Answer:
16
Step-by-step explanation:
If x = 3 and , y = 2.
2 x 3 = 6 and 5 x 2 = 10.
10 + 6 = 16
The value of the expression 2x + 5y when x = 3 and y = 2 is 16.
We have to determine, the value of the expression 2x + 5y when x = 3 and y = 2.
According to the question,
Expression; 2x + 5y
To determine the value of the expression calculation must be done in a single unit following all the steps given below.
The value of expression 2x+5y,
When the value of x = 3 and y = 2,
Therefore,
[tex]= 2x + 5y[/tex]
Substitute the value of x = 3 and y = 2 in the given expression,
[tex]= 2(3)+ 5(2)\\\\= 6 + 10\\\\= 16[/tex]
Hence, The value of the expression 2x + 5y when x = 3 and y = 2 is 16.

Step-by-step explanation:

Answer:
(3, 4)
Step-by-step explanation:
The ordered pairs comprise a function because no x-value is repeated. If you want the list to be not-a-function, then one of the x-values must be repeated.
The x-values given in the original function list are -2, 3, 7, 9. The only one of these that is an x-value in an answer choice is 3, in the pair (3, 4).
Adding (3, 4) will make the relation not a function.
55% of what number is 330? pls help meee
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! :)

The diagonals of a parallelogram meet at the point (0, 1). One vertex of the parallelogram is located at (1, 3), and a second vertex is located at (2, 0). Find the locations of the remaining vertices, and determine the most specific classification of this parallelogram.
The locations of the remaining vertices are at (−2, 1) and (−1, −2). The most specific classification of this parallelogram is a square.
The locations of the remaining vertices are at (−2, 1) and (−1, −2). The most specific classification of this parallelogram is a rhombus.
The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a square.
The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a rectangle.
Answer:
The answer is C
Step-by-step explanation:
The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a rectangle.
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.

Ahmad just bought a used sailboat with two sails that need replacing. How much sail fabric will Ahmad need if he replaces sail A?
PLZ HELP
Answer:
sail a = 81ft²
sail b base = 12ft
Step-by-step explanation:
question 5:
the measurements for sail A are 18ft(height) and 9ft (base)
the formula to find the the area of a triangle is (b · h) 1/2
(9 · 18) 1/2 = (162) 1/2 = 81
so ahmad will need 81ft² of fabric for sail a
question 6:
we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.
(b · 18) 1/2 = 108
[tex]\frac{(b . 18) 1/2}{1/2}[/tex] = 108/ 1/2
(b · 18) = 216
18b = 216
18b/18 = 216/18
b= 12
check your work:
(12 · 18) 1/2 = 108
(216) 1/2 = 108
108 = 108 true!
the base measurement for sail b is 12ft
hope this helps and have a great day!!

Kelly has 15 blue bracelets and 12 green bracelets What is the ratio of Kelly's blue bracelets to green bracelets?
Answer:
1. $1.15 a jar, 2. 11% 3. 15 to 12
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?
When you are doing ratios, all you have to do is put the two numbers in ratio form, such as 15:12.

What is the solution to the equation 36 – 5x = 5 – 6(x - 4) ?
68bpoints
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
