3 goes into 20 six times with a remainder of 2.
To determine how many times 3 goes into 20, we can perform division.
Dividing 20 by 3 gives us:
20 ÷ 3 = 6 with a remainder of 2
Or, 3 | 20 | 6

Conray is 72 years old. He is three times his daughter's age. His daughter is three years younger than Nia.
How old is Nia?
1️⃣0️⃣‼ POINTS!!!
Answer: 27 I think
Step-by-step explanation:
72 divided by 3 plus 3
The age of Nia is given by the equation N = 27 years old
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the age of Nia be represented as N
Now , the equation will be
Let the age of Conray be C
The value of C = 72 years
And , Conray is three times his daughter's age
Let the age of Conray's daughter be D
The value of D = C / 3
Substituting the values in the equation , we get
The value of D = 72/3 = 24 years
And , Conray's daughter is three years younger than Nia
So , N = D + 3
Substituting the values in the equation , we get
N = 24 + 3
On simplifying the equation , we get
N = 27 years
Therefore , the value of N is 27 years
Hence , the age of Nia is 27 years

Answer:
Part A: C) The order of discounts does not matter.
Part B: both prices are $54.91
Step-by-step explanation:
Part A:
The calculation of the final price can be ...
((original price)·(1 - membership discount))·(1 -sale discount)
= ((original price)(0.88))(0.80)
The associative and commutative properties of multiplication tell you this is fully equivalent to ...
= (original price)(0.80)(0.88)
In short, the order of discounts does not matter.
__
Part B:
When the membership discount is applied first, the final price is ...
($78)(0.88)×0.80 = $68.64·0.80 = $54.91
When the sale discount is applied first, the final price is ...
($78)(0.80)×0.88 = $62.40·0.88 = $54.91

One side of a rectangle is three yards longer than twice the length of the other side. If the perimeter is 27 yards, what is the length of the other side? Please help I'll give brainliest
Answer:
Length of sides ;
3.5 yards ; 10 yards.
Step-by-step explanation:
Let :
Side 1 = x
Side 2 = y
x = 2y + 3
Perimeter (P) of rectangle = 2(side1 + side2)
Perimeter, P = 27
P = 2(x + y)
27 = 2(2y + 3 + y)
27 = 2(3y + 3)
27 = 6y + 6
27 - 6 = 6y
21 = 6y
y = 21/6
y = 3.5
From ; x = 2y + 3
x = 2(3.5) + 3
x = 7 + 3
x = 10
Length of the other side of the rectangle will be 10 yards.
Perimeter of a quadrilateral:Perimeter of a quadrilateral is given by sum of all the sides.
Perimeter of a rectangle = 2(Length + Width)
Given in the question,
One side of the rectangle is three yards longer than twice of the other side.Perimeter of the rectangle = 27 yardsLet one side of the rectangle = x yards
Therefore, other side of the rectangle = (2x + 3) yards
Substitute the values in the expression for the perimeter,
Perimeter = 2[x + (2x + 3)]
27 = 2(3x + 3) [Simplify the equation]
27 = 6x + 6
6x = 21
x = 3.5 yards
Other side of the rectangle = (2x + 3) yards
= 2(3.5) + 3
= 10 yards
Therefore, length of the other side of the rectangle will be 10 yards.

Answer:
3
Step-by-step explanation:
j(2) means that x equals 2...
the first inequality in the function says that x is greater than or equal to 2
the second inequality states that x is greater than 2(not equal to) and is less than or equal to 5
the third one states that x is greater than 5
x applies to the first inequality since we know that x can be equal to 2
Now, to the number before the if
there is a 3 before the if in the first inequality
This means that if x is greater than or equal to 2 the y or the function would equal 3
therefore, j(2) would equal 3

month The car cost a total of $17,860. Write an equation to
represent this scenario.
Answer:
256x +2.500=17860
Step-by-step explanation:
So she has to pay 256 per month which means every month.So that is our reapeted fee.Because it is reapeting every month.2.500 is the fee that you have to give for down time payement but only once .So that is our One Time Fee.And 17860 is our total.Always remember that the vairable goes with the reapted fee.and our equation is reapted fee times vairaible addes to one time fee is equal to total.

The distance a coiled spring stretches varies directly with the amount of weight hanging on the spring. If a spring stretches 2 cm when a 30 gram weight is hung from it, how far will it stretch when a 75 gram weight is hung from the spring?
Answer:
5 cm
Step-by-step explanation:
The distance a coiled spring stretches varies directly with the amount of weight hanging on the spring.
Distance = D
Weight = W
Hence:
D ∝ W
D = kW
Where k is constant of proportionality
Step 1
We solve for k
If a spring stretches 2 cm when a 30 gram weight is hung from it.
2 = 30k
k = 2/30
k = 1/15
Step 2
how far will it stretch when a 75 gram weight is hung from the spring?
D = kW
We are solving for D
k = 1/15
D = 1/15 × 75
D = 5 cm
The spring would stretch 5cm with a weight of 75 gram.
