The final simplified expression representing the total miles driven in three days is 4x-90.

Let the miles drove on the day 1 be x

A/Q

On day 2 , we drove 10 more than twice the miles driven on day 1 =2x+10

On day 3 we drove 100 miles less than day 1 = x-100

Simplified expression representing the total miles driven in 3 days

day 1 = x miles

day 2 = (2x+10)miles

day 3 = x-100

total = x+2x+10+x-100

= 4x-90

Some "solving" difficulties are related to "simplification" challenges. Some equations, like some expressions, contain parentheticals and even nested grouping symbols. The technique of simplifying is the same whether we're working with expressions (and therefore only simplifying) or equations (and so including solving).

To simplify an expression, write an equivalent expression with no related terms. This implies we'll rephrase the expression with as few terms as feasible.

Solution

x=13+k/z , z≠0

Answer:

Step-by-step explanation:

Solve the equation for x .

zx-13=k

zx−k−13=0

(z)⋅x+(−k−13)=0

x=−(−k−13)/z

x=(k+13)/z

If Amanda distributed 62 pieces of gum among her friends by giving 2 to each friend and she has remaining 8 then we can say that she have 27 friends.

Given that Amanda won 62 pieces of gum and division has been done in such a way that 2 pieces to each friend are given and only 8 has remaining.

We are required to find the number of friends that Amanda have.

If 8 pieces of gums are left then the number of pieces distributed will be 62-8=54 pieces of gums.

Since 2 pieces are given to 1 friend so the number of friends will be=54/2=27 friends.

Hence if Amanda distributed 62 pieces of gum among her friends by giving 2 to each friend and she has remaining 8 then we can say that she have 27 friends.

Joseph could use C), D), and E) to make kebabs without any leftovers:

C) 30 pieces of meat and 40 pieces of vegetables

D) 45 pieces of meat and 60 pieces of vegetables

E) 72 pieces of meat and 96 pieces of vegetables

How were the answers determined? To solve for the answer, here are some pointers:

Consider the given which states that each kebab has 3 pieces of meat and 4 pieces of vegetables, and Joseph wanted to make kebabs without any leftovers - meaning, there should be no extra piece of meat or no extra piece of vegetable.

In choosing which is the answer, make sure that the number of pieces of meat must be divisible by 3 (pieces of meat), and the number of pieces of vegetables must be divisible by 4 (pieces of vegetables). This was also based on the given.

Moreover, the quotient for meat and the quotient for vegetables must be equal to each other so that there will be no leftovers.

Therefore, the answers are C), D), and E) because these three answers satisfy the conditions above.

In linear equation, $1.56 is the price of a pair of sport socks.

What in mathematics is a linear equation?

To find how much it costs for one pair of socks, divide the cost with how many pairs there are.  

12.55/8 = 1.56875

Since we are determining the cost of each pair of socks, it's only justifiable if we round it to the nearest hundredths.

Therefore, a pair of socks cost around $1.56 excluding taxes.

Answer:

im pretty sure its  -20

Step-by-step explanation:

Based on the Alternate Interior Angles Theorem, the degree measure of angle 3 is equal to 153.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent.

Since line a and m are parallel lines, angle 4 and 6 are alternate interior angles. Therefore, by applying the supplementary angle theorem, the measure of angle 6 is given by:

Q + R = 180°

153° + m<6 = 180°

Angle 6 = 180° - 153°

Angle 6 ≡ Angle 4 = 17°

Now, we can determine the degree measure of angle 3 by applying the supplementary angle theorem:

Q + R = 180°

17° + m<3 = 180°

Angle 3 = 180° - 17°

Angle 3 = 153°

The equation of the line that is parallel to y = 4x ₊ 3 and passes through the point (2,6) is  y = 4x ₋ 2.

The slope of the preceding equation is 4 because it is in slope intercept form. The slope of an equation is always equal for parallel lines, hence the slope of the equation we are requested to create is also 4.  We are given that this line passes through (2,6).

In the absence of intersection, two lines are said to be parallel. Each line has the same slope. In the event where m₁=m₂, f(x)=m₁x+b₁ and g(x)=m₂x+b₂ are. parallel

In order to write in y = mx +b form, we need to solve for b (the y-intercept).  

Given, x=2, y=6, and m = 4.

6 = (4) (2) ₊ b

simplify

6 = 8 ₊ b

solve for b.

b = 6 ₋ 8

b = ₋2

So the equation of the parallel line is   y = 4x ₋ 2

Hence we get the equation of the line that is parallel to y = 4x ₊ 3 and passes through the point (2,6) is y = 4x ₋ 2

The correct answer is 812 and 2/5 feet.

Convert the mixed fraction into improper fraction.

Distance between the bottom of canyon and sea level = 59 and 9/ 10 feet= 599/10 feet

Distance between the bird's nest and sea level = 752 and 1/2 feet = (752×2 + 1) feet =1505/2 feet

So, the difference between elevation between the bottom of the canyon and the bird's nest = 599/10 + 1505/2 feet

= 59.9 + 752.5 feet = 812.4 feet

= 812 and 4/10 feet

= 812 and 2/5 feet

Hence, the difference between elevation between the bottom of the canyon and the bird's nest is 812 and 2/5 feet .

Step-by-step explanation:

If we want to have solutions for the linear equation, the value of A must be 4,

Let's define A as the number that should be in the box, now we can write the linear equation in the image as:

A*(5x + 6) = 20x + 24

We want to find the value of A, if we divide both sides by 5x + 6 we will get:

A = (20x + 24)/(5x + 6)

The numerator can be rewritten as:

20x + 24 = 4*(5x + 6), replacing that we will get:

A = 4*(5x + 6)/(5x + 6) = 4

Then we conclude that, if we want to have solutions for the linear equation, the value of A must be 4.

We are given that:

Frances has no money in her account.

Current balance of her account = $ 0

Now she wrote 3 checks of $ 35 each.

Amount written = 3 × $ 35 = $ 105

Now, the balance in her account will be = $ 0 - $ 105 = - $ 105

Also, the bank has imposed a penalty of $ 15 as she has overdrawn her account.
