Two years ago a man was five times as old as his son. Two years later his age will be eight more than three times as old as his son . Find there present age
Answer:
The age of man is 42 years and the age of his son is 10 years.
Answer: Father 42 and son 10
Let the age of the father is x years and that of the son is y years.
Then by the given question,
x-2=5(y-2)
or, x-5y=-10+2
or, x-5y=-8
or, x=5y-8
x+2=3(y+2)+8
or, x-3y=6+8-2
or, 5y-8-3y=12
or, 2y=12+8
or, y=20/2
or, y=10
then x=5y-8=50-8=42
Then, the age of father is 42 yrs. and the age of sun is 10 yrs.
jake travels 6 hours for a total of 444 miles on 20 gallons of gas, rate for gallons and hours.
Answer: 5 gallons per hour.
Step-by-step explanation: To find the unit rate, divide "gallons" by "hours." As we said, we need to find the unit rate. We want a unit rate where 1 is in denominator, so we divide the top and bottom by 6. (Remember, unit means 1.)
[tex]\frac{30/6}{6/6}=\frac{5}{1}[/tex]
Therefore, our answer is 5.

BREATHING IN THE DARK, LYING ON ITS SIDE
Answer:
The ruins of the day
Painted with a scar
And the more I straighten out
The less it wants to try
The feelings start to rot
One wink at a time
Oh oh
Forgiving who you are
For what you stand to gain
Just know that if you hide
It doesn't go away
When you get out of bed
Don't end up stranded
Horrified with each stone
On the stage
My little dark age
Picking through the cards
Knowing what's nearby
The carvings on the face
Say they find it hard
And the engine's failed again
All limits of disguise
The humor's not the same
Coming from denial
Oh oh
I grieve in stereo
The stereo sounds strange
I know that if you hide
It doesn't go away
If you get out of bed
And find me standing all alone
Open-eyed
Burn the page
My little dark age
I grieve in stereo
The stereo sounds strange
You know that if it hides
It doesn't go away
If I get out of bed
You'll see me standing all alone
Horrified
On the stage
My little dark age
Giddy with delight
Seeing what's to come
The image of the dead
Dead ends in my mind
Policemen swear to God
Love's seeping from the guns
I know my friends and I
Would probably turn and run
If you get out of bed
Come find us heading for the bridge
Bring a stone
All the rage
My little dark age
I grieve in stereo
The stereo sounds strange
I know that if you hide
It doesn't go away
If you get out of bed
And find me standing all alone
Open-eyed
Burn the page
My little dark age
All alone
Open-eyed
Burn the page
My little dark age

Find the first five terms of the recursive sequence.
Answer:
The first five terms of the recursive sequence are;
5, 12, 19, 26, 33
Step-by-step explanation:
The given sequence is presented as follows;
aₓ = a₍ₓ ₋ ₁₎ + 7
The first term of the sequence, a₁ = 5
Therefore, we have;
a₂ = a₍₂ ₋ ₁₎ + 7 = a₁ + 7 = 5 + 7 = 12
a₃ = a₍₃ ₋ ₁₎ + 7 = a₂ + 7 = 12 + 7 = 19
a₄ = a₍₄ ₋ ₁₎ + 7 = a₃ + 7 = 19 + 7 = 26
a₅ = a₍₅ ₋ ₁₎ + 7 = a₄ + 7 = 26 + 7 = 33
The first five terms of the recursive sequence are therefore;
5, 12, 19, 26, 33.

Answer:
x = 15
Step-by-step explanation:
One side length, 49 ft, is given. The opposite side is equal to this. So solve (5x - 26) = 49. Add 49 + 26 to get 75. Then divide 75 by 5 to get 15.

