Answer:
1.) x = 110

So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110

2.) x = 72

For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72

3.) c = 24

For 5 to become 40 it must be multiplied by 8 because 5 × 8 = 40. I have to multiply 8 by the numerator as well and 3 × 8 = 24. c = 24

Answer:

Step-by-step explanation:
In the figure you can identify up to 3 straight triangles.
To solve the problem, write the Pythagorean theorem for each triangle.
<em>Triangle 1</em>

<em>Triangle 2</em>

<em>Triangle 3</em>

Now substitute equation 2 and equation 3 in equation 1 and solve for y.






substitute the value of y in the second equation and solve for z





Answer:
180°
Step-by-step explanation:
Answer:
y = 1/3x + 4
Step-by-step explanation:
The slope intercept form is y=mx+b so what we need to do is fill in the blanks. M is the slope and we know the 1/3 is the slope. (0,4) is basically meaning that the x-value is 0 and the y-value is 4, and when that's the case it means 4 is the y-intercept. Now we can put the information together y = 1/3x +4 is the equation.
Hope this helps and have a great day!
