[tex]s^2=1^2+2^2\\s^2=1+4\\s^2=5\\s=\sqrt5[/tex]
s²=5 , so we look for the nearest squares, one less than 5 and the other greater.
First it would be perfect squares, which means 4=2² and 9=3²
4 < 5 < 9 so 2 <√5 < 3
now we'll do the same with the numbers with tenths, but to speed up we don't check them all. We do estimation for the square root knowing that it must be between 2 and 3
5 is close to 4 then 9, so I estimate 2.3 for its square root
(2.3)² = 5.29 - it is close but more then 5 so I look for less number then 2.3
(2.2)² = 4.84 - it is also close and less then 5 so:
4.84 < 5 < 5.29 therefore 2.2 < √5 < 2.3 and:
5 - 4.84 = 0.16 ; 5.29 - 5 = 0.29
0.16 < 0.29 means the √5 is closer to 2.2 then 2.3
So the √5 rounded to the nearest tenth is 2.2
Of course is much easier if you can use the calculator. Then you have:
√5 = 2.2360679... ≈ 2.2 {because 3<5}

If the equation of a line is y= - 2/3 x - 2 at what.point on the graph would I find the y- intercept?
Answers
Answer:
(0, -2)
Step-by-step explanation:
The slope equation is written as y = mx + b where m is the slope and b is the y-intercept. In this equation the slope, which is m, is -2/3 and the y-intercept is -2, which is the value of b. So the y-intercept on the graph would be found at point (0, -2)
Let y = mx +b, where m is the slope of the equation and b is the y-intercept.
So from the equation [tex]y=-\frac{2}{3}x-2[/tex] You'd find the y-intercept at (0,2). Alternative way, you can find the y-intercept by substituting x = 0 so -2x/3 will be 0 because x = 0 and -2x(0)/3 = 0-2 = -2.
So from the y = mx + b, you would find the y-intercept at (0,b)

What is the solution to
5 + 3(x - 1) = 3x + 14 - (x +15)
Answers
Answer:
x = -3
Step-by-step explanation:
5 + 3(x - 1) = 3x + 14 - (x +15)
5 + ( 3x - 3 ) = 3x + 14 - x -15
3x + 2 = 2x - 1
x + 3 = 0
x = -3
Answer:
x = -3
Step-by-step explanation:
To find the solution to the equation, we would have to find a value of x that would satisfy the equation.
5 + 3(x - 1) = 3x + 14 - (x + 15)
Distribute the 3 on the left side and the - on the right side.
5 + 3x - 3 = 3x + 14 - x - 15
Combine like terms.
2 + 3x = 2x - 1
Subtract 2 from both sides.
3x = 2x - 3
Subtract 2x from both sides.
x = -3
So the solution to the equation would be x = -3.

snack costs $1.25, and
each can of soda costs s
dollars. Xavier's total for
the snacks and soda was
$8. How much did each
can of soda cost?
Answers
Answer: Each can of soda costed $1.50
Step-by-step explanation:
The total cost was $8
Xavier's bought 4 snacks; each $1.25
4 x 1.25 = $5
How much for 2 cans of soda?
Well we know how much the snacks were ($5) and the total cost was $8, so the 2 cans costed $3 because 5 + 3 = 8. But how much did each can cost? Each can costed $1.50 because if the 2 cans costed $3, and we wanted to know how much 2 costed, we would have to divide 3 by 2 which is 1.50. So each can costed $1.50

Solve for D
Answers
Answer:
D = [tex]\frac{n-5m^2}{5}[/tex]
Step-by-step explanation:
Given
n = 5(m² + D) ← distribute
n = 5m² + 5D ( subtract 5m² from both sides )
n - 5m² = 5D ( divide both sides by 5 )
[tex]\frac{n-5m^2}{5}[/tex] = D
The solution of the expression for the value of D will be D = (n - 5m²) / 5
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is n = 5(m² + D). The value of D will be calculated as below:-
n = 5(m² + D) ← distribute
n = 5m² + 5D ( subtract 5m² from both sides )
n - 5m² = 5D ( divide both sides by 5 )
(n - 5m²) / 5 = D
Therefore, the solution of the expression for the value of D will be D = (n - 5m²) / 5

Given :
Eddie went to a Nascar race and brought $55 with him to spend.
Admission cost him $35 and sodas were $6.25 each.
To Find :
A) Write an inequality that represents how many soda's Eddie can buy.
B) What is the greatest number of sodas Eddie can buy.
Solution :
A)
Let, after buying x soda cans money spend is y.
So, [tex]y=6.25x +35[/tex]
It is also given that maximum money he have is $55 .
So, 6.25x + 35 ≤ 55
B)
Now,
6.25x ≤ 20
x ≤ 3.2
i.e x ≤ 3
Therefore, greatest number of sodas Eddie can buy is 3.
