Answer:
-77k²m³
Step-by-step explanation:
The variable arrangement is the same for each term, so we simply combine their coefficients:
k²m³ +22k²m³ -100k²m³ = (1 +22 -100)k²m³ = -77k²m³
Answer:
Step-by-step explanation:
If Jason travel 24 miles in 1/2 hour, he will travel 2*24=2*1/2h
48 miles/hour
or
24 miles...............................30 min
? miles in .............................60 min
(60*24)/30=48
Billy would have of scored a total of 40 points because then you split 90 in half you get 40 50 and then 50 is 10 more than 40 and logan scored 10 more so here is your answer
It depends on what variable you are tying to solve for first. Say you are trying to solve for x first and then y on the first problem you wrote.
In substitution you solve one of the equations for example with
6x+2y=-10
2x+2y=-10
you solve 2x+2y=-10 for x
2x+2y=-10
-2y = -2y (what you do to one side of the = you do to the other)
2x=-10-2y (to get the variable by its self you divide the # and the variable)
/2=/2 (-10/2=-5 and -2y/2= -y or -1y, they are the same either way)
x=-5-y
now you put that in your original equation that you didn't solve for:
6(-5-y)+2y=-10 solve for that
-30-6y+2y=-10 combine like terms
-30-4y=-10 get the y alone and to do this you first get the -30 away from it
+30=+30
-4y=20 divide the -4 from each side
/-4=/-4 (20/-4=-5)
y=-5
now the equation you previously solved for x can be solved for y.
x=-5-y
x=-5-(-5) a minus parenthesis negative -(- gives you a positive
-5+5=0
x=0
and now we have solved the problem. x=0 and y=-5
Hi there! The answer is 9 square units
To find the area of a triangle we use the following formula:
Area = 0.5 * base * height.
The base of this triangle:
AC = 6
The height of this triangle:
BD = 3
Filling in this formula gives us:
Area = 0.5 * 3 * 6 = 9
Therefore, the answer is 9 square units
