Answer:

-6/7p + 1/7

Step-by-step explanation:

Like Terms: terms that have the same variables and powers

In this equation the like terms are -4/7p and -2/7p

First solve that, which will be -6/7p + 1/7

You have to leave the 1/7 alone because there aren't any more numbers with no variables.

Answer:

Step-by-step explanation:

You can only combine terms that are the same, which means you can only combine the fractions with p attached. A + and - make a -. The second fraction changes to negative or subtraction which ever way you want to say it.  -4 - 2 = -6 and the bottom number always stays the same  and you keep the letter attached. You can not combine 1/7 because it does not have a p attached. You would leave it the same. [tex]\frac{-6}{7}p +\frac{1}{7}[/tex]

Answer:

7 , 8 , 9

Step-by-step explanation:

Assume three consecutive number are,

x , (x+1) , (x+2)

Multiplied by 2 ,3 and 4 respectively

2x , 3(x + 1) , 4(x + 2)

Sum of all = 74

So,

2x + 3(x + 1) + 4(x + 2) = 74

2x + 3x + 3 + 4x + 8 = 74

9x + 11 = 74

9x = 63

x = 7

So,

x , (x+1) , (x+2)

7 , (7+1) , (7+2)

7 , 8 , 9

Answer:

5 months

Step-by-step explanation:

Jason's original weight = 120 pounds

Let the no. of months be m

If he gains 10 pounds in each moth , then his weight in m months will be = 10m

His total weight will be= 120+10m  -----(1)

Gerardo's original weight = 150 pounds

If he gains 4 pounds in each month , then his weight in m months will me =4m

His total weight will be = 150+4m-----(2)

Equating (1) ans(2)

120+10m=150+4m

=>10m-4m=150-120

=>6m=30

=>m=[tex]\frac{30}{6}[/tex]

=>m=5

It will take 5 months for Jason to weigh the same as Gerardo

Answer:

The first term is a = 0.4.

Step-by-step explanation:

We are given the indicated terms of an arithmetic sequence; [tex]a_3[/tex] = 1, [tex]a_3_3[/tex] = 22.

As we know that the nth term of the A.P. is given by;

[tex]a_n=a+(n-1)d[/tex]

where, a = first term and d = common difference

Now, the third term of AP is given as 1, this means;

[tex]a_3=a+(3-1)d[/tex]

[tex]a+2d=1[/tex]

a = 1 - 2d  --------------- [equation 1}

Also, the 33rd term of AP is given as 22, this means;

[tex]a_3_3=a+(33-1)d[/tex]

[tex]a+32d=22[/tex]

[tex]1-2d+32d=22[/tex]     {using equation 1}

[tex]30d=21[/tex]

[tex]d=\frac{21}{30}[/tex]

d = 0.7

Putting the value of d in equation 1 we get;

[tex]a=1-(2 \times 0.7)[/tex]

a = 1 - 1.4 = -0.4

Hence, the first term of an AP is -0.4.

Answer:

-7x^4+13x³-6x²-4x+0.25

Step-by-step explanation:

Do you just have to combine like terms?

-7x^4+13x³-6x²-4x+0.25 (assuming I’m reading your exponent notation correctly)

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Or just subtract

9.884 * 10^6 - 1.009 * 10^7=

− 2.05999999 × 10^5

Rounded up is:

Step-by-step explanation:

The opposite of a number is simply the number multiplied by -1 so the opposite of n is -n. "Between -3 and 0" tells us that the inequality is -3 < -n < 0.

Irrational numbers are real numbers, they just aren't rational.

For example:

Answer:

A real number that can NOT be made by dividing two integers (an integer has no fractional part). "Irrational" means "no ratio", so it isn't a rational number. ... Example: π (the famous number "pi") is an irrational number, as it can not be made by dividing two integers.

Answer: To find the perimeter of a shape, we need to add the value of all of the sides. Here, we are given the values:

6cm

20cm

26cm

30cm

36cm

42 cm

All of these added together are equal to 160, so the perimeter of the shape is 160cm.

