Answer:

Solution given

5(1+s)=9s+6

distribute

5+5s=9s+6

subtract both side by 5s

5+5s-5s=9s-5s+6

solve like terms

5=4s+6

subtract both side by 6

5-6=4s+6-6

-1=4s

divide both side by 4

-1/4=s

Answer:

[tex]s=-\frac{1}{4}[/tex]

[tex]s=-0.25[/tex]

Step-by-step explanation:

[tex]5\left(1+s\right)=9s+6[/tex]

Apply distributive law:-

[tex]5\left(1+s\right)[/tex]

[tex]=5+5s[/tex]

[tex]5+5s=9s+6[/tex]

Now, Subtract 5 from both sides :-

[tex]5+5s-5=9s+6-5[/tex]

[tex]5s=9s+1[/tex]

Subtract 9s from both sides:-

[tex]5s-9s=9s+1-9s[/tex]

[tex]-4s=1[/tex]

Divide both sides by -4:-

[tex]\frac{-4s}{-4}=\frac{1}{-4}[/tex]

[tex]s=-\frac{1}{4}[/tex]

Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100.

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42? … I hope it helps you

Answer:

7 and 34

Step-by-step explanation:

let x and y be the 2 numbers with x > y

The 2 equations to solve are

x = 4y + 6 → (1)

x + y = 41 → (2)

Substitute x = 4y + 6 into (2)

4y + 6 + y = 41 , that is

5y + 6 = 41 ( subtract 6 from both sides )

5y = 35 ( divide both sides by 5 )

y = 7

Substitute y = 7 into (1)

x = 4(7) + 6 = 28 + 6 = 34

The 2 numbers are 7 and 34

Find the decimal for 2 out of 5 by dividing 2 by 5:

2 out of 5 = 2/5 = 0.40

Multiply total people by 0.40:

Answer: 1,000

Answer:

-2/5 =x

Step-by-step explanation:

2/3 ( x-2) = 4x

Multiply each side by 3/2

3/2 * 2/3 (x-2) = 3/2 *4x

x-2 = 6x

Subtract x from each side

x-2-x = 6x-x

-2 = 5x

Divide each side by 5

-2/5 = 5x/5

-2/5 =x

x=−  2/5=−0.4 is the answer please mark brainliest

Answer:

Solution given:

7+4c=7c+6

subtracting both side by 4c

7+4c-4c=7c-4c+6

solve like terms

7=3c+6

subtracting both side by 6

7-6=3c+6-6

3c=1

c=1/3

Answer:

c = -1/3

Step-by-step explanation:

7 + 4c = 7c + 6

7 - 8 + 4c = 7c

-1 + 4c = 7c

-1 = 7c - 4c

-1 = 3c

Answer:

If you don't have a protractor handy, you can determine the size of an angle using the basic geometric principles of triangles. You'll need a scientific calculator to solve the equations. Most smartphones are equipped with them, but you can also download a free app or access a free calculator online.

Estimation and precision are used when the actual value cannot be easily determined or calculated.

Given that, the length is to be measured to the nearest [tex]\frac 14\ inch[/tex], we have the following observations

So, we have:

[tex]L_1 = 2\frac 14[/tex] --- the length of the abdomen

[tex]L_2 = 4 - 2\frac 14[/tex]

Express as improper fraction

[tex]L_2 = 4 - \frac{9}{4}[/tex]

Take LCM

[tex]L_2 = \frac{16 - 9}{4}[/tex]

[tex]L_2 = \frac{7}{4}[/tex]

Express as proper fraction

[tex]L_2 = 1\frac{3}{4}[/tex] --- the length of the thorax

The number of times (n) the abdomen is longer than the thorax is calculated as follows:

[tex]n = L_1 \div L_2[/tex]

So, we have:

[tex]n = 2\frac 14 \div 1\frac 34[/tex]

Express as improper fractions

[tex]n = \frac 94 \div \frac 74[/tex]

Rewrite as:

[tex]n = \frac 94 \times \frac 47[/tex]

[tex]n = \frac 97[/tex]

Express as proper fractions

[tex]n = 1\frac 27[/tex]

Hence, the abdomen is [tex]1\frac 27[/tex] times longer than the thorax

Answer: 2.3/225.4=0.01020408

Answer:

98.000

Step-by-step explanation:

Change the divisor 2.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

2254 ÷ 23 = 98.000

and therefore:

225.4 ÷ 2.3 = 98.000

Both calculated to 3 decimal places.

Answer:

About 113.

Step-by-step explanation:

45 + 0.05t +0.58v = 55.29

v = 8

t is 113 text messages.

Kristy’s sent About 113 text messages..

An equation represents equality of two or more mathematical expression.

When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

It is given that Kristy’s cellphone company charges a monthly rate of $45 plus $0.05 per text message sent and $0.58 per video messages sent.

Also Kristy’s sent 8 video messages in October and receive a bill for $55.29.

The equation form as;

45 + 0.05t +0.58v = 55.29

Solve for t when v = 8;

45 + 0.05t +0.58(8) = 55.29

t = 113

Therefore, she sent 113 text messages.

Answer:

b = 15

Step-by-step explanation:

2 (b - 8) + -11 = 3

2b - 16 + -11 = 3

2b - 16 + -11 = 3

2b - 27 = 3

2b = 3 + 27

2b = 30

b = 30 ÷ 2

b = 15

Answer:

[tex] = > 2(b - 8) + - 11 = 3[/tex]

[tex] = > 2b - 16 + - 11 = 3[/tex]

[tex] = > 2b - 27= 3[/tex]

Answer:

a= 3/11

b = 2/11

Step-by-step explanation:

a(1) + b(4) = 1

a + 4b = 1

a(3) + b(1) = 1

3a + b = 1

b = 1-3a

a + 4(1-3a) = 1

a+ 4-12a = 1

-11a = -3

a = 3/11

b = 1-3(3/11)

b= 2/11

The value of a and b are 3/11 and 2/11 respectively.

An equation is an expression that shows the relationship between two or more numbers and variables.

We have been given that the straight line ax+by=1 passes through the points (1,4)and (3,1).

Thus, the equation of the straight line passing through the point ( 3,1 )

a(3) + b(1) = 1

3a + b = 1

b = 1-3a

Thus, the equation of the straight line passing through the point(1,4)

a(1) + b(4) = 1

a + 4b = 1

Now substitute the value of b;

a + 4(1-3a) = 1

a+ 4-12a = 1

-11a = -3

a = 3/11

Then b = 1-3(3/11)

b= 2/11

Hence, the value of a and b are 3/11 and 2/11 respectively.
