Answer:
Father age= 52 years
Son age =8 years
Step-by-step explanation:
Given:
⇒ Sum of ages of father and his son = 60 years
⇒ After 14 years - father's age will be 3 times the age of his Son
⇒ Find their present ages
Solution:
According to the given,
The total = 60
Father age = "x " ( unknown)
Son age = 60 - x
In additionally,
Father age = ( x + 14 ) years
Son age = ( 60 - x + 14 )
= ( 74 - x ) years
Setting up the problem:
x + 14 = 3 ( 74 - x )
Removing parentheses:
x + 14 = 3 × 74 - x
Multiply:
x + 14 = 222 - 3x
variable on one side and the other on other side:
x + 3x = 222 - 14
Add/Subtract:
4x = 208
Divide:
4x/4 = 208/4
x = 52
Hence, at present:
Father age = 52
Son age = 60 - 52
→ 8
As a result,
Their present ages:
Father = 52
Son = 8

If a dozen eggs cost $1.35 what I sent the unit cost, plz explain how to get the answer along with the answer
Plz don’t waste my points
Answer:
0.1125
Step-by-step explanation:
1.35 divided by 12 = 0.1125
Answer:
$0.11 per egg
Step-by-step explanation:
unit cost means how much each one costs
there are 12 eggs in a dozen
so all you have to do is divide $1.35 by 12
which equals $0.1125
but money is only counted by the hundredths place so we have to round
and that would be $0.11
hope this helps and plz mark brainliest :D
James needs to buy shirts for his business. Company C charges customers a one-time $50 printing fee plus $10 for every shirt. Company D charges a one-time $20 printing fee plus $15 for every shirt. Which inequality can be used to find s, the minimum number of shirts that can be purchased so that the total charge at Company C is less than the total charge at Company D? 50s+10>20s+15 50s+10 20+15s
Answer:
50 + 10s > 20 + 15s
Step-by-step explanation:
This is the answer because if James pays for 1 shirt from company C he would be paying $60, but if he were to pay for 1 shirt at company D he would be paying $35. So that's why its >. Anyway, the s goes on the second number because that's the price for every shirt, And the first number is by itself because its a one-time printing fee.

Answer:
17.3%
Step-by-step explanation:
The rate of return is the net profit divided by the purchase price.
The purchase price was ...
(20 share) × ($30/share) = $600
The net proceeds from the sale were ...
proceeds = selling price - commission
= $710 -$6 = $704
So, the net profit is ...
profit = $704 -600 = $104
And the rate of return is ...
profit / investment = $104/$600 = 17.3%

Answer: The measure of angle 3 is 50 degrees.
Step-by-step explanation:
We know that angle 2 is 130 degrees.
Angle 1 and angle 2 are verticle angles which means that they are across and equal to each other.
So angle 1 and angle 2 are 130 degrees.
Add up both angle 1 and angle 2, 130 + 130 = 260.
Now, all of these angles add up to be 360 degrees in total as they make a circle and there are 360 degrees in one.
Subtract 260 from 360, 360 - 260 = 100.
Since both angle 3 and angle 4 are also verticle angles we need to split the 100 degrees evenly, 100 ÷ 2 = 50.
So, angle 3 is 50 degrees.

Nancy's morning routine involves getting dressed, eating breakfast, making her bed, and driving to work. Nancy spends ⅓ of the total time in the morning getting dressed, 10 minutes eating breakfast, 5 minutes making her bed, and the remaining time driving to work. If Nancy spends 35 ½ minutes getting dressed, eating breakfast, and making her bed, how long is her drive to work?
Answer: 26 minutes
Step-by-step explanation:
Assume that the total time spent in the morning which includes getting dressed, eating breakfast, making her bed, and driving to work is x.
Time getting dressed = ¹/₃x
Eating breakfast = 10 mins
Making bed = 5 mins
¹/₃x + 10 + 5 = 35 ½
¹/₃x + 15 = 35 ½
¹/₃x = 35 ½ - 15
¹/₃x = 20 ½
x = 20 ½ / ¹/₃
= 61.5 minutes
Total morning routine is is 61.5 mins
Time taken to drive to work is;
= 61.5 - 35 ½
= 26 minutes

Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (1, 5).
Answer:
4x-y+1=0
Step-by-step explanation:
here,given equation of a line id
4x-y-2=0.. eqn(i)
equation of any line parallel to line (i) is
4x-y+k=0...eqn(ii)
since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]
4*1-5+k=0
or, 4-5+k=0
or,-1+k=0
•°•k=1
substituting the value of k=1 in eqn(ii),
4x-y+1=0 is the required equation of the line.

Sasha has $850 to deposit into two accounts.
Sasha will deposit $450 at First Oak Bank.
She will deposit the rest at River Point Bank.
Sasha will not make additional deposits or withdrawals.
How much more money will be in her account at First Oak Bank than at River Point after 2 years?
Amount in First Oak Bank is $87.84 than at River Point after 2 years.
What is Simple Interest and Compound Interest?Simple interest is the interest obtained over the principal amount on a certain rate.
Compound interest is the amount of interest which is calculated on the principal amount as well as the amount accumulated over the previous period.
First oak bank is simple with 6% interest.
Final amount in simple interest, A = P(1 + rt), where P is the principal amount , r is the interest rate and t is the number of years.
A = 450 (1 + (0.06 × 2)) = $504
River point bank is 2% compounded annually
Final amount in compound interest, A = P(1 + r/n)^(nt), where, P is the principal amount, r is the interest rate, t is the number of years and n is the number of times interest compounded annually.
P = 850 - 450 = 400
n = 1, since compounding is only 1 time in a year
A = 400(1 + 0.02)² = $416.16
Amount which is more in First oak is $504 - $416.16 = $87.84
Hence the amount more in the First oak account is $87.84.

Ms. Barcht Open a savings account with $50 and deposit $25 every week. Mrs. Greene save $75 every week. How many weeks will Mrs. Greene have more money in her account than ms. Bracht?
A. 25x+75>50
B. 75x=25x+50
C. 75x>25x+50
D. 75x<25x+50
Answer:
C
Step-by-step explanation:
Ms. Barcht's savings account can be modeled with the expression
50 + 25x
Mrs. Greene's savings account can be modeled with the expression
75x
Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.
Mrs.Greene > Ms. Bracht
75x > 25x + 50
Answer:
The answer would be C. 75x>25x+50
Step-by-step explanation:
The answer would be C. because Ms. Barcht started with $50 and deposits $25 every week while Mrs. Greene saves $75 a week. 7 days is a week so lets multiply $25 x 2 (2 weeks). Ms. Barcht would have $100 by the end of 2 weeks and Mrs. Greene would have $150 by the end of 2 weeks because $75x2 is $150
Hope this helps.
