Answer:
it will take 2 minute 30 seconds
Step-by-step explanation:
Cheeta DATA:
rate = 18 m/s ; time = t seconds ; distance = rt = 18t meters
Gazelle DATA:
rate = 16 m/s ; time = t seconds ; distance = rt = 16t meters
Equation:
gazelle +300 meters = cheetah
16t + 300 = 18t
2t = 300
t = 150 seconds (time for the cheetah to catch the gazelle)
12x2-7=6-2x2+2
14x^2-15=0
a=14 , b =0 , c=-15
0^2-4x14x(-15) =
840
According to the given descriptions to create a figure of lines, the answer is transitive property. Transitive property relates two angles that are separately proven by different theorems and making a statement that connects or relates the congruence of two angles or even two sides.
Let a and b = the numbers we must find.
a + 2b = 5.....Equation A
2a + b = 13.......Equation B
We have a system of equations in two variables.
I will solve A for little a.
a + 2b = 5
a = 5 - 2b
Now I will plug 5 - 2b for a in B.
2(5 - 2b) + b = 13
10 - 4b + b = 13
-3b = 3
b = -1
To find a, replace b with -1 in EITHER A or B.
I will use Equation A.
a + 2b = 5
a + 2(-1) = 5
a - 2 = 5
a = 7
The two numbers are -1 and 7.
Understand?
I don't see what we need to multiply but here is an example: the numbers of the equation that I'm doing is 12 times 13 and this is how I do it .
(1)(2) Step 1: multiply 3 times 2 then when you get the
x 1 (3) answer you would need to multiply then 2 times 3.
-------
(36) ( when multiplying 1 times 3 and then multiply 2 times 3)
Step 3: know that in the third step you would need to multiply 1 times 2 then 1 times 1.
(1)(2)
x(1) 3
-------------
36
+ 120 (when multiplying 1 times 2 then 1 times 1 but I added a zero )
-----------
156 ( I add them all up and that's the answer )
