Answer:
b 1/4 (n-64)
Step-by-step explanation:
Multiplying the expression by 1 does not change its value:
= (1/4)(4) × (1/4n -16)
= (1/4) × (4(1/4n -16)) . . . . . associative property
= (1/4) × ((4/4)n -4·16) . . . . distributive property
= (1/4)(n -64) . . . . matches choice B

(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

I REALLY NEED HELPPPPP!! Write a paragraph proof for the following conjecture:
Given: m∠ 1 + m∠ 2 = m∠ 4
Prove: m∠3 + m∠1 + m∠2 = 180
Answer:
Given: measure 1 + measure 2 = measure 4
measure 4 + measure 3 must be 180 degrees because they are supplementary
If measure 4 + measure 3 is 180, and measure 1 + measure 2 = measure 4, we can substitute measure 4 in the first equation for measure 1 + measure 2.
Therefore, we arrive at the answer measure 1 + measure 2 + measure 3 = 180.
I really hoped this helped, and if it did, please consider giving me brainliest.

Find the value of x.
Area of rectangle = 36
▅ х
x + 5
The value of x is 4, which is determined by the quadratic equation.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The rectangle of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that area of the rectangle = 36
Area of rectangle = width of the rectangle × length of the rectangle
Here the width of the rectangle = x
And length of the rectangle = x + 5
The rectangle of a rectangle = x × (x + 5)
36 = x² + 5x
x² + 5x - 36 = 0
x² + 9x - 4x - 36 = 0
(x + 9)(x - 4) = 0
x = -9 and x = 4
Take the value of x = 4 and the negative value is neglected because the dimension can't be negative.
Therefore, the value of x is 4.

Surveyors wished to know the distance across a lake between A and B. They measured the distance from B to C as 100 m and the angle from C to A to be 55°. Knowing that the angle between CB and BA was 90°, they used trig to solve for the distance. Show how it was done
Answer:
AB ≈ 70mStep-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m

22.40 x
Using cross products
14x = 22.40 * 12
14x =268.8
Divide each side by 14
14x/14 = 268.8/14
x =19.20

If two parallel lines are cut by a transversal, then corresponding angles are congruent.
B.
If two parallel lines are cut by a transversal, then complementary angles are congruent.
C.
If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
D.
If two parallel lines are cut by a transversal, then alternate exterior angles are congruent.
Answer: C
Step-by-step explanation:
The pair of angles created on the inner side of the parallel lines intersected by a transversal but on opposing sides of the transversal is known as an alternative interior angle. The correct option is C.
What are Alternate Interior angles?When two parallel lines are intersected by a transversal, the pair of angles created on the inner side of the parallel lines but on opposing sides of the transversal is known as an alternative interior angle. These angles are always equal in measure.
The best statements BEST that proves ∠XWY ≌ ∠ZYW is that If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
Hence, the correct option is C.

assume that a varies directly as b. when the value of a is 5 the value of b is 18. when the value of a is 22 what is the value of b?
Answer:
The value of b when a is 22 is 79 1/5
Step-by-step explanation:
a varies directly as b
Let k be the constant of proportionality;
then;
a = kb
5 = k * 18
k = 5/18
Finding the value of b, when a is 22
22 = 5/18 * b
5b = 18 * 22
b = (18 * 22)/5 = 79 1/5

What is the value of r for 19 and 20?
Answer:
19.) r = -4 20.) r = 1
Step-by-step explanation:
19.) Because we know the slope and have some points, we can use point-slope form to find the equation.
Point-slope form is:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - 3 = 7/6(x - 1)
y - 3 = 7/6x -7/6
y = 7/6x + 11/6
Now that we know the equation, we can put in the x value to find the y (In this case, y = r):
r = 7/6(-5) + 11/6
r = -35/6 + 11/6
r = -4
20.) Because the slope is undefined, that means on the graph, the line will appear straight and vertical. This means the equation will be something like x = a number.
We have the point (1,4). Since we know that the x value will never change, we know that r will have to equal 1 as well.
r = 1
What is the slope of the line on the graph?

Step-by-step explanation:
The points I will be using are (-3, 6) and (0,0).
To find the slope, you sub these points into the slope formula - rise over run.

Step-by-step explanation:
to get from (0,0) to (-3,6) you rise 6 and go left 3. Then 6÷-3= -2.
