Answer:
There are 800 girls and 1000 boys.
Step-by-step explanation:
The total no of students enrolled = 1800
Ratio of boys to the girls is 4:5.
Let there are 4x boys and 5x girls.
ATQ,
4x+5x=1800
9x=1800
x = 200
No of boys = 4x = 4(200) = 800
No of girls = 5x = 5(200) = 1000
So, there are 800 girls and 1000 boys.

1/2y+6x-36=0 I need help finding the equation for y
Answer: y=−12x+72
Add -6x to both sides.
You should get: 1/2y - 36 = -6x
Add 36 to both sides.
1/2y = 36 - 6x
Divide both sides by 1/2.
Which gives you
y = -12x +72
I don't know if this is the answer you're looking for but hopes this helps

The value of x in terms of b is x = -3/b
The value of x when b is 3 is x = -1
===========================================
Work Shown:
Let's isolate x
-2(bx - 5) = 16
bx - 5 = 16/(-2) ... dividing both sides by -2
bx - 5 = -8
bx = -8+5 ... adding 5 to both sides
bx = -3
x = -3/b ... dividing both sides by b
That wraps up the first part.
-----------
To answer the second part, we plug in b = 3 to get
x = -3/b
x = -3/3
x = -1

Can someone please help me ???
Answer:
C
Step-by-step explanation:
how do you know if an equation has infinite solutions?
if the equation ends with a true statement, like 3=3, then you know it has sinfinite solutions. in this situation x=x
C:
3(2x+1)=6x+3
(multiply 3 by (2x+1))
6x+3=6x+3
(subtract 6x-3 from both sides)
0=0

Answer: Option B - 3 1/2
Step-by-step explanation:
Using the graph they give you on your problem, you can see that they split the fourths into eighths for you. To find how much sauce Alfredo has, you can count the little squares at the bottom up to 7. Then, you check where that is relative to the top squares. When you finish counting, you will see you have passed 3 of the 1/4 size boxes and you are halfway through the last 1/4 size box. Therefore, Alfredo can make 3 and 1/2 servings.
What is the domain of the given function ?
Answer:
I believe it is a. {x | x = -6, -1, 0, 3}, but I could be wrong.
Step-by-step explanation:
The graph shows the locations of point C and point D. Point E is graphed at (n, 2).
The distance from point D to point E is equal to the distance from point D to point C.
What is the distance from point D to point E? What is the value of n? Enter your answers in the boxes.

Are 67.13 and 63.10 equivalent decimals yes or No?
Answer: No
Step-by-step explanation:
67.13>63.10

daniel earns extra money as a lifeguard he earns 37 dollars for 4 hours and 64.75 for 7 hours. the relationship between his earnings and the time worked is proportional true or false?
Answer: Yes, it is proportional.
Step-by-step explanation:
Find the amount Daniel earns each hour.
Divide the amount of money by the number of hours to find each earnings per hour.
Life guard: $37 for 4 hours.
37/4 = 9.25
64.75/ 7 = 9.25
Since Daniel receives the same amount of money per hour which is $9.25 per hour, then the relationship is proportional.

Salam walks along a path surrounding a circular pond. The paths radius is 150 meters. Salam walks 75 meters per minute. About how long does it take Salam to walk around the path once.
Answer:
The time it takes Salam to walk around the path once is 12 minutes 34 seconds
Step-by-step explanation:
Given;
radius of the circular pond, r = 150 m
speed of Salam, v = 75 m/min
A single distance round the circular path is given by;
d = 2πr
d = 2π(150)
d = 942.6 m
Time it takes Salam to walk around the path once, is given by;
time = distance / speed
time = 942.6 / 75
time = 12.568 minutes
time = 12 minutes 34 seconds
Therefore, the time it takes Salam to walk around the path once is 12 minutes 34 seconds
Sheila has 11 1 2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 1 4 pounds. How many containers does she need?
Answer:
9 containers
Step-by-step explanation:
Given
Total pounds of potato salad = 11 1/2 pounds
If one container holds 1 1/4 pounds:
The number of container that 11 1/2 pounds can hold is expressed as:
Number of container = Total pounds/volume of one container
Number of container = 11 1/2 ÷ 1 1/4
Convert to improper fraction
Number of container = 23/2 ÷ 5/4
Number of container = 23/2 × 4/5
Number of container = 92/10
Number of container = 9.2
Therefore she will need 9 containers

The johnsons annversary party will cost 48 dollars if 12 people come to the party. It will cost 88 dollars if 22 people come to the party. What is the cost per gusset.
Answer:
Cost per gusset = 4
Step-by-step explanation:
Given:
Cost for 12 people party = $48
Cost for 22 people party = $88

Cost per gusset
Computation:
Cost per gusset = 48 / 12
Cost per gusset = 4
Cost per gusset = 88 / 22
Cost per gusset = 4
write an equation of the line with a slope of 4/5 and a y intercept of 0
Answer:
y = 4/5x
Step-by-step explanation:
slope intercept form is written as y = mx + b. the m represents slope, and the b represents y intercept. replace the variables with the numbers (since y intercept is 0, leave it blank) and you're left with y = 4/5x. hope this helps :)
