Answer:
9
Step-by-step explanation:
n(A)+n(B) [n(A)=cardinal numbers of set A.so we have to count the elements and write .
=4+5
=9
Answer:
The answer is: -0.5198
Step-by-step explanation:
CUBERT(8) – CUBERT(16) is the cube root of 8 - cube root of 16:
CubeRT(8) - CubeRT(16) =
2 - 2.5198 = -0.5198
Hope this helps! Have an Awesome day!! :-)
let's set up an equation:
x-4=9
solve normally:
x=13
The height is 5 and 1/4 then the base is 2 and 1/2
You can convert these fractions into decimals and them multiply them to get your area.
Answer:
they both has 7 slides and the presentation had a duration of 28 seconds
Step-by-step explanation:
we have to setup equation that makes them equal to each other if you know what i mean. 2x+16=3x+10
then we just solve for x
2x+16=3x+10
subtract 10 from each side
2x+6=3x
step 2 subtract 2x from each side
x=6
so both of their presentations are 7 slides long
then to find the length of their presentations we just plug in 6 to one of the equations
2(6)+16
2x6=12 12+16=28 so both of their presentations were 28 seconds
