Answer:

x = 20

Step-by-step explanation:

Since ΔACB ≅ ΔDCE then ∠A ≅ ∠D, that is

3x - 10 = 2x + 10 ( subtract 2x from both sides )

x - 10 = 10 ( add 10 to both sides )

x = 20

Bernardo is converting a fraction, StartFraction a Over b EndFraction, to a percent. Both a and b are whole numbers and not equa

anyanavicka [17]

Answer:

$Percent = \frac{100a}{b}\%$

Step-by-step explanation:

Given

$\frac{a}{b}$

Required

Convert to fraction

To do this, we simply multiply the fraction by 100%

This gives:

$Percent = \frac{a}{b} * 100\%$

$Percent = \frac{a * 100}{b}\%$

$Percent = \frac{100a}{b}\%$

The expression cannot be further simplified.

Take for instance the fraction is: $\frac{2}{5}$

Using the same analysis, the percentage would be:

$Percent = \frac{2}{5} * 100\%$

$Percent = \frac{2 * 100}{5}\%$

$Percent = \frac{200}{5}\%$

$Percent = 40\%$

Solving special systems<br> {y=1/2x+4<br> {-1/2x+y=-5

ryzh [129]

Answer:

no solution

Step-by-step explanation:

Given the 2 equations

y = $\frac{1}{2}$ x + 4 → (1)

- $\frac{1}{2}$ x + y = - 5 → (2)

Substitute y = $\frac{1}{2}$ x + 4 into (2)

- $\frac{1}{2}$ x + $\frac{1}{2}$ x + 4 = - 5 , that is

4 = - 5 ← not possible

This indicates the system has no solution

Make x the subject of the formula<br> mx=y

Alika [10]

You’re going to have to single out the x. So, the way to go is divide both sides by m. Then you’re left with

x = y/m
