Answer:

n=-1

Step-by-step explanation:

3n-5=-8(6+5n)

3n-5=-48-40n

add 40n to both sides

43n-5=-48

n=-1

Using distributive property we can expand the expression as

3n - 5 = -8 x 6 + (-8) x 5n

To apply the distributive property to the equation

3n - 5 = -8(6 + 5n), we need to distribute the -8 to the terms inside the parentheses.

Using the distributive property, we have:

3n - 5 = -8 x 6 + (-8) x 5n

Simplifying further:

3n - 5 = -48 - 40n

Now, we can continue solving the equation using the simplified form as

3n + 40n = -48 + 5

43n = -43

n= -1.

Question (3)

The given expression is,

[tex]\frac{4(x-3)}{3}=20[/tex]

       Statements                Proof

1). [tex]\frac{4(x-3)}{3}=20[/tex]                1). Given

2). [tex]4(x-3)=60[/tex]           2). Multiplication property of equality

3). 4x - 12 = 60             3). Distributive property

4). 4x = 72                    4). Addition property of equality

5). x = 18                       5). Division property of equality

Question (4)

Equations are,

5x + 10 = 30 ------(1)

5(x + 10) = 30 ------(2)

From equation (1),

5x + 10 = 30

5x = 30 - 10

x = 4

From equation (2),

5(x + 10) = 30

(x + 10) = 6

x = 6 - 10

x = -4

Therefore, solutions of both the equations are different.

Steps to solve:

m + 55 + 1 = m

m + 56 = m

~Subtract m to both sides

56 = 0

No solution

Best of Luck!

Answer:

no solution

In-depth explanation:

Hi there, let's solve this equation.

For now, I will focus on the left side & combine the like terms:

[tex]\tt{m+55+1=m}[/tex]

[tex]\tt{m+56=m}[/tex]

Subtract 56 from each side:

[tex]\tt{m=m-56}[/tex]

Subtract m from each side:

[tex]\tt{m-m=-56}[/tex]

[tex]\tt{0=-56}[/tex]

Therefore, the equation has no solution.

Answer: A

Step-by-step explanation:

The formula for mass , m= ρ* V

Density, mass of a unit volume of a material substance.

The formula for density is d = M/V, where d is density, M is mass, and V is volume.

Given:

ρ = m/V

where

ρ = density, m = mass, and V = volume.

So, for solving for m we have

m= ρ* V

Hence,  formula for mass , m= ρ* V.

The graph of the equation is y = -3x + 6 and is plotted

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = -3x + 6

where the slope of the line is m = -3

Now , The line crosses the y-axis at 6:

True. To find the y-intercept, we set x = 0 and solve for y: y = -3(0) + 6. This gives y = 6. Therefore, the line crosses the y-axis at y = 6.

As the input increases, the output decreases:

True. Since the coefficient of x is negative, as x increases, the output y decreases.

Hence , the equation of line is solved

Answer:

x = 35

Step-by-step explanation:

Solve for x:

6 x - 15 = 4 x + 55

Hint: | Move terms with x to the left hand side.

Subtract 4 x from both sides:

(6 x - 4 x) - 15 = (4 x - 4 x) + 55

Hint: | Combine like terms in 6 x - 4 x.

6 x - 4 x = 2 x:

2 x - 15 = (4 x - 4 x) + 55

Hint: | Look for the difference of two identical terms.

4 x - 4 x = 0:

2 x - 15 = 55

Hint: | Isolate terms with x to the left hand side.

Add 15 to both sides:

2 x + (15 - 15) = 15 + 55

Hint: | Look for the difference of two identical terms.

15 - 15 = 0:

2 x = 55 + 15

Hint: | Evaluate 55 + 15.

55 + 15 = 70:

2 x = 70

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 70 by 2:

(2 x)/2 = 70/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

x = 70/2

Hint: | Reduce 70/2 to lowest terms. Start by finding the GCD of 70 and 2.

The gcd of 70 and 2 is 2, so 70/2 = (2×35)/(2×1) = 2/2×35 = 35:

Answer:

235=30x-25

Step-by-step explanation:

235+25=30x-25+25

260=30x

260/30=30x/30

x=8.66 or 9 weeks

The equation is 30x + 25 = 235. And the number of weeks will be 7.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

Greg is saving to purchase a tablet that costs $235. He as of now has $25 set aside. Every week, Greg procures $15 looking after children and $25 as a clerk, however, he burns through $10 on snacks.

Let x be the number of weeks. Then the equation is given as,

25x + 15x - 10x + 25 = 235

Simplify the equation, then the number of weeks is given as,

25x + 15x - 10x + 25 = 235

30x = 235 - 25

30x = 210

x = 210 / 30

x = 7 weeks

The equation is 30x + 25 = 235. And the number of weeks will be 7.

Step-by-step explanation:

33/55=0.6

=> 0.31<0.32<0.6

The series converges, since |8/9| = 8/9 < 1.

Let [tex]S_n[/tex] denote the n-th partial sum of the series,

[tex]S_n=\displaystyle\sum_{k=0}^n\left(\frac89\right)^k[/tex]

[tex]S_n=1+\dfrac89+\left(\dfrac89\right)^2+\cdots+\left(\dfrac89\right)^n[/tex]

Multiply both sides by 8/9:

[tex]\dfrac89S_n=\dfrac89+\left(\dfrac89\right)^2+\left(\dfrac89\right)^3+\cdots+\left(\dfrac89\right)^{n+1}[/tex]

Subtract this from [tex]S_n[/tex] to eliminate all but the first term in

[tex]S_n-\dfrac89S_n=1-\left(\dfrac89\right)^{n+1}[/tex]

Solve for [tex]S_n[/tex]:

[tex]\dfrac19S_n=1-\left(\dfrac89\right)^{n+1}[/tex]

[tex]S_n=9-9\left(\dfrac89\right)^{n+1}[/tex]

As [tex]n\to\infty[/tex], the exponential term vanishes, so that

Step-by-step explanation:

Given, Jamie needs to ship 48 plates and 54 bowls to a store.

If she wants to ship the same number of items in each box such that plates and bowls are shipped separately. .

then the  greatest number of items she can ship in each box = GCD (48,54)

[GCD = Greatest common divisor]

Prime factorization of both numbers:

48 =  2 x 2 x 2 x 2 x 3

54 = 2 x 3 x 3 x 3

GCD (48,54)= 2 x 3 = 6

Hence, the greatest number of items she can ship in each box =6

Answer:6

So here's the problem writen down.

48 =  2 x 2 x 2 x 2 x 3

54 = 2 x 3 x 3 x 3

GCD (48,54)= 2 x 3 = 6
