3*3=9 height
Answer:
1.75
Step-by-step explanation:
you have to make it an improper fraction first then subtract:)
Answer:
D
Step-by-step explanation:
well the anser has to equal 9 if you solved the question correctly BUT the other questions have to equal 9 so the first one is like this
(3*2-2)+(5*2+5*-1)
= (6-2)+(5*2+5*-1)
= (4)+(5*2+5*-1)
= 4+(5*2+5*-1)
= 4+(10+5*-1)
= 4+(10+-5)
= 4+(10-5)
= 4+(5)
= 4+5
= 9
Now the answers A is not it because
8*2+5*-3
= 16+5*-3
= 16+-15
= 16-15
= 1
B isnt it because
8*2+5*-1
= 16+5*-1
= 16+-5
= 16-5
= 11
And C isnt it because
2*2+5*-3
= 4+5*-3
= 4+-15
= 4-15
= -11
So that leaves D and this is how it is correct
= 8*2+7*-1
= 16+7*-1
= 16+-7
= 16-7
= 9
Hope this helps! Sorry I took so long
Answer:
First know this,
The volume V of a cylindrical barrel is given by the formula. V = πr2h, where r is the barrel's radius and h is the barrel's height.
Rewrite the equation as πr2h=V π r 2 h = V . Divide each term by πr2 π r 2 and simplify. Divide each term in πr2h=V π r 2 h = V by πr2 π r 2 .
Step-by-step explanation:
An identity is the same on both sides of the equals sign
C: 10p + 6 -p=12p-3(p-2)
9p +6 = 12p -3p +6
9p +6 = 9p +6
