To solve this problem, we are going to use the percent proportion, a/b = p/100, where a is the part of a number b, the whole, and p is the percentage out of 100.
When we fill in our known integers into this equation, we get
21.12 / b = 25.6 / 100
Next, to simplify this equation, we should use cross products (means - extremes products theorem). This means multiplying the numerator of one fraction and the denominator of the other fraction and setting them equal to one another.
21.12(100)=25.6(b)
When we multiply, you get
2112 = 25.6b
Finally, we divide both sides by 25.6, to get our variable b, alone, and without a coefficient.
82.5 = b
Therefore, 25.6% of the number 82.5 is 21.12.
Answer:
17.5
Step-by-step explanation:
formula:
y=k(x)
direct variation^^^
y=7, x=2
substitute it in the formula
7=(k)2 or 7=2k
7/2 or 3.5= k, k is the constant
now substitute k to the problem
y=5k
y=5(3.5)
y=17.5
The value of x is 1.
* Let's explain how to solve the problem
- Line PU has points R and S between points P and U
- Line QR intersects line PU at point R
- Line ST intersects line PU at point S
- Lines QR and ST are parallel
- Look to the attached figure
∵ QR // ST
∴ m∠TSU = m∠QRU ⇒ corresponding angles
∵ m∠TSU = 15(x + 2)°
∴ m∠QRU = 15(x + 2)
∵ Points P, R, S lie on the same line
∵ RQ intersects PS at R
∵ m∠PRQ + m∠QRU = 180° ⇒ straight angle
∵ m∠PRQ = 135°
∵ m∠QRU = 15(x + 2)°
∴ 135 + 15(x + 2) = 180
∴ 135 + 15x + 30 = 180
- Add like terms
∴ 15x + 165 = 180
- Subtract 165 from both sides
∴ 15x = 15
- Divide both sides by 15
∴ x = 1
∴ The value of x is 1
In geometry, parallel lines are coplanar instantly traces that do not intersect at any factor. Parallel planes are planes in identical three-dimensional space that in no way meet. Parallel curves are curves that do not touch every different or intersect and hold a set minimal distance
In mathematics, the intersection of or more gadgets is any other item that includes the whole thing that is contained in all the items simultaneously.

Answer:
Its B since the decimals are lower than the data.
Between Steps 1 and 2, the student added 6x to the left hand side, but subtracted 6x from the right hand side.
