He will need 2/3 of a cup.
You can do this by setting up a proportion, so
(2/3)/(3/4) = x/1.
Then you would get 2/3 = 3/4x
Divide both sides by 3/4
X = 8/9

Use properties of equality to find the value of x in the equation 12(5x-4.5)=36
lukranit [14]

Answer:

x= 1.5 Hope that helps!

Step-by-step explanation:

1. 12(5x-4.5)=36 First Divide both by 12 5x-4.5-36/12 = 3

2. 5x-4.5=3 add 4.5 to both sides

3. 5x= 3+4.5 = 7.5

4. 5x=7.5 divide both sides by 5 x=7.5/5= x=1.5

So, x=1.5 would be your answer. Can you make me Brainliest Please

1. Mrs. Shelley's class is reading The Lion, the Witch,
Andru [333]

Answer:

80 weeks

Step-by-step explanation:

We can use proportions to figure out the answer to this problem:

\frac{16}{1} = \frac{x}{5}

16 pages every week, and some amount of pages every 5 weeks. Notice that if we can multiply 1 by 5 to get 5, we should be able to multiply 16 by 5 to get the value of x. 16 times 5 is 80, and this is the answer to our problem.

Which, if any, of
Nadya [2.5K]

You need to convert the cartesian coordinates to polar: This means we need to go from (x, y) --> (r, angle)

We can covert, using the following formulas:

Find r:

(x, y) --> (2, 2\sqrt{3})

r^2 = \sqrt{x^2 + y^2}

r^2 = \sqrt{2^2 + (2\sqrt{3})^2}

r = 4

Now, find our angle:

Use the inverse of tan

\tan^{-1} \frac{2}{2\sqrt{3}} = 30\deg

Turn 30 degrees to radian

\frac{\pi}{180} * 30 = \frac{1}{6}\pi

Answer = (4, \frac{1}{6}\pi) = C

It's a proportion.
2 is to x as 15 is to 9, or 2/x = 15/9.
Multiply the means and extremes
15x = 18
divide both sides by 15 to get x by itself.
x = 1.2
