Given :
A patient with high blood pressure who weighs 226 pounds is put on a diet to lose 26 pounds in 3 months. The patient loses 8 3/4 pounds the first month and 11 5/8 pounds the second month.
To Find :
How much weight must be lost the third month for the goal to be achieved.
Solution :
Let, weight lose in third month is x.
So, 8 3/4 + 11 5/8 + x = 26
[tex]\dfrac{32+3}{4}+\dfrac{88+5}{8}+x=26\\\\x = 26 - ( \dfrac{35}{4}+\dfrac{93}{8})\\\\x=5.625\ pounds[/tex]
Therefore, weight lose in third month is 5.625 pounds.
Hence, this is the required solution.

Steve stayed after school for extra activities 55% of the 180 school days this year. How many days did Steve stay after school?
Answer:
11/20 or 99/180 days
Step-by-step explanation:
55/100 converted to ?/180
180/100=1.8
so you would do the same on the numerator which is 55*1.8=99
99/180= 33/60=11/20
Answer:
125

When an article is sold at a discount of 10 %, a profit of Rs 8 is earned. If the same
article is sold without allowing a discount, there will be a profit of Rs 20. Find the cost price of the article.
Answer:
Market Price = MP
Cost Price = CP
P1 = (MP - 10%) - CP = Rs8
- CP = Rs8 - 0.90% MP
CP = 0.90 MP - Rs8
P2 = MP - CP = Rs20
- CP = Rs20 -MP
CP = MP - Rs20
0.90 MP - Rs8 = MP - Rs20
- 0.10% MP = - Rs12
0.10% MP = Rs 12
MP = Rs120p
CP = MP - Rs20 = Rs120 - Rs20 = Rs100.
The cost price of the item is Rs100.

Solve each equation.
7(1 +4n) - 5=-38 + 8n
Answer:
B) n=-2
Step-by-step explanation:
First, distribute.
7(1+4n)-5=-38+8n
7+28n-5=-38+8n
Combine like terms.
2+28n=-38+8n
To make solving the equation easier, subtract 8n first, so there isn't a negative variable.
2+28n=-38+8n
-8n -8n
2+20n=-38
Subtract 2 on both sides.
2+20n=-38
-2 -2
20n=-40
Divide by 20 on both sides.
20n=-40
/20 /20
n=-2

i need help with this geometry
Answer:
c
Step-by-step explanation:
use point slope form y-y1 = m(x-x1)
m = -1/2 because that would be perpendicular
then you plug in the numbers y-6= -1/2(x-4)
then solve for y so i will be in y=mx+b

given the equation y=23x,whats the value of x if y=100
Answer: 4.3478 or 100/23
Step-by-step explanation:
Set the y values equal to each other since they are the same unknown (x). You end up with 100=23x, solve for x. Move the 23 over to the other side by using division. x=100/23. If you need it in decimal form, 100÷23=4.347826087
Answer:
4.3=x
Step-by-step explanation: y=23x
substitute the variable y to 100. Now the equation looks like this 100=23x. Your next step is to get get x by itself, so you would divide 23 on both sides. That would cancel out the 23 x. The only thing you have to do now is 100 divided by 23 and that would be 4.3 and a whole bunch of number so you just round it to the nearest tenth. You answer would be 4.3.

-6a - 4(a - 3) = -6a + 15
Step-by-step explanation:
-6a - 4(a - 3) = -6a + 15
=> -6a - 4a + 12 + 6a - 15 = 0
=> -4a - 3 = 0
=> -4a = 3
=> a = -3/4

#30 Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1,030 was
collected. Let x represent the number of tickets sold at the door.
In terms of x. how many tickets were sold in advance?
Answer:
170 tickets were sold in advance
Step-by-step explanation:
Let x represent the = number of tickets sold at the door.
Let y represent the = number of tickets sold in advance
Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1,030 was
collected.
Hence, we have two equations
x + y = 400 tickets
$3 × x + $2 × y = $1,030
x + y = 400.... Equation 1
x = 400 - y
3x + 2y = 1030........ Equation 2
Substitute 400 - y for x in Equation 2
3(400 - y) + 2y = 1030
1200 - 3y + 2y = 1030
Collect like terms
-y = 1030 -1200
-y = -170
y = 170
Since y represent the number of tickets sold in advance, therefore, 170 tickets were sold in advance.

What value of x will make the equation true? 1/4x - 5 = 2
Answer:
28
Step-by-step explanation:
Step 1:
1/4x - 5 = 2 Equation
Step 2:
1/4x = 7 Add 7 on both sides
Step 3:
x = 7 ÷ 1/4 Divide
Answer:
x = 28
Hope This Helps :)
Answer:
28
Step-by-step explanation:
Add 5 to each side, so it now looks like this: 1/4x = 7Divide each side by 1/4 to cancel out the 1/4 next to x. It should now look like this: x = 28I hope this helps!

What is the solution to the equation –5w + 3 = 4w – 6?
Answer:
-2=2
Step-by-step explanation:
Answer:
w = 3
Step-by-step explanation:
-5w + 3 = 4w - 6
were going to get the variable and the numbers on different sides
-5w + 3 - 3 = -5w
4w - 6 - 4w = -6
-5w + 4w = -1w or -w
-6 + 3 = -3
-w = -3
and since there're both negatives you can just take that away and you get
w = 3

In Akutan, Alaska, men are 77% of the population. It is also known 11.3% of
Akutan males smoke cigars while 2.1% of Akutan females smoke cigars. One
member of the population is selected at random for a survey involving cell
phone carriers
Express the cigar smoking data as conditional probabilities.
Find the
probability that the selected subject does not smoke cigars given that the
subject is male
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Proportion of males, P(M) = 77% = 0.77
Proportion of females = ( 1 - proportion of males) = (1 - 0.77) = 0.23
Percentage of males who smoke cigar = 11.3% = 0.113
Percentage of female who smoke cigar = 2.1% = 0.021
Expressing cigar smoking Data as conditional probability :
P(male and smoking) = P(M n C) = 0.113
P(Female and smoking) = P(F n C) = 0.021
Probability of smoking cigar Given the person is a male :
P(C | M) = P(M n C) / P(M)
Probability of smoking cigar Given person is a female :
P(C | F) = P(F n C) / P(F)
Find the probability that the selected subject does not smoke cigars given that the subject is male?
No smoking Given Male = 1 - P(C | M)
P(C | M) = P(M n C) / P(M)
P(C | M) = 0.113 / 0.77
P(C | M) = 0.1467
1 - P(C | M)
1 - 0.1467
= 0.8533

-2/3y-3/4=5
What is the answer i need to show my work please
Answer:
y= -69/8 (negative 69 over 8)
Step-by-step explanation:
First, you have to simplify both sides of the equation:
[tex]-2/3y+ -3/4 =5[/tex]
Second, add 3/4 to both sides:
-2/3y +-3/4 + 3/4=5 +3/4
-2/3y= 23/4
Next, multiply both sides by 3/(-2) (3 over -2)
(3/-2)*(-2/3y)= (3/-2) * (23/4)
y= -69/8
