Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
45 + 25x = 65 + 15x

x = 2
A person's heart rate is typically between 60 and 100 heart beats per minute noah looks at his watch and count's 8 heart beats in 10 seconds is his heart rate typical?
Answer:
No
Step-by-step explanation:
So Noah’s Heart beats 8 beats in 10 seconds. There are 60 seconds in a minute.So you multiply 8 by 6, ( because 10 x 6 is 60, or 1 minute) To get 48, Which is below the average Heart rate.

What's the slope of the line?
Answer:
3
Step-by-step explanation:
lets just take two random points that are on the line ( it doesn't have to be a specific point)
(-2,0) and (-1 , 3) cuz why not
we need to find the difference of both the y coordinates divided by the difference of both the x coordinates
0-3 / -2 - (-1)
-3 / -1
3/1 = 3

choose two random points of the line and....

Explain how to find the value of y in the equation 6(y+4)=12
Answer:
y=-2 (Please can i have brainliest????)
Step-by-step explanation:
There are different ways to do this but my way, you would distribute 6 to both y and 4, ending up with 6y+24=12. You then subtract 24 from both sides giving you, 6y=-12. Then divide both sides by 6, giving you y=-2
Answer: y=-2
Step-by-step explanation:
First, you would distribute the 6 to both the y and the 4 which would give you 6y+24=12
Then you would subtract 24 from 12 to get -12 ( it would look like 6y= -12 after)
Finally, you would take -12/6 to get -2 so y = -2

Answer:
7.2
Step-by-step explanation:
Use the distance formula:
d = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
Points of the diagonal: (-2, -2) and (2, 4)
d = [tex]\sqrt{(2-(-2))^2+(4-(-2))^2}[/tex]
d = [tex]\sqrt{(2+2)^2+(4+2)^2}[/tex]
d = [tex]\sqrt{(4)^2+(6)^2}[/tex]
d = [tex]\sqrt{16 + 36}[/tex]
d = [tex]\sqrt{52}[/tex]
d ≈ 7.2
The product of two consecutive numbers is 72. Use a quadratic equation to find the two sets of numbers.
Given:
The product of two consecutive numbers is 72.
To find:
The two numbers by using the quadratic equation.
Solution:
Let the two consecutive numbers are x and (x+1).
The product of two consecutive numbers is 72.
[tex]x(x+1)=72[/tex]
[tex]x^2+x-72=0[/tex]
Splitting the middle term, we get
[tex]x^2+9x-8x-72=0[/tex]
[tex]x(x+9)-8(x+9)=0[/tex]
[tex](x+9)(x-8)=0[/tex]
Using zero product property, we get
[tex]x+9=0[/tex] and [tex]x-8=0[/tex]
[tex]x=-9[/tex] and [tex]x=8[/tex]
If [tex]x=-9[/tex], then
[tex]x+1=-9+1[/tex]
[tex]x+1=-8[/tex]
If [tex]x=8[/tex], then
[tex]x+1=8+1[/tex]
[tex]x+1=9[/tex]
Therefore, the two consecutive numbers are either 8,9 or -9,-8.

Answer:
They say.. use Pythagorean theorem formula.... what is it? :) you have to remember it. I'll put it below in case you don't remember
Step-by-step explanation:
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] +[tex]B^{2}[/tex]
and I know, you're thinking..... what's the deal with all the letters... how do I add those up? :D ..... you are right... you can't add letters... the letters are just the variables... or places holders for numbers... you can put many different numbers into each of them but... the relationship.... which is made by the equal sign.. must hold true for any numbers you put in for the variables.... sooo.. like this.. for your particular answer
[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]
( notice I've put in a " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number... soooo..... )
361 = 100 + [tex]y^{2}[/tex] ( subtract 100 from each side of the " = " )
261 = [tex]y^{2}[/tex] ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y
my calculator tells me that [tex]\sqrt{261}[/tex] = 16.15549442
they say round to the nearest 10th... soooo..
16.2 is the answer :)

Answer:
422.5
Step-by-step explanation:
Given,
Diameter = 23.2
Radius = 23.2 ÷ 2 = 11.6
So, Area is
[tex] = \pi {r}^{2} [/tex]
[tex] = 3.14 \times 11.6 \times 11.6[/tex]
= 422.5184
As rounding to nearest tenth we check the hundreth digit i. e.
422.5184
Since, 1 is smaller than 5 so,
422. 5 (Ans) (Rounded to nearest tenth)

ellen has a coupon for 1.55 off a loaf of bread. the regular price of the bread is 4.63. the loaf is cut into 14 slices. what is the price per slice if ellen uses her coupon?
Answer:
$0.22
Step-by-step explanation:
Ellen has a coupon of 1.55 off a loaf of bread
The regular price of the bread is 4.63, the loaf is cut into 14 slices
Therefore if she uses her coupon the price per slice can be calculated as follows
= 4.63-1.55
= 3.08
3.08/14
= 0.22
Hence the price is $0.22
