Answer:
[tex]\boxed {x = -15}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]x + 7 = -8[/tex]
-Subtract both sides by [tex]7[/tex]:
[tex]x + 7 - 7 = -8 - 7[/tex]
[tex]\boxed {x = -15}[/tex]
So, the value of [tex]x[/tex] is [tex]-15[/tex].

Albania is an Eastern European country that uses a currency called the Albanian Lek (ALL). Right now, $1 (1 USD) exchanges for 106.40 ALL. How many dollars (USD) could you exchange for 1,000,000 ALL? Answer: 1,000,000 ALL = _______ USD. Round your answer to two (2) decimal places. *
Answer:
$9398.50
Step-by-step explanation:
Given
[tex]\$1 = 106.40\ ALL[/tex]
Required
Equivalent of 1,000,000 ALL
We have:
[tex]\$1 = 106.40\ ALL[/tex]
and
[tex]\$x = 1000000\ ALL[/tex]
Cross Multiply
[tex]x * 106.40 = 1 * 1000000[/tex]
[tex]106.40x = 1000000[/tex]
Solve for x
[tex]x = 1000000/106.4[/tex]
[tex]x = \$9398.50[/tex] -- Approximated

Answer:
x = 54angle ACD = 124°Step-by-step explanation:
The rule is that the exterior angle (ACD) is equal to the sum of the remote interior angles (the two marked angles on the right).
You are expected to use this relation to write and solve an equation.
exterior angle = angle D + angle B
(2x +16) = 58 + (x+12)
2x +16 = x +70
x + 16 = 70
x = 54
Then angle ACD is ...
angle ACD = (2x +16)° = (2·54 +16)°
angle ACD = 124°

Write the equation of a line that is perpendicular to y = 0.25x - 7 and that passes through the point (-6,8).
Answer:
y = -4x -16
Step-by-step explanation:
Line perpendicular have the slope = -1/m
Substitute the values,
8 = (-4)(-6) + c
8 = 24 + c
c = -16
Thus, the equation of the perpendicular line is y = -4x-16

Translate One-third of a number is 14 into an equation
Answer:
1/3x=14
answer for x is 42
Step-by-step explanation:
x represents the original number and 1/3 of the number equals 14. So 1/3x=14
So therefore 1/3x=14 which x = 42 in case if you were wondering.
A store is marking down the price of a television 25 percent from the original price of $250. Which expression can be used to find the marked down price?
Answer:
250 × 0.25
Step-by-step explanation:
x/250 × 25/100
cross multiply
100x = 250 × 25
100x = 6250
divide by 100
x = 62.5
62.5 is how much the price got marked down
original price - marked down amount = new discounted price
250 - 62.5 = 187.5
$187.50 is now the actual price
As for which expression can be used to find the marked down price, none are listed in this problem and I'm assuming its a multiple choice question considering the wording of "which"
how i solved it is through cross multiplication but another way is by using the expression:
250 × 0.25
this is because 25% equals 0.25

A pilot planning to fly at 420 miles per hour flies against a wind which cuts the speed to 4/5 of the planned speed. How long
will it take the plane to travel 840 miles?
Answer:
2.5 hours
Step-by-step explanation:
420x4/5=336
840/336=2.5
Answer
2.5 hours
Step-by-step explanation:
4/5 of 420 is 336 mph
840 ÷ 336 = 2.5 hours
The half-life of a certain radioactive material is 36 days. An initial amount of the material has a mass of 487 kg. Write an exponential function that models the

: 0 kg
Answer:
a(t) = 487(1/2)^(t/36)a(5) = 442.302 kgStep-by-step explanation:
The exponential function for half-life problems is easily written using 1/2 as the base of the exponent.
present value = (initial value) × (1/2)^(t/(half-life))
Then the amount (a) remaining after t days is ...
a(t) = 487 × (1/2)^(t/36)
__
After 5 days, the amount remaining is ...
a(5) = 487×(1/2)^(5/36) ≈ 442.302 kg
_____
Some folks like their exponential function to be written using e as the base for the exponent. Here, that would be ...
a(t) = 487·e^(-0.019254t)
where the constant in the exponent is -ln(2)/36.
theKiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away. How long was the ride from kileys house to the airport?

Two fitness clubs are asding new members. Fitness club A cutrently has 450 memebers and adds 15 nee memeners each month. Fitness club B currently has 400 members amd adds 25 new members each month. After how many months will fitness club A and B have the samr number of members?
Answer:
It will take 5 months for the two fitness clubs to have the same number of members
Step-by-step explanation:
Let the number of months it takes fitness club A and B to have the same number be = x
For the two clubs to have the same number in x months, that means we can set up an equation as follows
450 +15x = 400 + 25x
Grouping like terms
450 - 400 = 25x -15x
50 = 10x
x= 5
Therefore, it will take 5 months for the two fitness clubs to have the same number of members

The observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground. The express elevator travels nonstop from the ground floor to the observatory on the top floor at a rate represented by the equation y=30x, where y is the height, in feet, and x is the number of seconds.
Answer:
Step-by-step explanation:
Given the rate at which the elevator travels modeled by the expression;
y = 30x where y is the height, in feet, and x is the number of seconds.
If the observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground, we can calculate the time taken to reach the top floor by substituting y = 900 into the equation and solve for x as shown;
y = 30x
900 = 30x
Rearrange
30x = 900
Divide both sides by 30
30x/30 = 900/30
x = 30
Hence it takes 30seconds for the elevator to reach the top floor

1) Select the characteristics that are true of all parallelograms. Group of answer choices Opposite sides are never equal. Opposite angles are congruent (equal). A parallelogram can have more than 4 sides. Parallelograms have 4 sides. Opposites sides are parallel and equal in length.
Answer:
- Opposite angles are congruent (equal).
- Parallelograms have 4 sides
- Opposites sides are parallel and equal in length.
Step-by-step explanation:
A parallelogram is a quadrilateral and since quadrilaterals are fur sided figures, hence parallelograms are also four sided figures.
A parallelogram has its opposite side equal and parallel to each other with a slanting edge at two of its sides. Since its opposite sides are equal hence its opposite angles are also equal.
Parallelogram cannot have more than four sides because they are quadrilateral. Find the diagram of a parallelogram in the attached figure.
It can be seen from the attached figure that AB//CD and AD//BC
