If Amy, Ravi, and Bob have a total of $127 in their wallets. Bob has 4 times what Ravi has. Ravi has $7 less than Amy. The amount they have have in their wallets is : Army has $22.33, Ravi $89.33, Henry $15.33.
How to determine wallet amount?Let Army represent x dollars
Let Ravi represent 4x
Let Bob represent x - 7
Hence,
x + x - 7 + 4x = 127
Simplify by combining like terms
6x - 7 = 127
Add 7 to both sides of the equation leaving 6x
6x = 127+7
6x = 134
x =134/6
x = 22.33
x = Army has $22.33
Ravi
4x where x = 22.33
4(22.33) = 89.33
Bob
x - 7 where x = 22.33
22.33 -7 = 15.33
Prove :
Ravi + Bob + Henry = 127
= 22.33 +89.33 + 15.33 = 126.99 ≅127 (Approximately)
Therefore the have $22.23, $89.33 and 15.33 respectively.

You are creating identical candy bags using 36 chocolate bars and 81 caramel bars. what is the greatest number of bags you can fill using all the candy?
The greatest number of bags that can be filled using all the candy is 9.
The greatest number of bags that can be filled using all the candy can be determined by calculating the greatest common factor (GCF).
The greatest common factor of two or more numbers is a term used in mathematics that can be described as the greatest number among all the common factors of these numbers. If x and y are two numbers, GCF is the largest number that divides both x and y without leaving any remainder.
As there are 36 chocolate bars and 81 caramel bars, therefore we determine the GCF of 36 and 81;
The common factors of 36 and 81 are found to be: 1, 3 and 9
Hence the greatest common factor (GCF) out of these is 9.
Therefore the greatest number of bags that can be filled using all the candy is calculated to be 9

Answer:
3x + 8y = - 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
8x - 3y = - 4 ( subtract 8x from both sides )
- 3y = - 8x - 4 ( divide through by - 3 )
y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{4}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{8}{3}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{8}{3} }[/tex] = - [tex]\frac{3}{8}[/tex] , then
y = - [tex]\frac{3}{8}[/tex] x + c ← is the partial equation of the perpendicular line
to find c substitute (- 8, 2 ) into the partial equation
2 = 3 + c ⇒ c = 2 - 3 = - 1
y = - [tex]\frac{3}{8}[/tex] x - 1 ← equation of perpendicular line in slope- intercept form
multiply through by 8 to clear the fraction
8y = - 3x - 8 ( add 3x to both sides )
3x + 8y = - 8 ← equation of perpendicular line in standard form

Oil
Salt
b) what is the total amount of salt use by both factories?

Factory A uses more oil by 2.05×10⁵ lbs, total salt used is 4.805×10⁵ lbs and total ingredients used in factory A are 57.18×10⁵ lbs.
a) The oil used by Factory A = 5.61×10⁵ lbs
The oil used by Factory B = 3,56,000 lbs
The oil used by Factory B = 3.56×10⁵ lbs
Comparing the coefficient. Since 5.61 is greater than 3.56, the factory A used more oil. Difference in amount = 5.61×10⁵ - 3.56×10⁵
Difference in amount = 2.05×10⁵ lbs
b) Salt used by Factory A = 2.87×10⁵ lbs
Salt used by Factory B = 193,500 lbs
Salt used by Factory B = 1.935×10⁵ lbs
Total salt used by both the factories = 2.87×10⁵ + 1.935×10⁵ lbs
Total salt used by both the factories = 4.805×10⁵ lbs
c) Potato used by Factory A = 4.87×10⁶ lbs
Potato used by Factory A = 48.7×10⁵lbs
Oil used by Factory A = 5.61×10⁵ lbs

Total ingredients used in Factory A = 48.7×10⁵ + 5.61×10⁵ + 2.87×10⁵ lbs
Total ingredients used in Factory A = 57.18×10⁵ lbs
2.05×10⁵ lbs more oil is used by Factory A, 4.805×10⁵ lbs is the total amount of salt used and 57.18×10⁵ lbs ingredients are used in factory A.

Not sure how to find the area of this shape. Please help asap
Answer:
6.75m^2
Step-by-step explanation:
The shape is made up of a trapezoid on top and a rectangle on the bottom.
The rectangle's area is easier, so first:
Area_rectangle
= length × width
= 2.5 × .5
= 1.25 m^2
For area of a trapezoid, you need three measures: both bases and the height.
One base is 3m. The other base is the top side of the rectangle, so it is 2.5m.
The height is
2.5 - .5
because the height of the trapezoid is not including the rectangle, so take away .5
Trapezoid's height is 2.5 - .5 is 2.
Area_trapezoid
= 1/2 (base+base)height
= 1/2 (3+2.5)2
=5.5
Area_total
= Trapezoid+rectangle
= 5.5 + 1.25
=6.75m^2
The total area is 6.75square meters.

The transformation of the graph y = (x - 2)² to the graph of y=x²-3 is 2 units left and 3 units down therefore, option (B) is correct.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
As per the given graph y = (x - 2)²
A function will shift a unit left for x → x + a and b units down if y → y - b.
Replace x → x + 2 and y → y - 3
y = (x + 2 - 2)² - 3
y = x² - 3
Therefore, the transformation of the graph y = (x - 2)² to the graph of y=x²-3 is 2 units left and 3 units down".
