(1) 5 years ago a man's age was 5 times the age of his daughter's. 3 years hence, twice
his
age will be equal to 6 times his daughter's age. Find their present ages.
Answer: Daughter = 13, Man = 45
Step-by-step explanation:
Today 5 yrs ago 3 years hence (future)
Man x x - 5 x + 3
Daughter y y - 5 y + 3
5 years ago a man's age was 5 times the age of his daughter's
EQ1: x - 5 = 5(y - 5) → x - 5 = 5y - 25 → x - 5y = -20
3 years hence, twice the man's age will be equal to 6 times his daughter's age.
EQ2: 2(x + 3) = 6(y + 3) → 2x + 6 = 6y + 18 → 2x - 6y = 12
Solve the system of equations using the Elimination method:
EQ1: x - 5y = -20 → -2(x - 5y = -20) → -2x + 10y = 40
EQ2: 2x - 6y = 12 → 1(2x - 6y = 12) → 2x - 6y = 12
4y = 52
÷4 ÷4
y = 13
Substitute y = 13 into either equation to solve for x:
EQ1: x - 5y = -20
x = 5y - 20
x = 5(13) - 20
x = 65 - 20
x = 45

Answer: f(-5)= 7
Step-by-step explanation:
The x value is -5 so look for the y value of the x value which is 7
Answer:
f(-5) = 7
Step-by-step explanation:
f(x) is referring to the y value, so what it is equal to would be the x value at that spot
in this case the y value is -5 so the x value is 7
In the diagram below, all measurements are given correct to the nearest cm. Calculate the greatest possible area of the shaded region.
The possible area of the region that is shaded is given as 462cm.
How to solve for the area of the shaded regionThe picture here shows us two rectangles.
The area of a rectangle is given as L * w
= length x width
We have to find the area of the first rectangle
21cm x 42cm
= 882 cm
Next we find the area of the rectangle inside
15cm x 28cm
= 420
To get the area of the shaded region
= 882 - 420
= 462cm

17 more than the quotient of a number and 4
Answer:
x ÷ 4 + 17
Step-by-step explanation:
17 more than the quotient of a number and 4. You're adding 17 to the quotient of x and 4, or x divided by 4.
The expression "17 more than the quotient of a number and 4" can be written as:
(x / 4) + 17
In this expression, x represents the unknown number. We divide x by 4 to find the quotient of the number and 4, and then add 17 to it.
For example, if we substitute x = 12 into the expression, we would have:
(12 / 4) + 17 = 3 + 17 = 20
Therefore, the value of the expression "17 more than the quotient of a number and 4" depends on the specific value of x that is substituted into the expression.

At the beginning of the business day, a bank's vault held $575,900. By the end of the day, $(3.5 103) had been added to the vault. How much money did the banks vault hold at the end of the business day write ur answer in standard form
3.5*10^3=3,500
3,500+ 575,900=579,400
The bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.
What are integers?An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Now it is given that,
Money in the bank vault at the beginning of the day = $575,900
Money added in the vault at the end of the day = $3.5 x 10^3 = $3,500
Since money is added in the vault thus it is gain.
So, Money added in the vault at the end of the day = + $3,500
Thus, Money at the end of the business day = $575,900 + $3,500 = $579,400
Thus, the bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.

Solve the equation for n
3(n-5) = -21
Answer:
n=−2
Step-by-step explanation:
Let's solve your equation step-by-step.
3(n−5)=−21
Step 1: Simplify both sides of the equation.
3(n−5)=−21
(3)(n)+(3)(−5)=−21(Distribute)
3n+−15=−21
3n−15=−21
Step 2: Add 15 to both sides.
3n−15+15=−21+15
3n=−6
Step 3: Divide both sides by 3.
Answer: n= -2
Step-by-step explanation:
3(n−5)=−21
Divide both sides by 3.
n−5=
3
−21
Divide −21 by 3 to get −7.
n−5=−7
Add 5 to both sides.
n=−7+5
Add −7 and 5 to get −2.