What angle relationship best describes angles AFC and DFB?
A) Adjacent angles
B) Complementary angles
C) Linear pairs
D) Vertical angles
Answer:
Vertical Angles
Step-by-step
I believe this is the case because since the angles intercept in order to form also it's the only answer that has to do with intercepting from what we can see from the diagram.
There are different types of relationships between angles including alternate, corresponding, vertical, adjacent, complementary and supplementary angles
The correct option for the relationship that best describes angles AFC and DFB is option D;
D) Vertical angles
The reason the chosen option is correct is as follows;
The given diagram shows line EF perpendicular to line AB and line CD crosses line AB at point F
Therefore, the angles ∠AFC and ∠DFB formed by lines AB and CD with their orientation in the order of their names are opposite to each other and other are known as vertical angles

Anna&katie together have $60.Anna has $9 more than twice Katie's amount how much money does each have? Write a system and use substitution to solve
Answer:
Ana had $17 and Katie had $43.
Step-by-step explanation:
Since Ana and Katie together have $60, you can express this as follows:
x+y=60, where:
x is the amount that Ana has
y is the amount that Katie has
Also, Anna has $9 more than twice Katie's amount, which can be expressed as:
x=2y+9
The system is:
x+y=60 (1)
x=2y+9 (2)
Now, you can replace (2) in (1) and solve for y:
2y+9+y=60
3y=60-9
3y=51
y=51/3
y=17
Finally, you can replace the value of y in (2) to find x:
x=2(17)+9
y=34+9
y=43
According to this, the answer is that Ana had $17 and Katie had $43.

Eudora ran from her home to her secret laboratory at an average speed of 12\text{ km/h}12 km/h12, start text, space, k, m, slash, h, end text. She then took one of her jetpacks and flew to her school at an average speed of 76\text{ km/h}76 km/h76, start text, space, k, m, slash, h, end text. Eudora traveled a total distance of 120120120 kilometers, and the entire trip took 222 hours. How long did Eudora spend running, and how long did she spend flying using her jetpack? Eudora ran for hours and flew for hours using her jetpack.
Answer:
Eudora spent 0.5 hours from home to library and 1.5 hours from library to school
Step-by-step explanation:
Given
Home to Library:
[tex]S_1 = 12km/h[/tex] -- Average Speed
Library to School
[tex]S_2 = 76km/h[/tex] -- Average Speed
Total
[tex]Distance = 120km[/tex]
[tex]Time = 2\ hr[/tex]
Required
Determine the time taken from home to library and from library to school
Let the time spent from home to library be x. So, from library to school will be: 2 - x
So, we have:
Home to Library:
[tex]S_1 = 12km/h[/tex] -- Average Speed
[tex]T_1 =x[/tex] -- Time
Library to School
[tex]S_2 = 76km/h[/tex] -- Average Speed
[tex]T_2 =2 - x[/tex] -- Time
Distance is calculated as:
[tex]Distance = Speed * Time[/tex]
Home to Library:
[tex]D_1 = S_1 * T_1[/tex]
[tex]D_1 = 12 * x[/tex]
[tex]D_1 = 12x[/tex]
Library to School:
[tex]D_2 = S_2 * T_2[/tex]
[tex]D_2 = 76 * (2- x)[/tex]
[tex]D_2 = 152- 76x[/tex]
The total distance is 120km. So, we have:
[tex]120km = D_1 + D_2[/tex]
[tex]120 = 12x + 152 - 76x[/tex]
Collect Like Terms
[tex]120 - 152 = 12x - 76x[/tex]
[tex]-32 = -64x[/tex]
[tex]-64x=-32[/tex]
Solve for x
[tex]x = \frac{-32}{-64}[/tex]
[tex]x = 0.5[/tex]
Recall that:
[tex]T_1 =x[/tex]
[tex]T_2 = 2 - x[/tex]
So, we have:
[tex]T_1 = 0.5[/tex]
[tex]T_2 = 2 -0.5 = 1.5[/tex]

2X=20

x=80
largest angle is 80
Step-by-step explanation:
plz make me brainliest
Answer:
80°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the parts of the ratio, 2 + 3 + 4 = 9 parts
Divide 180° by 9 to find the value of one part of the ratio
180° ÷ 9 = 20° ← value of 1 part of ratio, then
2 parts = 2 × 20° = 40°
3 parts = 3 × 20° = 60°
4 parts = 4 × 20° = 80°
The measure of the largest angle is 80°
