Mark is 18, as his 8th birthday was 10 years ago
Aunt Jess is 36 since Jess is twice as old as Mark
Julie is 28 because 36+18=54, and 54-26=28
Gwen is 30 since she's 2 years older than Julie
The twins are 8 (1/3 of 30 is 10, then do -2)
Answers:
1. 8

3. Mark will be 23
4. Gwen was twice Julie's age when she was 4 (26 years ago)
(Gwen is 2 years older than Julie)
I hope this helps, Brainliest and Thanks would be very much appreciated
Answer: 1. 8 years old
2. 10 years
3. 23 years old
4. 26 years ago
Step-by-step explanation:
G=Gwen's age.
J=Julie's age.
A=Aunt Jess's age
U=Uncle Mark's age
T=twins' ages
1. G=J+2
A=U*2
J=A+U-26
T=G/3 - 2
U-10=8
U+10-10=8+10 ==> Add 10 on both sides to single out U.
U=18
A=U*2
A=18*2
A=36
J=A+U-26
J=36+18-26
J=54-26
J=28
G=J+2
G=28+2
G=30
T=G/3 - 2
T=30/3 - 2
T=10-2
T=8 ==> 8 years old
2. 8+x=18
8-8+x=18-8
x=10 years
3. U=18
18+5=23 years old
4. G=J+2
G=J*2
J*2=J+2
2J=J+2
J=2 ==> subtract J on both sides
G=2+2
G=4
30-4=26 years ago

Answers
1.5·10⁸ kilometers
As a result, the Earth Sun distance is 150 million kilometers. To use scientific notation, pick a value between 1 and 10, then multiply it by 10ˣ.
So the number between 1 and 10 in 150,000,000 is 1.5, with 8 decimal points.
As a result, the solution is 1.5·10⁸
State the distance between The Earth and The Sun?
The benefits of Earth's prime placement in the solar system are numerous. We are just far enough away from the Sun for life to thrive.
Venus is excessively hot. Mars is quite chilly. Scientists refer to our region of space as the "Goldilocks Zone" because it looks to be ideal for life.
As previously stated, Earth's average distance from the Sun is around 93 million miles (150 million kilometers). That's one AU.
On this hypothetical scale, these so-called "linebackers" resemble minuscule specks rather than the massive linebackers of the NFL.
If all of the known asteroids in our solar system were combined, their total mass would be less than 10% that of Earth's moon.

Employees at company p sent 6.1 x 10^4 emails this year doing company business, compared to employees at company c, who sent 191,00 emails. find the difference in the numbers of emails sent by each company. answer in scientific notation without units. the coefficient may be exact or rounded to 2 decimal places.
Answers
The difference in the numbers of emails sent by each company is 4.19 × 10⁴.
The number of emails sent by company p = 6.1 × 10⁴
Converting scientific notation to real number
The number of emails sent by company p = 6.1 × 10000
Performing multiplication
The number of emails sent by company p = 61,000
The number of emails sent by company c = 191,00
Finding the difference using subtraction operation
Difference in number of mails = 61000 - 19100
Performing subtraction
Difference = 41,900
Converting the real number in scientific notation
Difference = 4.19 × 10⁴
Hence, the difference in the numbers of emails sent by each company is 4.19 × 10⁴.

How to carry out transformation reflection?
From the given first image, we see that it is in the first quadrant but by the second image, we see that it is now mirrored along the horizontal axis. Thus, we can say that it is reflected across the x-axis.
After reflection, across the x-axis, we see that it was translated down by 2 units.
The last transformation is that we see it is now in quadrant 3 which means it was now reflected across the y-axis.

there were twice as many four-door cars as two-door cars in the parking lot. there were 36 cars in the lot. how many had four doors? how many had two doors?
Answers
the number of two door cars in the parking lot is 12 and the number of four door cars in the parking lot are 24.
We are given that the number of four door cars in a parking lot is equal to twice the two door cars.
Let the two door cars be x
Four door cars = 2 x
Also, we are given that total cars = 36
So, we get the equation:
x + 2 x = 36
3 x = 36
x = 36 / 3
x = 12
Two door cars = x = 12
Four door cars = 2 x = 2 ( 12) = 24
Therefore, we get that, the number of two door cars in the parking lot is 12 and the number of four door cars in the parking lot are 24.

Answers
There is 17.5 inches distance between the tee and the hole on the model.
According to the question we have been given that
length of hole#9 is = 175 yards
the scale for the model is given as = 2 inch : 20yards
We need to find the inches between the tee and the hole.
Let the length between the tee and the hole on the model be x inches
Thus the above condition can be written as
2 inches / 20yards = x inches/175 yards
We have to solve this proportion for x we get
x inches = 175*2/20
x = 17.5 inches
Hence there is 17.5 inches distance between the tee and the hole on the model.
