the cost of 5 books and 4 pens is 115. if the cost of 1 book is RS 15 ,find the cost of 7 pens
Answer:
The cost of 7 pens is RS 70
Step-by-step explanation:
Let c=the cost of one book and p=the cost of one pen
5b+4p=115
b=15
5(15)+4p=115
75+4p=115
4p=115-75
4p=40
p=40/4
p=10
7p=7*10
7p=70
The cost of 7 pens is RS 70

Ryan also earns money by selling colored watch bands with the watches he sells. The linear expression 100x – 50 models Ryan's additional income. What is the expression that models the new average profit, including the bands? Note: To obtain the new average profit expression, add the linear expression to the original rational expression. Write the new profit expression as one fraction.
Answer:
Average (additional) income = 100 - 50/x
Step-by-step explanation:
Ryan's additional income = 100x - 50 , where x = quantity of colored watch bands
Ryan's additional average income = Income / Quantity of watches sold
(100x - 50) / x
= 100 - 50/x

f(x)= -3/x-3
Answer:
f(x)^-1 = 3x-3/x
Step-by-step explanation:
f(x) =-3/x-3
y= -3/x-3
x=-3/y-3
-3= (y-3)x
-3= xy-3x
-xy=-3x + 3
y= -3x +3/x
y= 3x-3/x
f(x)^-1 = 3x-3/x

-2x + y = 5
what does y equal and how did you solve it?
Answer:
y=2x+5
Step-by-step explanation:
Let's solve for y.
−2x+y=5
Step 1: Add 2x to both sides.
−2x+y+2x=5+2x
y=2x+5
Answer:
y = 2x + 5
Step-by-step explanation:
-2x + y = 5 or y -2x = 5
We want what y equals so we need to isloate it. To do this, we need to add2x to both sides. This will cancel the 2x on the left side and now we have y alone. Remember, you have to do it to both sides. Therefore:
y = 2x + 5
Note: This equation is in slope-intercept form, y= mx + b
If this was the equation of a line:
m (slope) = 2
b (y-intercept) = 5
Hope this helps!

Multiply the two binomials 6x - 5 and 2x + 3 and write your answer in
simplified terms
Answer:
x = 2
Step-by-step explanation:
6x + -5 = 2x + 3
-5 + 6x = 2x + 3
-5 + 6x = 3 + 2x
-5 + 6x + -2x = 3 + 2x + -2x
-5 + 4x = 3 + 2x + -2x
-5 + 4x = 3 + 0
-5 + 4x = 3
-5 + 5 + 4x = 3 + 5
0 + 4x = 3 + 5
4x = 3 + 5
4x = 8
x = 2
Erica can paint her room 5 hours .If she had her friend Rachel help her , they can paint the room together in 3 hours .How long would it take for Rachel to paint the room alone , if Erica wanted to go play tennis for the afternoon ?
Answer:
7 hours 30min
Step-by-step explanation:
Step one :
Given data
We are told that Erica can paint 1 room in 5hours
Her work rate is 1/5 room per hour
And also with the assistance of her friend they can paint 1 room in 3 hours
Hence their combined work rate is 1/3 room per hour
Step two
The combined work expression is
1/A+1/B=1/T
Where A=Erica's work rate
B=Rachael's work rate
T=combined work
1/5+1/B=1/3
1/B=1/3-1/5
1/B=5-3/15
1/B=2/15
B=15/2
B=7.5 hours
It will take Rachel 7 hours 30min to paint the room
Each of three colored cups covers one of three objects. 1) The red cup is somewhere to the left of the white cup. 2) The coin is somewhere to the left of the bean. 3) The gray cup is somewhere to the right of the shell. 4) The bean is somewhere to the right of the gray cup. Under which color cup is the shell?
Answer:
Shell is under Red color cup
Step-by-step explanation:
We have 3 cups and 3 objects which they cover under them.
Taking into consideration (4) and (2) as they both describe the position related to bean
(4) Gray cup →Bean (right) (2) coin ← bean (left)
that means coin can either under Gray cup or left to gray cup.
Now
(1) Red ← White (left) (3) Shell → Gray (right)
This means if we consider coin to be left of gray cup then we can't place shell to the left of gray cup as required in (3)
so coin will be under gray cup
on forming the Color of cups and the coin below them
C1 C2 C3
Red Gray White
__ __ __
Shell coin Bean
So Shell is under Red color cup
