Answer: 7 3/4 - 2/25 = 767/100 = 7 67/100 = 7.67

Step-by-step explanation:

Conversion a mixed number 7 3/4

to a improper fraction: 7 3/4 = 7 3/4 = 7 · 4 + 3/4= 28 + 3/4 = 31/4

To find a new numerator:

a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4/4 = 28/4

b) Add the answer from previous step 28 to the numerator 3. New numerator is 28 + 3 = 31

c) Write a previous answer (new numerator 31) over the denominator 4.

Seven and three quarters is thirty-one quarters

Subtract: 31/4 - 2/25= 31 · 25/4 · 25 - 2 · 4/25 · 4 = 775/100 - 8/100 = 775 - 8/

100 = 767/100

Identify the property used in the first four steps to solve the equation 4(x-7)=2x-6 4x-28=2x-6 2x-28=-6 2x=22 x=11 the answer c

Answer:

The reason of each steps are Distributive property, addition property of equality, addition property of equality and multiplication property of equality.

Step-by-step explanation:

Let a,b and c are real number.

According to distributive property

$a\cdot (b+c)=a\cdot b+a\cdot c$

Where, a,b and c are real number.

According to addition property of equality $a=b$ and $a+c=b+c$ are equivalent equations.

According to multiplicative property of equality $a=b$ and $ac=bc$ are equivalent equations.

The given equation is

$4(x-7)=2x-6$

$4(x)+4(-7)=2x-6$

$4x-28=2x-6$ (Distributive Property)

Add -2x both sides.

$4x-28-2x=2x-6-2x$

$2x-28=-6$ (Addition property of equality)

Add 28 both sides.

$2x-28+28=-6+28$

$2x=22$ (Addition property of equality)

Multiply both sides by $\frac{1}{2}$

$2x\times \frac{1}{2}=22\times \frac{1}{2}$

$x=11$ (Multiplication property of equality)
