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.

Answer:
I don't know if you have given the full question.
Step-by-step explanation:
but from what you have typed I understood that ( -x ) = - ( x)
positive × positive = positive
negative × negative = positive
positive × negative = negative
so from this we derive -x = -x ( when we open the bracket negative 1 is multiplied to x)

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
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
Step-by-step explanation:
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

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.
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.
1.) Yvonne purchased $46 worth of items for a theme party. A small bag of party hats cost $2.75, a pack of napkins cost $3.50, and a set of cups and plates cost $2.00. If Yvonne bought 4 bags of hats, and 2 packs of napkins, how many cup and plate sets did she buy?
Answer:
14
Step-by-step explanation:
$46 in total
Hats: $2.75 * 4 bags = $11
Napkins: $3.50 * 2 packs = $7
11 + 7 = 18
$46 - $18 = $28
$2.00 / 28 = 14
If cups and plates were $2.00, that means it would take 14 sets to fill the remaining $28.

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.

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.
х+ 5y = 16

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
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