Answer:

perimeter = 160 cm

Step-by-step explanation:

perimeter = add all sides

perimeter = 6 + 20 + 26 + 30 + 36 + 42

perimeter = 160 cm

Problem 1

To convert from gallons to cups, we multiply by 16 since 1 gallon = 16 cups

Therefore, 4 gallons = 64 cups

==================================================

Problem 3

1 hour = 60 minutes

4 hours = 240 minutes (multiply both sides by 4)

==================================================

Problem 5

100 cm = 1 meter

1 cm = 0.01 meter (divide both sides by 100)

53 cm = 0.53 meter (multiply both sides by 53)

==================================================

Problem 6

1 foot = 12 inches

3 feet = 36 inches (multiply both sides by 3)

1 yard = 3 feet

1 yard = 36 inches

2 yards = 72 inches (multiply both sides by 2)

Answer:

43,000: 4.3×10^4

0.0072: 7.2×10^-3

0.0000901: 9.01×10^-5

Step-by-step explanation:

scientific notation: a×10^b, where should be 0<a<10

Step 1. Count the zeros

Step 2. Look at the number left, and determine whether or not it fits in the range of [a]. If not, we divide or multiply 10 to get it fit

------------------------

43,000: 4.3×10^4 (since 43 does not fit, we divide by 10 to get it fit)

0.0072: 7.2×10^-3 (since 0.72 does not fit, we multiply 10 to get it fit)

0.0000901: 9.01×10^-5 (since 0.901 does not fit, we multiply 10 to get it fit)

Answer:

Y°= 115

D = (3,1)

Step-by-step explanation:

For y, your just looking through the vertex. essentially if its 115 on one side it's going to be the same on the other because it all has to be equal, and that's how vertex's work.

for D. Read the instructions and make a square

Answer: 8 days.

Step-by-step explanation:

Given that Anna can do a job in 4 days. After she has worked for 1 day, she is joined by Sylvia, and it takes them 2 days working together to finish the job.

Since Anna has already worked for 1 day, she would have worked the remaining days for 3 days. But she is joined by Sylvia, and it takes them 2 days working together to finish the job.

That is,

1/3 + 1/S = 1/2

Where S is the number of days Sylvia to do the job being completed in 2 days.

1/S = 1/2 - 1/3

1/S = (3 - 2)/6

1/S = 1/6

S = 6

The job Anna would have done for 3 days, will take 6 days for Sylvia.

The 1 days used by Anna will be 2 days for Sylvia.

Therefore, the total days that will take Sylvia to do the whole job by herself will be 2 + 6 = 8 days

Answer:

No, mn is not even if m and n are odd.

If m and n are odd, then mn is odd as well.

==================================================

Proof:

If m is odd, then it is in the form m = 2p+1, where p is some integer.

So if p = 0, then m = 1. If p = 1, then m = 3, and so on.

Similarly, if n is odd then n = 2q+1 for some integer q.

Multiply out m and n using the distribution rule

m*n = (2p+1)*(2q+1)

m*n = 2p(2q+1) + 1(2q+1)

m*n = 4pq+2p+2q+1

m*n = 2( 2pq+p+q) + 1

m*n = 2r + 1

note how I replaced the "2pq+p+q" portion with r. So I let r = 2pq+p+q, which is an integer.

The result 2r+1 is some other odd number as it fits the form 2*(integer)+1

Therefore, multiplying any two odd numbers will result in some other odd number.

------------------------

Examples:

So there is no way to have m*n be even if both m and n are odd.

The general rules are as follows

The proof of the other two cases would follow a similar line of reasoning as shown above.

Answer:

Measure of the third outgoing current will be 0.34 ampere.

Step-by-step explanation:

Kirchhoff's Current Law states that total current entering a circuit's junction is exactly equal to the total current leaving the same junction.

By this rule,

Sum of input three currents = Sum of three outgoing currents

0.38 + 0.75 + 0.29 = 0.48 + 0.6 + i

1.42 = 1.08 + i

i = 0.34

Therefore, measure of the third outgoing current will be 0.34 ampere.

Answer:

The distance from the centre of the dome is 2000 feet

Step-by-step explanation:

We have an equation representing the distance from the centre of the dome.

We can now make the subject of the formula.

d = 2100 -2(h)

We are asked to find the value of d when the value of h is = 50 feet.

To do this, we simply plug in the value for h into the equation and solve the equation.

d = 2100 - 2(50)

d = 2100 -100

d = 2000 feet.

Hence the distance from the centre of the dome is 2000 feet

Answer: 120

Step-by-step explanation:

Given : Total toppings = 6

Number of toppings needs to be selected = 3

Also if repetition of toppings is not allowed , then the number of combinations are possible = 6 x 5 x 4   [First we choose 1 out of 6 , then 1 out of remaining 5 and then 1 out of 4,then multiplying the choices for 3 toppings]

=  120

Hence, the number of different pizza topping combinations are possible if the maximum number of allowed toppings is 3 is 120 .
