Answer:
X= 4.2
Step-by-step explanation:
To get x by itself all you have to do is divide both sides by 3 and 12.6 divided by 3 is 4.2
Answer:
V=282.74in^3
Step-by-step explanation:
Volume of cylinder
V= TTr^2h
Where
TT=3.14
r=3
h=10in
V=3.14*3^2*10= 282.743in^3
Answer:
<u>Solve each inequality and combine solutions:</u>
- 3x - 10 < 0 ⇒ 3x < 10 ⇒ x < 10/3
- 2x > 0 ⇒ x > 0
<u>Combination of the two is:</u>
or
Answer:
Step-by-step explanation:
Because the trapezoid is isosceles, the two diagonals are congruent. This can be shown by ASA.
ACD = BDC Properties of parallel lines.
DC = DC A line is equal to itself
DBA = CAB Property of parallel lines.
AC = DB Parts of Congruent triangles are congruent
3x + 15 = 7x - 9 Add 9 to both sides
3x + 15 + 9 = 7x
3x + 24 = 7x Subtract 3x from both sides.
24 = 7x - 3x
24 = 4x Divide by 4
24/4 = 4x/4
x = 6
The correct answer is (A)!
