Answer:
A) x + y = 24 and 16x + 20y = 434
B) Item A = 11.5 hours per day
Item B = 12.5 hours per day
C) The work done in part A was to derive a system of equations based on the values given to us to produce the items where x and y denoted the number of hours per day it took to make item A and B respectively. Meanwhile, in part B, I employed the substitution method to solve the simultaneous equation derived in part A in order to get the number of hours per day used for each item.
Step-by-step explanation:
A) Let x represent the amount of hours it took to make item A and let y represent the amount of hours it took to make item B.
Thus, since the machine runs 24 hours a day, we have;
x + y = 24 - - - (eq 1)
Since the plant can make 16 of Item A and 20 of Item B per hour and it made 434 items yesterday, we have;
16x + 20y = 434 - - - (eq 2)
B) to find the time taken for each item per day, let's make x the subject in eq 1.
x = 24 - y
Put 24 - y for x in eq 2;
16(24 - y) + 20y = 434
384 - 16y + 20y = 434
4y = 434 - 384
4y = 50
y = 50/4
y = 12.5 hours
Thus, x = 24 - 12.5
x = 11.5 hours
C) The work done in part A was to derive a system of equations based on the values given to us to produce the items where x and y denoted the number of hours per day it took to make item A and B respectively. Meanwhile, in part B, I employed the substitution method to solve the simultaneous equation derived in part A in order to get the number of hours per day used for each item.
Charles lost 4 of the 10 dollar bills that his parents gave him for his birthday. What percentage of his dollar bills did he lose?
Answer:
40
Step-by-step explanation:
Answer:
40% because there are 10 all together which would make the percentage 100% and if you were to take 1 away it would go down to 90% and so on

Evaluate: log6 1,296
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex] then
let [tex]log_{6}[/tex] 1296 = n
1296 = [tex]6^{n}[/tex] = [tex]6^{4}[/tex] , thus
n = 4

Answer:
m=s+0.50
3m+2s=23.95
Step-by-step explanation:
Answer:
m-s+0.50
3m+2s=23.95
Step-by-step explanation:
the first one is defining m in terms of S
the second is solving
I know they didn't ask but here is the solution:
so in this case you would replace 3m with 3(s+0.50)
The area of square C is 100 square units and the area of square B is 64 square units. What would be the area of square A?
Answer: The area of square A is 28 square units because the area is decreasing by 36 and the angles on each side is decreasing by 9
Step-by-step explanation:
100 divide by 4 sides = 25
64 divide by 4 sides = 16
28 divide by 4 sides = 7
Evaluate 1/5t + 1/10 when t= 1/2

[tex] \frac{1}{5} ( \frac{1}{2} ) + ( \frac{1}{10} ) \\ \frac{1}{10} + \frac{1}{10} \\ = \frac{2}{10} \\ = \frac{1}{5} [/tex]
Use the Distributive Property to solve the equation.
- 4(x + 2) = 24
Apply the Distributive Property and simplify.
- 4(x + 2) = 24
- 4x + _ = 24
What goes in between -4x+ and =24
Answer:
-8
Step-by-step explanation:
First multiple the x by -4 giving -4x then multiply the same -4 by 2 giving -8
Given the equation x+y=20 and x-y=8,which values of x and y satisfy both equations

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.
Answer:
x = 12Side = 23 unitsStep-by-step explanation:
STU is an equilateral triangle. And:
ST = 2x - 1SU = 5x - 37TU = x + 11All sides are equal. Then take one pair and solve for x:
2x - 1 = 5x - 373x = 36x = 12Substitute x to find the side length:
2x - 1 = 5x - 37 = x + 11 = 23Ralph’s annual income is about $32,000. Based on his expenses illustrated in the graph below, roughly how much should Ralph expect to pay in taxes this year?

Solve for n. -4n + 7 = 1 – 2n
Answer:
n = 3
Step-by-step explanation:
subtract 1 from both sides to get:
-4n + 6 = -2n
then add 4n to both sides to get:
6 = 2n
then divide both sides by 2 to get:
3 = n
