Write a equivalent expression for 4(a+5) by modeling

anastassius [24]

Answer:

The answer is 4a+20....

Step-by-step explanation:

Use the distributive property.

According to which when using the distributive property, you have to distribute (multiply) the 4 to the a and then the 4 to the 5. It looks like this.

4(a+5)

4(a)= 4a

4(5)=20

Thus the expression becomes:

4a+20

Thus the answer is 4a+20....

Which expression would be equivalent to: Which expression would be equivalent to: \frac{1+b}{2} - 3(a-1)

IrinaVladis [17]

Answer:

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Step-by-step explanation:

Given

$\frac{1+b}{2} - 3(a-1)$

Required

An equivalent expression

$\frac{1+b}{2} - 3(a-1)$

Take LCM

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 2*3(a-1)}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6(a-1)}{2}$

Open bracket

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6a+6}{2}$

Collect like terms

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+6+1}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Hence, an equivalent expression is:

$\frac{b- 6a+7}{2}$

What is 3/x+2 = 4/x+1<br> So what is 'x'

spin [16.1K]

$\frac{3}{x+2} = \frac{4}{x+1} \\ \\ 3(x + 1) = 4(x + 2) \\ \\ 3x + = 4x + 8 \\ \\ 3 = 4x + 8 - 3x \\ \\ 3 = x + 8 \\ \\ 3 - 8 = x \\ \\ -5 = x \\ \\ x = -5 \\ \\$

The final result is: x = -5.
