Answer:

There are 90 coins in the bag.

Step-by-step explanation:

Let [tex]x[/tex], [tex]y[/tex] the number of dimes and quarters. Now we proceed to translate each relevant sentence into mathematical expressions:

(i) The number of quarters is 6 more than twice the number of dimes:

[tex]y = 2\cdot x + 6[/tex] (1)

(ii) There are a total of 276 coins in the bag:

[tex]x + y = 276[/tex] (2)

By applying (1) in (2), we find that the number of dimes is:

[tex]x+2\cdot x + 6 = 276[/tex]

[tex]3\cdot x = 270[/tex]

[tex]x = 90[/tex]

There are 90 coins in the bag.

Answer: As x -> ♾, h(x) -> -♾, and as x -> -♾,h(x) -> -♾

Step-by-step explanation:

The end behavior is x ----> ∞ then h(x) ----> -∞, and when x ----> -∞ then h(x) -----> -∞.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

h(x) = -7[tex]x^6[/tex] + 3 [tex]x^4[/tex]– 5x².

If we plot the Equation on the Graph we can see a parabolic Curve.

This Curve tells as x tends to ∞ the value of h(x) tends to -∞.

and, when x tends to -∞ the value of h(x) tends to -∞.

Hence, the end behavior is x ----> ∞ then h(x) ----> -∞.

and, when x ----> -∞ then h(x) -----> -∞.

Answer:

Incorrect

Step-by-step explanation:

150 students are 100%,

82 students are x%

(82*100)/150=54,67%, so  that is more than half of all students

Answer:

Marco is NOT correct

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

4 (x + 6) - 3x = 26

solve the parenthesis

4x + 24 - 3x = 26

subtract 24 from both sides to get x by itself

4x - 3x = 2

•°•a=-2(negative integer)

The value of the unknown integer is -2.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given data eight times the square of a negative integer plus 24 times the negative integer equals 80 in the form of the mathematical expression will be written as:-

8(-a)²+24-a=80

8a²-24a=80

8a²-24a-80=0

8(a²-3a-10)=0

a²-3a-10=0

a²-(5-2)a-10=0

a²-5a+2a-10=0

a(a-5)+2(a-5)=0

(a-5)(a+2)=0

a-5=0

a=5 or, a+2=0 a=-2

Therefore, the value of the unknown integer is -2.

If the gas prices haven't changed, will Spencer be able to get more gas at Fuel Stop than at Gas World

A number system is defined as a system of writing to express numbers.

Given,

Spencer bought gas for his four-wheeler from Gas World on Saturday

He bought the same amount of gas from Fuel Stop for less money on Sunday

Now, Spencer has $20 to spend on gas for his car.

since the gas cost less money at fuel stop, the gas is cheaper at fuel stop at gas world. spencer has $20 to spend on gas for his car at fuel stop. since the gas is cheaper at fuel stop, spencer will get MORE gas from fuel stop with his money.

Hence if the gas prices haven't changed, will Spencer be able to get more gas at Fuel Stop than at Gas World

Answer: (13 + y) / 5

Step-by-step explanation:

Since Grandma Gertrude gave 13 pieces of jewelry and Grandma Fien gave y pieces of jewelry to the Carlson sisters, the total jewellery given to the sisters will be:

= 13 + y

Since there are 5 Carlson sisters, the number of pieces of jewelry that each sister receive will be:

= Total jewelries / Number of sisters

= (13 + y) / 5

Answer:Grandma Gertrude gave 131313 pieces of jewelry and Grandma Fien gave yyy pieces, so the sisters received a total of 13+y13+y13, plus, y pieces of jewelry.

The sisters divided the 13+y13+y13, plus, y pieces of jewelry evenly among themselves, and there were 555 sisters. So each sister received \dfrac{13+y}{5}

5

13+y

​

start fraction, 13, plus, y, divided by, 5, end fraction pieces of jewelry.
