Find two numbers if their ratio is 9:11 and their difference is 6 THERE ARE TWO ANSWERS!!
Step-by-step explanation:
x, y are the 2 numbers.
x/y = 9/11
x - y = 6
x = y + 6
now we use that in the first equation
(y + 6)/y = 9/11
y + 6 = 9y/11
11y + 66 = 9y
2y = -66
y = -33
x = y + 6 = -27
but the second equation could also be
y - x = 6
then
x = y - 6
and that in the first equation leads to
(y - 6)/y = 9/11
y - 6 = 9y/11
11y - 66 = 9y
2y = 66
y = 33
x = y - 6 = 27
what are the solutions of x^2-4x+5=0
A. x=2+i/3 or x=2-i/3
B. x=1+i/2 or x=1-i/2
C. x=3+i or x=3-i
D. x=2+i or 2-i
Answer:
Should be D.
Step-by-step explanation:
Because you can't factor the equation you use the quadratic formula. By using it you should get 4 plus or minus the square root of -4 all over 2. Simplified would be 2 plus or minus i
х+ 5y = 16
х+ Зу = 10
x=?
y=?
Answer:
x=1 y=3
Step-by-step explanation:
x+5y=16
x+3y=10
2y=6
y=3
x+15=16
x=1
verify
1+9=10
Answer:
x = 1 , y = 3
Step-by-step explanation:
x + 5y = 16 → (1)
x + 3y = 10 → (2)
Subtract (1) from (2) term by term to eliminate x
0 + 2y = 6
2y = 6 ( divide both sides by 2 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 5(3) = 16
x + 15 = 16 ( subtract 15 from both sides )
x = 1

To get to the camp in time, tourists had to go with a speed 4km/h. They went with that speed half of the road, but then they drove with a bus and arrived to the camp 2h 20min before the planned time. How many kilometers did tourists drive with the bus, if the speed of the bus was 60km/h?
Answer:
it is solved at jemrare dot com
Step-by-step explanation:
This problem can be solved using distance formula;
s=vt
Here we suppose;
Speed of Tourists=v1=4 km/h
speed of bus=v2=60km/h
Total time to be taken by the tourists to reach the camp without bus=t
Time taken by tourists when bus used=t-2h20min=t-140min
let the total distance is ‘x’ but half is travelled without bus and other half by bus!
for first half distance=s1 =x/2
for second half distance=s2=x/2
Using s=vt formula for first half;

how much will I pay for 4m of cloth if 1 m cost $17.25?
Answer:
you will pay $69 for 4m of cloth if 1m costs $17.25
Step-by-step explanation:
17.25 x 4 = 69
If 4x - 9 = 35,
find the value of 6x + 4
Step-by-step explanation:
4x=44
x=11
6x+4= 6*11+4= 70
Answer:
6x+4=70
Step-by-step explanation:
To solve this, first, we need to know what x is. To do this, we need to solve the equation:
4x-9=35
The first step to solving this is to add nine to both sides, since we need to do the inverse of subtraction to get our answer.
4x-9+9=35+9
4x=44
Now, do the inverse of multiplying by four, which is dividing by four, to both sides.
4/4x=44/4
x=11
Now that we know what x is, we can find the value of 6x+4. Simply plug in 11 for x.
6(11)+4
66+4
70
Our answer is 70.
9. A tailor has 23 metres of cloth. She wants to make 7 baju kurung of the same size. She then has 2 metres of cloth left. How many metres of cloth did she use to make each baju kurung?
Answer:
The tailor used 3m per baju kurung.
Step-by-step explanation:
The tailor began with 23m of cloth and at the end had 2m of cloth left. You calculate how many meters of cloth she used all together by subtracting 2 from 23:
23m - 2m = 21m
Then you find out how many meters she used per baju kurung by dividing 21 by 7:
21m / 7m = 3m

Wen says the function is continuous, because the number of people is unlimited. Is Wen right or wrong?
Answer Wen is incorrect. The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.

Maggie spent $4.05 dollars on cheese and fruit at the farmer's market. She bought 1/8 pound of apples,1/4 pounds of pears,and 1.25 pounds of bananas. If fruit cost $0.80 per pound ,how much did Maggie spend on cheese?
Total weight of fruit: 1/8 + 1/4 + 1.25 = 1.625 pounds
Cost of fruit: 1.625 x 0.80 = $1.30
Cost of cheese = total spent - cost of fruit:
Cost of cheese = 4.05 - 1.30 = $2.75
Answer: $2.75
Answer:
1+2=3
3×0.8=2.4
4.05-2.4=1.65

pls helpppppppppppppppp Which value of y makes the equation 12y−3=5 true?
y is equal to 2
y is equal to 1
y is equal to 2 thirds
y=13
Answer:
y = 2/3
Step-by-step explanation:
so 12y-3=5, add the 3 to the 5 to get 12y=8. Then divide the 12y by 12 and the 8 by 12. In so you geet y=2/3
Answer:
y is equal to 2 thirds (y = 2/3)
Step-by-step explanation:
12y − 3 = 5
Substitute the given options to see which one will provide a true statement:
If y = 2:
12y − 3 = 5
12(2) − 3 = 5
24 − 3 = 5
21 = 5 (False statement, so it's not the right answer).
If y = 1:
12(1) − 3 = 5
12− 3 = 5
9 = 5 (False statement).
If y = 2/3:
12(2/3) − 3 = 5
8 - 3 = 5
5 = 5 (True statement).
If y = 13:
12(13) − 3 = 5
156 - 3 = 5
153 = 5 (False statement).
Therefore, the correct answer is: y = 2/3.
12/x=45
What would x equal
Answer:
=4/15
=0.26
Step-by-step explanation:
Answer:
x = 4/15
Step-by-step explanation:
Step 1: Multiply both sides by x.
[tex]\frac{12}{x} * x = 45 * x[/tex] [tex]12 = 45x[/tex] [tex]45x = 12[/tex]Step 2: Divide both sides by 45.
[tex]\frac{45x}{45} = \frac{12}{45}[/tex] [tex]x = \frac{4}{15}[/tex]Therefore, x = 4/15.

Step-by-step explanation:
Given the linear function, w(x) = 3/5x + 2, where the slope, m = 3/5, and the y-intercept is (0, 2).
Start by plotting the y-intercept on the graph. Then, use your slope, m = 3/5 (rise 3 units, run 5 units) to plot other points on the graph.
Attached is an edited screenshot of your given problem, which shows the plotted points on the graph using the techniques explained in this post.
