Answer:
15 grams
Step-by-step explanation:
30% of 50 grams are cocoa.
Convert the % to a decimal and multiply by 50 grams.
(0.30)*(50 g) = 15 grams
The two numbers are 4.95 and 2.25.
<h3>
Explanation: </h3>
Let the two numbers be x and y. Given conditions,
...............................(1)
................................(2)
Adding equations (1) and (2), we get
![LHS = x+y+x-y = (2x - y+y) = 2x\\RHS=7.2+2.7 = 9.9](https://tex.z-dn.net/?f=LHS%20%3D%20x%2By%2Bx-y%20%3D%20%282x%20-%20y%2By%29%20%3D%202x%5C%5CRHS%3D7.2%2B2.7%20%3D%209.9)
Therefore ![2x = 9.9; x=9.9/2 = 4.95](https://tex.z-dn.net/?f=2x%20%3D%209.9%3B%20x%3D9.9%2F2%20%3D%204.95)
x=4.95 .......................(3)
Substituting value of x from (3) in (1), we get
![x+y = 7.2\\4.95+y=7.2\\y=7.2-4.95 = 2.25](https://tex.z-dn.net/?f=x%2By%20%3D%207.2%5C%5C4.95%2By%3D7.2%5C%5Cy%3D7.2-4.95%20%3D%202.25)
y=2.25 ........................(4)
From (3) and (4), the two numbers are 4.95 and 2.25.
Answer:
46656
Step-by-step explanation:
6*6*6*6*6*6*6 = 6x
Multiply the terms.
279936 = 6x
Divide 6 into both sides.
279936/6 = 6x/6
= 46656
The circumference would be 6 inches because you do 3 times 2
Answer:
x = 7
Step-by-step explanation:
Because the points are collinear:
AB + BC = AC
We'll plug in the expressions in terms of x.
(-1 + 2x) + (11) = (3x + 3)
And solve for x. Combine like terms on the left
2x + 10 = 3x + 3
Subtract 3 on both sides
2x + 7 = 3x
Subtract 2x on both sides
7 = x
