5x-4[7+(2x-4)], for x=-3

Answer:

b= x

Step-by-step explanation:

[tex]\boxed{ {x}^{m} \times {x}^{n} = {x}^{m + n} }[/tex]

Applying the law of indices above:

[tex]b = {x}^{ \frac{1}{4} } \times {x}^{ \frac{3}{4} } [/tex]

[tex]b = {x}^{ \frac{1}{4} + \frac{3}{4} } [/tex]

[tex]b = {x}^{ \frac{4}{4} } [/tex]

[tex]b = {x}^{1} [/tex]

∴b= x

Answer:

It is b = x

Step-by-step explanation:

From law of indices:

[tex] {a}^{b} \times {a}^{c} = {a}^{(b + c)} [/tex]

for, multiplication: same coefficients, we sum up the powers.

[tex]b = {x}^{ \frac{1}{4} } \times {x}^{ \frac{3}{4} } \\ b = {x}^{( \frac{1}{4} + \frac{3}{4} ) } \\ b = {x}^{ \frac{4}{4} } \\ b = {x}^{1} \\ b = x[/tex]

The simplified form of the expression is 2(31x-20).

Given the expression is -2(x-4)-8(6-8x).

Expressions in mathematics are mathematical statements containing at least two terms containing numbers or variables or both connected by an intermediate operator.

The given expression is solved by using the distributive property a(b+c)=ab+bc, we get

-2(x-4)-8(6-8x)=-2x-4(-2)-8(6)-8(-8x)

-2(x-4)-8(6-8x)=-2x+8-48+64x

Now, we will simplify the above expression by adding or subtracting like terms, we get

-2(x-4)-8(6-8x)=62x-40

-2(x-4)-8(6-8x)=2(31x-20)

Hence, the simplified form of the given expression -2(x-4)-8(6-8x) is 2(31x-20).

Answer:

He paid $9 twelve times

12× 2= 24 days

Step-by-step explanation:

1st day = $16.60

3rd day=$ 9 (i.e for every 2days afterwards)

5th day=$ 9

Yuri pays : 124.60

124.60-16.60

= $108.00

After paying the first day he paid 108.00

108.00÷ 9 = 12

He paid $9 twelve times

Hi! I'm happy to help!

To solve this, we need to divide the amount of money by the number of hours.

You earned $42.25, over the course of 6.5 hours.

42.25/6.5

6.5

So, you earned $6.50 per hour cleaning a community park.

I’m sorry about that. I never would have imagined myself choosing those two over you.

Answer:

2/3

Step-by-step explanation:

1/6 + 3/6 = 4/6

4/6 = 2/3

Step-by-step explanation:

if I understand the typed information here, we have

(-4 + 8x) + 3 > -4

so, I am looking at that :

-4 + 8x + 3 > -4

let's first add 4 on both sides

8x + 3 > 0

then subtract -3 on both sides

8x > -3

and finally divide both sides by 8

x > -3/8

since we never multiplied or divided by a negative number, the inequality sign stays the same.

so, this inequality is true for all x > -3/8

Answer:

B (Base surface area) = 16 [tex]m^{2}[/tex]

P (Perimeter of the base) = 16 m

H (Height) = 6 m

L (Not sure what L means. I assume it's the slant height??) =  6.32 m

LA (I assume lateral surface area) = [tex]50.59 m^{2}[/tex]

SA (I assume total surface area) = [tex]66.59 m^{2}[/tex]

V (volume) = [tex]32 m^{3}[/tex]

Step-by-step explanation:

Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.

Perimeter of base=4(4)=16m

Area of base=4²=16m²

Height=6m

Slant height=6.3m

Lateral surface area=4(1/2(4)(6.3))=8(6.3)=50.54m²

Total surface area=50.54+16=66.54m²

Volume=a²h/3=4²/(6)/3=16(2)=32m³

From left to right (least to greatest): 0.052, 0.27, 0.52, 0.65, 0.8

13.54 g/mL = (100 g)/v

==>   v = (100 g)/(13.54 g/mL) = 7.39 mL

The volume of 100 grams of mercury is 7.38 mL when the density of mercury is 13.54 g/mL.

To calculate the volume of 100 grams of mercury, we can use the density formula:

Density = Mass / Volume

We are given the density of mercury as 13.54 g/mL, and we want to find the volume in mL.

Volume = Mass / Density

Substituting the given values:

Volume = 100 g / 13.54 g/mL

Simplifying the division:

Volume= 7.38 mL

Therefore, the volume of 100 grams of mercury is 7.38 mL.

Answer:

The numbers are 8, 24 and 30

Step-by-step explanation:

Let x be the first number.

If the second number is triple the first, then the second number is 3x

If the third number is the second number plus six, then the third number is 3x + 6

So therefore the equation is:

[tex]x + 3x + (3x + 6) = 62[/tex]

Solving for x,

[tex]x + 3x + 3x + 6 = 62\\7x = -6 + 62\\7x = 56\\x = 8[/tex]

But why is the second number 24?

[tex]3x = 24\\3(8) = 24\\24 = 24[/tex]

And why is the third number 30?

[tex]3x + 6 = 30\\24 + 6 = 30\\30 = 30[/tex]
