x3+x2-6x

The answer should be 10p - 4.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given expression is,

3p + 5 + 7p - 9

To solve this taking alike terms together.

3p + 7p + 5 - 9

Thus, we have

Variables = 3p + 7p = 10p

Constants =  5 - 9 = -4

Thus, the expression becomes,

3p + 5 + 7p - 9 = 10p - 4

So, this is the required answer of the given expression.

Thus, the answer should be 10p - 4.

the second one is 4 x 10^7

subtract the two numbers in each question

convert to scientific notation:

if the number is 40,000,000 the scientific notation would be 4 x 10^7 because there are 7 spaces behind the first digit, or the 4

Answer:

a: given

b: multiplication property of equality

c: distributive property

d: simplified

e: addition property of equality

f. division property of equality

Step-by-step explanation:

step a will always be given because it is starting equation. step b is multiplication property because everything is multiplied by two so you don't have to deal with decimals. step c is distributive because you distribute the -5s in the parentheses. step d is simplified because they combined like terms and nothing changed sides. step e is addition property because you added 5x to both sides. step f is division property because -7 is divided from each side.

Step-by-step explanation:

Area of the border = Length * Breadth

If the outside measures 10in by 11in with 1-in border, the length of the picture with border = 10+(1+1) * 11+(1+1)

Area of the border = 12*13

Area of the border = 156in²

Note that the border length will be added at both edges of the frames for each length and the width of the frame

Step-by-step explanation:

Answer:

Tommy's band won 5 awards, Ali's band won 8 awards and Jack's band won 10 awards.

Step-by-step explanation:

Let the number of awards Tommy won be x.

Number of awards Ali won -> x+3

Number of awards Jack won -> 2x

[tex]x+x+3+2x=23[/tex]

[tex]4x+3=23[/tex]

Subtract 3 from both sides:

[tex]4x+3-3=23-3[/tex]

[tex]4x=20[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{20}{4}[/tex]

[tex]x=5[/tex] (Tommy)

[tex]5+3=8[/tex] (Ali)

[tex]5\times2=10[/tex] (Jack)

Answer: Tommy won 5 awards. Ali won 8 awards. Jack won 10 awards.

Step-by-step explanation:

First give each person a variable:

Tommy = y

Ali = a

Jack = x

Then figure out the equations:

Tommy won 3 less awards than Ali, so the equation would be (y = a - 3).

Jack won twice as many awards as Tommy, so the equation would be (x = 2y)

All three won a total of 23, so that would be (23 = y + x + a)

Next, plug in (2y) into the (x) of (23 = y + x + a)

This would result in (23 = 3y + a)

Then you would plug in (a - 3) into (y)

This would result in (23 = 4a - 9)

Solve for a: (a = 8)

Now that you know (a = 8), plug that into the first equation (y = a - 3) to find (y).

Answer: (y = 5)

Use (y = 5) and plug it into the second equation (x = 2y) to find (x)

Answer: (x = 10)

Answers:

a = 8

y = 5

x = 10

Answer:

x = -11

Step-by-step explanation:

First, get rid of parentheses:

5 + x - 2 = -8

Then, simplify:

3 + x = -8

Finally, subtract 3 on both sides:

x = -11

Hope this helps ^^

Answer:

x = -11

Step-by-step explanation:

5+(x-2)=-8

3+x = -8

Subtract 3 from each side

3+x-3 = -8-3

x = -11

Answer:

[tex]\frac{3}{16}[/tex]

Step-by-step explanation:

We do the division first because of PEMDAS.

Apply the fraction division rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]

Therefore,

[tex]\frac{5}{8}-\frac{1}{4}\div \frac{4}{7}=\frac{5}{8}-\frac{1}{4}\times \frac{7}{4}[/tex]

Multiply the two fractions:

[tex]\frac{5}{8} -\frac{1\times \:7}{4\times \:4}[/tex]

[tex]\frac{5}{8}-\frac{7}{16}[/tex]

The LCM of the denominators (8 and 16) is 16.

Adjust fractions:

[tex]\frac{10}{16}-\frac{7}{16}[/tex]

Subtract:

[tex]\frac{10-7}{16}[/tex]

[tex]\frac{3}{16}[/tex]

Just plug -2 into x

f(-2) = 2(-2)^2 + 4(-2) + 5

Simplify the right side

f(-2) = 8 - 8 + 5

Combine like terms

f(-2) = 5

Greetings from Brasil...

Let's add all the values on one side and make it equal to the sum of all the other values on the other side

(- X) + (- X) + (- X) + (- X) + (- X) + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1  =  X + X + X + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1)

- 5X + 12 = 3X - 8

- 5X - 3X = - 8 - 12

- 8X = - 20    x(- 1)

8X = 20

X = 20/8

1 d.p:

4.03834 = 4.0

24.8845 = 24.9

0.62346 = 0.6

2.3999 = 2.4

The 1 d.p is the first number after the decimal point and to write it as 1 d.p you need to round it off.

2 d.p:

4. 03834 = 4.04

24.8845 = 24.88

0.62346 = 0.62

2.3999 = 2.40

The 2 d.p is the second number after the decimal point.

3 d.p:

4.03834 = 4.038

24.8845 = 24.885

0.62346 = 0.623

2.3999 = 2.400

The 3 d.p is the third number after the decimal point.

y-intercept and slope

Step-by-step explanation:

When we graph a line using slope and y-intercept, the first point that you graph is  y-intercept.

What is Mathematical equation ?

By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.

So, When we graph a line using slope and y-intercept, the first point that you graph is  y-intercept.

Let, consider the equation of y = mx+c, where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.

Therefore, When we graph a line using slope and y-intercept, the first point that you graph is y-intercept.
