What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
Answer:
9.25
Step-by-step explanation:
5(0.3) = 1.5
20-1.5=18.5
18.5÷2=9.25
Answer:
y = 9.25Step-by-step explanation:
5x + 2y = 20
when x = 0.3 we have
5(0.3) + 2y = 20
1.5 + 2y = 20
Using the subtraction property subtract 1.5 from both sides of the equation
That's
1.5 - 1.5 + 2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
[tex] \frac{2y}{2} = \frac{18.5}{2} [/tex]
We have the final answer as
y = 9.25Hope this helps you
What is the domain and range in this graph?
Step-by-step explanation:
The graph starts when the value of x is -1 and ends when it's value is 5 , So domain is [-1,5]
The highest value of the graph is 4 which is at x = -1 and the lowest value of the graph is 0 , which is at x = 5, So range is [0,4]
The domain is equal to all the input values (x-values)
The range is equal to all the output values (y-values)
In this problem,
The domain: [-1, 5]
The range: [0, 4]

here are the first four terms in a sequence: 6, 10, 14, 18
the number 102 is NOT a term in this sequence. explain why.
thanks :)
Answer:
common difference = 4
if 102 is a term in sequence n should have non decimal value
a +(n-1)d = 102
0r 6 + (n-1)4= 102
0r, 4(n-1) = 96
or n-1 =24
n =25

7 students have 3 books each. Which helps you find the total number of books?
Answer:
21 Books in total
Step-by-step explanation:
If you just want the total number of books, here:
If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books
7 * 3 = 21 so There are 21 books in total
Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.
Answer:
21 books in total
Step-by-step explanation:
If there is 7 students who have 3 books each, and want to find the total. The easiest way is multiply 7 with 3 to give you an answer of 21
Or draw a picture if it helps
Draw 7 stick figure and under it draw 3 books for them and count the books, still gives you 21

Number 4if x represent the numbers of pencils per box solve the equation 8x4=196so,she put 4 in each boxFind the distance between the two points rounding to the nearest tenth (if necessary)
(-3,3) and (-1,5)
Answer:
The answer is
2.8 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-3,3) and (-1,5)
The distance is
[tex]d = \sqrt{( { - 3 + 1})^{2} + ({3 - 5})^{2} } \\ = \sqrt{ ({ - 2})^{2} + ( { - 2})^{2} } \\ = \sqrt{4 + 4} \\ = \sqrt{8} \: \: \: \: \: \: \: \: \\ = 2 \sqrt{2} \: \: \: \: \: \: \\ = 2.82842[/tex]
We have the final answer as
2.8 units to the nearest tenthHope this helps you

Step-by-step explanation:
what is the smallest two digit positive integer such that the product of its two digits is one-half the integer
Let x be the tens and y be the ones digits.
The product of the number is then: 10x + y
The product is 1/2, so you need to multiply the product by 2 and the number:
10x + y = 2(x+y)
10x + y = 2x + 2y
Subtract 1 y from both sides
10x = 2x + y
Subtract 2x from
Both sides
8x = y
X has to be 1 , which would make y 8
The product number becomes 18
Since the product is 1/2, multiply by 2:
18 x 2 = 36
3 x 6 = 18
The answer is 36

Is it true that square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol?
Answer:
Yes
Step-by-step explanation:
I had this same question on a quiz and it is correct!
The square root of a number is equal to another number that when squared is equal to the original number.
Now we want to see if Is it true that square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol, and we will see that yes, this is true.
To see that this is true:
For example, if the A and B are two numbers larger than 0, such that:
A > B
Then:
√A > √B
For example let's use A = 9 and B = 4.
9 > 4
And obviously the roots are:
√9 > √4
3 > 2
So yes, we can compare and order square roots by comparing the numbers inside of it.
