2/9w = 24
Ludmilka [50]

Step-by-step explanation:

2/9w=24

cross multiply

2w=216

w=216/2

w=108

8/9p=12/18

cross multiply

144p=108

p=108/144

p=0.75

2.5c=15.75

c=2.5/15.75

c= 0.16

cross multiply

390n=-390

n=-390/390

n= -1

Using the completing-the-square method, rewrite f(x) = x2 − 6x + 2 in vertex form.
Irina18 [472]

Answer:

f(x)=(x-3)^2-7

Step-by-step explanation:

Vertex form: f(x) = a(x-h)^2+k

x^2-6x+9+2=f(x)+9

(x-3)^2+2=f(x)+9

f(x)=(x-3)^2-7

The measures of two supplementary angles have a ratio of 4:5. What is the measure of the larger angle?
vladimir1956 [14]

Answer:

100 is larger, that is your answer.

Step-by-step explanation:

First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x. Since 100 is larger, that is your answer.

I hope this helps.
