º, it will be a straight line.

5. it represents the sum of the measures of the interior angles of the triangle

a. Kellianne lined up the interior angles of the triangle. if added they equal 180º which is the measure of the straight line.

7. it combines the three interior angles of the triangle to form a straight line

a. same answers as previous

8. it is a straight line with a measure of 180º

a. refer to above

hope this helps :)
