Answer:

Step-by-step explanation:

n-(7+n) which is a strange problem to give you as that is equal to

n-7-n which always equals -7

And that means n can be any real number and the expression still equals -7

The algebraic expression will be -7. x is the assumed algebraic expression. The equation is solved by subtraction.

An algebraic expression is a phrase that has been combined using operations like addition.

Let n is the number and x be the solution for the given condition;

If the number is decreased by 7 then the equitation will be (n-7).

From the given condition;

[tex]\rm x=\rm n-(n-7) \\\\ x=n-n-7 \\\\ x=-7[/tex]

Hence the algebraic expression will be -7.

Answer:

13 quarters, 26 nickels.

Step-by-step explanation:

n will be number of nickels, q will be number of quarters, and we have 39 total coins

so n + q = 39 (number of nickels + number of quarters = 39 coins.

The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)

which means

n + q = 39

2q + q = 39

3q = 39

q = 13

and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels

LMK if you have questions.

If you want to double check the money,

n(0.05) + q(0.25) = 4.55 is the equation to use.

26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55

Answer: (x-4) is not a factor of the given polynomial.

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

Explanation:

Rule: If (x-k) is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem. We can take this in reverse to say that if p(k) = 0, then (x-k) must be a factor of p(x).

In this case, we have k = 4 and we can find that:

p(x) = 2x^4-9x^3-20x^2+147x-180

p(4) = 2(4)^4-9(4)^3-20(4)^2+147(4)-180

p(4) = 24

The result we get is not zero, so that means (x-4) is not a factor of p(x).

Answer:

7.21 units

Step-by-step explanation:

GIven data

Point 1= (8,3)

x1= 8

y1= 3

Point 2=  (2,7)​

x2= 2

y2= 7

The expression for the distance between two points is given as

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((2-8)²+(7-3)²)

d=√((-6)²+(4)²)

d=√36+16

d=√52

d= 7.21

Hence the distance between the points is 7.21 units

Step-by-step explanation:

remember ll means absolute value

the absolute value of x is x and the absolute value of -7 is 7

now we have x+7=8

step 1 subtract each side by 7

7-7 cancels out

8-7=1

we're left with x = 1

Answer:

126 passengers from Trinidad.

Step-by-step explanation:

Given that,

On a BWIA flight, 2/3 of the  passengers are from Trinidad.

Total passengers = 189

We need to find how many were from Trinidad. It can be calculated by finding 2/3 of 189 such that,

[tex]P=\dfrac{2}{3}\times 189\\\\=126[/tex]

Hence, there were 126 passengers from Trinidad.

x + 33° = 180° (It's forming a linear pair that's why the sum is 180°.)

x = 180° - 33°

x = 147°
