A truck's position relative to a Carr's position is 60 feet. The car and the truck move in the same direction, but the car moves 5 feet per second faster for 8 seconds. What operation could be used to find the truck's relative position after 8 seconds?
In linear equation ,The truck's relative position with respect to the car is 100 feet
What is linear equation ?
An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.If the truck is moving at a seed "V" then its position after 8 seconds is going to be:
XT = V* t = V * 8 = 8 V
The car, which is initially 60 feet ahead of the truck and starts moving at 5 m/s faster than the truck, would have a speed given by: V + 5
And its position (relative to the truck's) would be:
XC = 60 + (V + 5) * t = 60 + (V + 5) * 8 = 60 + 40 + 8 V = 100ft + 8 V
then the position of the truck relative to that of the car would be given by the difference:
XT - XC = 8 V - (100 +8 V) = 8 V - 8 V - 100ft = -100 feet

Answer:
x = 19
Step-by-step explanation:
The two angles shown here are congruent, so we will set them equal to each other. We will solve for x in the equation:
4x + 18 = 6x - 20
Subtract 4x from both sides:
18 = 2x - 20
Add 20 to both sides:
38 = 2x
Divide by 2 on both sides:
19 = x
So, the answer is “x = 19”

Dave Bowers collects U.S. gold coins. He has a collection of 43 coins. Some are $10 coins, and the rest are $20 coins. If the face value of the coins is $640. how many of each denomination does he have?
Answer:
There are 22 $10 coins and 21 $20 coins.
Step-by-step explanation:
Let x = the number of $10 coins
Let y = the number of $20 coins
You have two unknows so you need two equations.
x + y = 43
10x + 20y = 640.
Rewrite the first equation solving for x
x + y = 43
x = 43 - y Substitute 43 - y in for x in the second equation.
10x + 20 y = 640
10(43 - y) + 20y = 640
430 - 10y + 20y = 640 Subtract 430 from both sides of the equation
-10y + 20y = 210 Combine the y's
10y = 210 Divide both sides by 10
y = 21 This is the number of $20 coins.
Substitute 21 in for y in either of the original equations to solve for x
x + 21 = 43 Subtract 21 from both sides
x = 22 This is the number of $10 coin.
Check:
Substitute in 21 for y and 22 for x
x + y = 43
21 + 22 = 43
43 = 43 checks
10x + 20y = 640
10(22) + 20(21) = 640
220 + 420 = 640
640 = 640 Checks

The equation that can be used to determine the cost of one drink is 2x = 6.09
The sum of the prices for the movie tickets, refreshments, and voucher represents the total sum that Stephen and Paul will be required to pay.
Therefore,
The total amount paid is equal to the cost of two tickets + cost of the two drinks - coupon
So,
( 11 × 2 ) + ( x × 2 ) - 5 = 29.18
22 + 2x - 5 = 29.18
Subtracting 22 from each side of the equation.
22 + 2x - 5 - 22 = 29.18 - $22
2x - 5 = 7.18
Adding 5 on each side of the equation.
2x - 5 + 5 = 7.18 + 5
2x = 12.18
Now, divide each side of the equation by 2.
x = 6.09
Hence, the cost of one drink is $6.09

in a classroom there are 56 boys and 72 girls, find the ratio of girls to the total number of students.
Answer: [tex]\frac{9}{16}[/tex]
Step-by-step explanation:
We need to find the ratio of girls to the total number of students. That means our ratio is going to be 72 (the number of girls) over 56+72 (boys + girls, the total number of students).
When you add 56+72, you'll get 128 in the denominator. Continuing to simplify the fraction, you'll end up with:
[tex]\frac{72}{128}[/tex] = [tex]\frac{9}{16}[/tex]
Depending on what format your teacher wants, this can be written as [tex]\frac{9}{16}[/tex] or 9:16.
Two buckets of paint have the same mass and temperature. They are combined into one larger bucket. The larger bucket starts at the same temperature as the paint. The larger bucket of paint has the same temperature as the original buckets of paint.
The amount of thermal energy in the larger bucket of paint is about ________ the amount of thermal energy in each of the smaller buckets of paint.
Is the space the same as, twice, or one-half?
The larger bucket paint contains roughly the same amount of thermal energy as each of the smaller buckets of paint.
What is defined as the thermal energy?Thermal energy is the energy possessed by a substance or system as a result of particle movement within the object or system.
Thermal energy is one of several types of energy, with 'energy' characterized as 'the capacity to do work.'Thermal energy is a form of kinetic energy, that is energy due to motion, because it is caused by particle movement. Thermal energy causes something to have an internal temperature, which can be measured.As, the thermal energy is due to the kinetic energy.
Thus, the kinetic energy of an object is directly proportional to its mass; thus, doubling the mass doubles the kinetic energy.
In, the given case, the paint contained in the two buckets are combined.
Thus, the mass is remained constant.
The larger bucket also have the the same temperature. thus, the thermal energy will not change.
Therefore, the amount of thermal energy with in larger bucket of paint is roughly equal to the amount of thermal energy in all of the smaller buckets of paint.

8x-28°=180°
8x=180°-28°
8x=152°
[tex] \frac{8x}{8} = \frac{152}{8} \\ x = 19[/tex]
Answer:
x=26
Step-by-step explanation:
since we are adding, you start by combining like terms. x's with x's and #'s with #'s. that leaves you with 8x-28=180. Your next step is to get x all by itself so you move the -28 to the other side by adding 28 to both parts. that leaves you with 8x=208. now you still have to get x by itself and right now its being multiplied with the 8 so to get rid of it you divide by 8 on both sides and that leaves you with x=26.

How to Apply the Vertical Angles Theorem?Based on the vertical angles theorem, the vertical angles AIZ and GIM are congruent to each other.
Therefore:
7. m<AIZ = m<GIM
Substitute
3x - 56 = x + 2
3x - x = 56 + 2
2x = 58
x = 29
8. 4z + 7 + x + 2 = 90 (complementary angles)
Plug in the value of x
4z + 7 + 29 + 2 = 90
4z + 38 = 90
4z = 90 - 38

Given, the mid-point of AB is M = (6 , ₋1) and
the coordinates of B is (8 , ₋7)
we know that midpoint formula is:
(x₁ ₊ x₂/2 , y₁ ₊ y₂/2) = M(x , y)
let the points be:
A (x, y) = (x₁ , y₁)
B (8 , ₋7) = (x₂ , y₂)
mid point M = (6 , ₋1)
(x₁ ₊ x₂/2 , y₁ ₊ y₂/2) = M(x , y)
substitute the above values in the formula:
(x ₊ 8/2 , y ₊ (₋7)/2) = (6 , ₋1)
x ₊ 8/2 = 6 and y ₋ 7/2 = ₋1
x ₊ 8 = 12 and y ₋ 7 = ₋2
