What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants. An algebraic expression is a combination of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

The variables represent unknown or unspecified values that can take on different numerical values, while the constants are specific, fixed values that do not change.

The mathematical operations are used to manipulate the variables and constants and to create different algebraic expressions.

Given expression ,

[tex](-3m^5)(–2m^4)[/tex]

we know that [tex]a^m * a ^n = a ^ (m+n)[/tex]

[tex](-3m^5)(-2m^4) = 6m^(5+4)[/tex]

= [tex]6m^9[/tex]

Therefore, the answer is [tex]6m^9[/tex] in standard form.

Answer:

$16.50

Step-by-step explanation:

Total cost: $70.40

Per CD w/ tax: $70.40 ÷ 4 = $17.60

Price of CD w/out tax: $17.60 - $1.10 = $16.50

Answer:

50 can go into 250 (5 TIMES)

Step-by-step explanation:

Its very simple. Keep adding 50 untill you get 250

50+50+=100+50=150+50=200+50=250

Answer:

y=11

Step-by-step explanation:

To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.

To Check your answer:

Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.

Answer:

y=11

Step-by-step explanation:

you have to divide both sides of the equation by the same term and then simplify

Answer:

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

Step-by-step explanation:

Step(i):-

Given that 74% of 19 -year -old males are at least 172 pounds

Let 'X' be a random variable in a binomial distribution

P( X≥172) = 74% = 0.74

we have to find that the percentage of males are not at least 172 pounds

Step(ii):-

The probability of males are not at least 172 pounds

P(X⁻≥172) = 1- P( X≥172)

                 = 1- 0.74

                 = 0.26

Final answer:-

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

lordddd is this Geometry?

Step-by-step explanation:

Answer:

DB!

Step-by-step explanation:

Because if you multiply them out, they both equal 6k-30.

-6(5-k)=-30+6k, which is equal to 6k-30.

Hope I helped!

because you can use the distributive property with

-6(5-k)

-6×5= -30

-6×-1k= 6k

so that equals 6k-30

Answer:

Slope = -3/1

Step-by-step explanation:

As the hint says, slope is the change in y over the change in x or

m = (y2 - y1)/(x2 - x1)

m = (9 - 15)/(2 - 0)

m = -6/2

m = -3/1

Answer:

35p - 14u + 49

Answer:

15 hours

Step-by-step explanation:

3: 3, 6, 9, 12, 15

5: 5, 10, 15, 20

15 is the lcm of 3 and 5

Answer:

15 hrs

Step-by-step explanation:

Time for One pipe = 3 hrs

Amount of tank it can fill in 1 hr = 1/3

Time for Second  pipe = 5 hrs

Amount of tank it can fill in 1 hr = 1/5

Tank they can fill together in 1 hr = 1/3 x 1/5= 1/15

Time it takes to fill full tank = 15/1

I hope im right!!

Answer:

1/4 * 1/2 = 1/8

Step-by-step explanation:

1/4 chance of choosing an 'm'

Answer:

q = x + 3

Step-by-step explanation:

q = (x^2 + 7x + 12)          factor the numerator

    ============

         x + 4

q = (x + 3)(x + 4)

        ========

          (x + 4)

Notice that the x + 4's cancel

q = (x + 3)

Step-by-step explanation:

using the fact that a straight angle is always 180:

180-34=a

a=146

Answer:

146°

Could you please give me brainliest, I really need it.

Step-by-step explanation:

Supplementary angle: Two angles that add up to 180°

Given angle: 34°

180°-34°= 146°

Answer:

13. 5 years

Step-by-step explanation:

First, convert R percent to r a decimal

r = R/100

r = 6.8%/100

r = 0.068 per year,

Then, solve our equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(182,800 / 75,000) / ( 1 × [ln(1 + 0.068/1)] )

t = 13.542 years

Summary:

The time required to get  a total amount of $ 182,800.00  from compound interest on a principal of $ 75,000.00  at an interest rate of 6.8% per year  and compounded 1 times per year  is 13.542 years. (about 13 years 7 months)
