55% of what number is 330? pls help meee

Answers

Answer:

600

Step-by-step explanation:

Assume x=target number

55%(x)=300

55%=0.55

0.55x=300

x=300/0.55

x=600

Answer

600

Step-by-step explanation:

Here is the formula/format:

Part             %

------     =    --------

Whole         100

We are trying to find the "whole" in this case, so I did:

330            55

-------   =   -------  (this says that 55% of the number we are looking for is 330)

x                100

Then, I cross multiplied and got: 55x= 33,000

From there, I divided 33,000 by 55 (inverse operations) to get x = 600.

I hope this helps! :)

Step-by-step explanation:

Answer:

15 is 20% of 75. And 15:12.

Step-by-step explanation:

Emily had 75 buttons. She gave 15 buttons to Jake. What percent of the buttons did Emily give to Jake?

She gave 15 out of her 75 buttons, so we have to figure out what percentage of buttons did she give to Jake. 20 times 5 = 100 and 5 times 15 = 75, so that is how we end up with the answer- 15 is 20% of 75.

Kelly has 15 blue bracelets and 12 green bracelets What is the ratio of Kelly's blue bracelets to green bracelets?

2. Solve the system of equations using the substitution method.
y = 10 - 4x

2x + 3y = 20
Please show how you got it

Answers

Answer:

x = 1

Step-by-step explanation:

2x + 3y = 20

2x + 3(10-4x) = 20

2x + 30 - 12x = 20

combine like terms

-10x + 30 =  20

        -30      -30

-10x = -10

divide both sides by -10

x = 1

The solution of the linear equations y = 10 - 4x and 2x + 3y = 20 will be (1, 6).

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equations are given below.

y = 10 - 4x              ...1

2x + 3y = 20          ...2

Substitute equation 1 in equation 2, then we have

2x + 3(10 - 4x) = 20

2x + 30 - 12x = 20

10x = 10

x = 1

Then the value of the variable 'y' will be given as,

y = 10 - 4(1)

y = 10 - 4

y = 6

The solution of the linear equations y = 10 - 4x and 2x + 3y = 20 will be (1, 6).

What is the solution to the equation 36 – 5x = 5 – 6(x - 4) ?

68bpoints

Answers

Step-by-step explanation:

36-5x=5-6(x-4)

36-5x=5-6x+24

-5x+6x=24+5-36

x=29-36

x=-7

Answer:

x = -7

Explanation:

36 − 5x = 5 − 6(x − 4)

[ Simplify both sides of the equation ]

36 − 5x = 5 − 6(x − 4)

36 + −5x = 5 + (−6)(x) + (−6)(−4) [ Distribute ]

36 + −5x = 5 + −6x + 24

−5x + 36 = (−6x) + (5 + 24) [ Combine Like Terms ]

−5x + 36 = −6x + 29

−5x + 36 = −6x + 29

[ Step 2: Add 6x to both sides ]

−5x + 36 + 6x = −6x + 29 + 6x

x + 36 = 29

[ Step 3: Subtract 36 from both sides ]

x + 36 − 36 = 29 − 36

x = −7

The correct option is (D).

What are Coordinates?

Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.

Given:

Diagonal vertex = (0,1 )

One vertex of the parallelogram is located at (1, 3)

and, second vertex is located at (2, 0).

Now, Going from (0,1) to (2,4) is 2 units in x- axis, 3 units in y- axis.

So, the vertex opposite (2,4) would be -2 units in x- axis, -3 units in y- axis.

= (0,1) + (-2,-3)

=(0-2, 1-3)

= (-2,-2)

and, Going from (0,1) to (3,1) is 3 units in x- axis, 0 units in  y- axis.

So the vertex opposite (3,1) would be -3 units in x- axis, 0 units in  y- axis.

= (0,1) + (-3,0)

= (-3,1)

Hence, The locations of the remaining vertices are at (−2, 2) and (-3, 1). The most specific classification of this parallelogram is a rectangle.
