Can someone help me please

Answer: In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 − 2xy + c is an algebraic expression.

Step-by-step explanation:

Answer:

An algebraic expression includes variables. Variables are letters that stand for a potential number; most commonly you see x, y, and z used but you can use any letter. Constants are also common in algebraic expressions, and are numbers that are added or subtracted, as well as coefficients, which are what you multiply the variable by.

For example:

3x + 1

Here, the variable is x. The constant is 1. The coefficient is 3.

These are different then other expressions because of the addition of variables. 4 + 4 is not an algebraic expression, but 4x + 4 is.

Algebraic expressions also do not have equal signs, they are not equations.

They can also be more complicated than the ones I've expressed already. 3x^4 + 2x^2 + 4 is an algebraic expression too.

Hope this helps!

[tex]\frac{5}{9}[/tex] of 54 are the ones which have chocolate , so we need to multiply the fraction by 54

[tex]\frac{5}{9} *54 =30[/tex]

Since 30 pieces of candy have chocolate, then 24 don't have it. [tex]\frac{2}{3}[/tex] of the last number are the ones which have gum, multiply [tex]\frac{2}{3}[/tex] by 24 to get the answer:

[tex]\frac{2}{3} *24=16[/tex]

The answer is : 16 pieces of candy have gum

PLEASE MARK ME AS BRAINLIEST

The number of pieces of gums are 16.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, Amelia collected 54 pieces of candy during Halloween.

Of those 54 pieces, five-ninths had chocolate in them.

Number of chocolates = 5/9 ×54

= 30

Remaining candies =54-30

= 24

Two-thirds of the ones that didn't have chocolate were gum.

Now, 2/3 ×24

= 16

Therefore, the number of pieces of gums are 16.

Answer:

Micaela rented the bike for 5 hours.

Step-by-step explanation:

Micaela paid $36 to rent a bike in Natasha's Bikes, where they charge a fixed fee of $16 plus $4 per hour.

We need to find the number of hours Micaela rented the bike.

From the $36 she paid, $16 was used to pay the fixed fee. Thus, the difference $36-$16=$20 was used to pay for the hours of rent.

Since the rate per hour is $4, then the number of hours is $20/$4 = 5 hours.

Micaela rented the bike for 5 hours.

Answer:

r < 35 or r ≥ 43

Step-by-step explanation:

We are told that when the bus driver leaves her first stop by 7:00 a.m., her route will take less than 35 minutes.

Since the time it takes to drive the route is r, then;

r < 35

Also, If she leaves after 7:00 a.M., she estimates that the same route will take no less than 43 minutes. Thus;

r ≥ 43

Thus;

r < 35 or r ≥ 43

Answer:

(x-2)(x-6)

Step-by-step explanation:

We look for two integers which multiply to +12 but add to -8 and we find those numbers by looking at the factors of 12={1,2,3,4,6,12}

We find that by picking 6 and 2,6×2=12 but 6+2 is not -8 so we tweak that as -6 and-2

By so doing, now -6×-2=12,-6+(-2)=-8

so we factor to get (x-2)(x-6)

Complete question :

Lilian purchased a violin form smash music stores. It regularly sold for $670, but wa son slaw for 10% off. She also had to pay 8% sales tax. She bought it on the installment plan and paid 15% of the total cost with tax as a down payment. Her payments were $58 per month for one year. What is her sales tax?

Answer:

$48.24

Step-by-step explanation:

Given that:

Sales price = 670

Discount = 10% off

Sales tax = 8%

Discounted price = (1 - 0.1) * 670

Discounted price = 0.9 * 670 = $603

Hence, purchase price = $603

Hence, sales tax = 8% of purchase price

8% of $603

0.08 * 603 = $48.24
