You just add all the sides
X - the number
you double the number - 2x
you subtract the result from five - 5-2x
you get negative one - 5-2x=-1
The number is 3.
Answer:
volume from geometri always:
base area × h
if have peak point always:
1/3 × base area × h
the base of the pyramid in the figure is rectangle. then base from rect. is:
l × w
= 9 × 7
= 63
let get into formula: (use the second formula because pyramid has a peak point)
=1/3 × ba × h
=1/3 × 63 × 7
=21 × 7
=147 yd³
Answer:
x=3
Step-by-step explanation:
simplify both sides of the equation.
−34−7x=5(−5−2x)
−34+−7x=(5)(−5)+(5)(−2x)(Distribute)
−34+−7x=−25+−10x
−7x−34=−10x−25
add 10x to both sides.
−7x−34+10x=−10x−25+10x
3x−34=−25
add 34 to both sides.
3x−34+34=−25+34
3x=9
divide both sides by 3.
3x
3
=
9
3
x=3
