Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.

Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.

So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)

If you need help solving or have any questions let me know!

Answer:

2 $\sqrt{3}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$ , then

$\sqrt{12}$

= $\sqrt{4(3)}$

= $\sqrt{4}$ × $\sqrt{3}$

= 2 $\sqrt{3}$

bobbie wrote y+6=15. than she wrote (y+6) divided by 3=15. Explain why the second equation is not equivalent to the first. what

irina1246 [14]

If y+6=15, then y=9. (9+6)divided by 3 would be 5, not 15.

12. Fancy goldfish x cost $3 each and

o-na [289]

Answer:

x (Fancy Gold fish) = 3

y (Common goldfish) = 29

Step-by-step explanation:

Fancy goldfish x cost $3 each

common goldfish y cost $1 each

Graph: y = 20 + 3x (I'm hoping this is the correct line equation, please do leave a comment below if it's not)

Thus, we graph it by subtitude either the x or y values. (Or you can use just X = 1,2,3).

Now, to find how many of each type of goldfish Tasha can buy. We subtitude the line equation by either using x = 3 or y = 1

Using either values to solve the equation, we get:

x = 3

y = 29

Hope this helps!

Solve for x. And graph 7(3x+4)+2<156

blsea [12.9K]

$7(3 \times x + 4) + 2 < 156 \\ 21 \times x + 28 + 2 < 156 \\ 21 \times x + 30 < 156 \\ 21 \times x < 156 - 30 \\ 21 \times x < 126 \\ x < \frac{126}{21} \\ x < 6$

A weather balloon is descending from the atmosphere. Its altitude changes by

OlgaM077 [116]

The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:

Amount of time x change per second = total change
135 x (-6) = X
-810 = X

Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
