angle ABE is equivalent
to the whole angle, and it measures 2b.
while the angle ABF is only a portion of angle ABE, and it
measure 7b - 24.
since we know the measure of the whole angle and a part of
the angle, we can then subtract to find the left over angle (angle EBF), so
Angle EBF = Angle ABE - Angle ABF
Angle EBF = 2b – (7b – 24)
Angle EBF = 24 – 5b
weight A weighs 50 pounds. weight B weighs 100 pounds. if A is placed 6 feet from the pivot, how far must B be placed from the pivot in order for the bar to achieve balance?
To achieve balance, the momentum on both sides must be equal so that it cancels out. Momentum is simply the product of mass and distance, therefore:
50 pounds * 6 ft = 100 pounds * X
X = 3 ft
Hence B must be placed 3 ft from the pivot.

Emelina wrote the equation of a line in point-slope form as shown below. (y+4)=3(x+2) What is Emelina’s equation in slope-intercept form?
Answer:
[tex]y=3x+2[/tex]
Step-by-step explanation:
We are given equation as
[tex](y+4)=3(x+2)[/tex]
Since, we have to write equation in slope-intercept form
so, we can use slope-intercept formula
[tex]y=mx+b[/tex]
where m is a slope
b is y-intercept
so, we can write our equation in this form
[tex](y+4)=3(x+2)[/tex]
Distribute 3
[tex]y+4=3\times x+3\times 2[/tex]
[tex]y+4=3x+6[/tex]
Subtract both sides by 4
[tex]y+4-4=3x+6-4[/tex]
[tex]y+4-4=3x+6-4[/tex]
[tex]y=3x+2[/tex]
So, slope-intercept form of equation is
[tex]y=3x+2[/tex]

My clock is 75 inches tall and 28 in wide .What is the ratio of height to wide in fraction form
The ratio of height to wide in the fraction form of the clock is 75/28.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Height of clock = 75 inches.
Width of clock = 28 inches.
The ratio of height to width = Height of clock / Width of clock
So,
The ratio of height to width = = 75/28.
Hence "The ratio of height to wide in the fraction form of the clock is 75/28".

Which angle pairs are supplementary? Check all that apply
The sum of two angles is equal to [tex]180^\circ[/tex] than the angle pairs are known as supplementary angles. Therefore, from the given diagram angle pairs [tex]\rm \angle 3\;and\;\angle6[/tex], [tex]\rm \angle 5\;and\;\angle6[/tex], [tex]\rm \angle 4\;and\;\angle5[/tex], [tex]\rm \angle 3\;and\;\angle4[/tex] and [tex]\rm \angle 7\;and\;\angle 8[/tex] are supplementary angles. So, the correct options are: B), C), and E).
Given :
[tex]\angle 3 = 90^\circ[/tex]
The sum of two angles is equal to [tex]180^\circ[/tex] than the angle pairs are known as supplementary angles.
From the diagram given in the question it can be clearly observe that if [tex]\angle 3 = 90^\circ[/tex] than [tex]\rm \angle 4,\;\angle 5,\;and\;\angle 6[/tex] are also equal to [tex]90^\circ[/tex].
Than according to the definition of supplementary angles:
[tex]\angle 3 +\angle6 = 180^\circ[/tex]
[tex]\angle 3 +\angle4 = 180^\circ[/tex]
[tex]\angle 4 +\angle5 = 180^\circ[/tex]
[tex]\angle 5 +\angle6 = 180^\circ[/tex]
[tex]\angle 7 +\angle8 = 180^\circ[/tex]
Therefore, angle pairs [tex]\rm \angle 3\;and\;\angle6[/tex], [tex]\rm \angle 5\;and\;\angle6[/tex], [tex]\rm \angle 4\;and\;\angle5[/tex], [tex]\rm \angle 3\;and\;\angle4[/tex] and [tex]\rm \angle 7\;and\;\angle 8[/tex] are supplementary angles.

If mary ellen invest x dollars at 5%, write an equation that describes the total interest
For a one-year investment, the equation is I = x imes 0.05 imes 1.
If Mary Ellen invests x dollars at an interest rate of 5%, we can write an equation that describes the total interest earned on that investment using the simple interest formula. The formula for calculating simple interest is Interest = Principal imes Rate imes Time. Assuming the investment is for 1 year, the equation for the total interest (I) Mary earns would be:
I = x imes 0.05 imes 1
This equation states that the interest Mary earns is equal to the amount of money she invested (x dollars) multiplied by the interest rate (5% or 0.05 as a decimal) and the time the money is invested (1 year).
If Mary Ellen invests $100, the total interest she would earn in one year at a 5% interest rate would be calculated as follows:
I = $100 imes 0.05 imes 1 = $5
