Answer:120
Step-by-step explanation:
Answer:
<u>D</u>
Step-by-step explanation:
The logical step is to <u>factorize the left side of the equation</u>, which becomes:
Then, you can take the square root on both sides.
Not asked, but good to understand the procedure regardless.
The last graph represents a system with no solutions. The solution to a system of equations is the point at which both lines intersect. Because the equations in the last graph don't intersect and are parallel, it has no solutions. Hope this helps :))
<span>If the Venn diagram
shows a universe with 26 elements and two different outcomes which are B and Y,
then the probability will be 7/6. The correct answer to the following
given statement above is seven over six or 7/6.</span>
So represent the ages as x y and z with each being numbers
x+y+z=21
x times y times z=75
this is really tough for elementary school
one way is to find the factors of 75 or the numbers that add up to 75 and trial and error
use whole numbers becuase this is the world of math so
75=1 times 3 times 5 times 5
possible ages are
3,5,5
1,5,15
1,3,25
add them up
3+5+5=13
1+5+15=21 check
1+3+25=29
their ages are 1, 5 and 15
