Answer:
x=17
Step-by-step explanation:
3x-24=x+10
Carry over the like terms and put them together. Make the unknowns which are x the subject.
3x-x= 24+10
2x= 34
2x= 34/2
x= 17
1,099 square inches.
formula for surface area of cylinder:
2 π r^2 + 2 π rh
π = 3.14
Use formula with given dimensions:
2 • 3.14 • 5^2 + 2 • 3.14 • 5 • 30 = 1,099
Final answer: 1,099 square inches
(NOT ROUNDED)
Have a nice day!
Find the circumference:
Circumference = 2 x pi x radius
Circumference = 2 x 3.14 x 9 = 56.52 inches
the arc length is 45 degrees/360 degrees of the circumference.
Marc length = 56.52 x 45/360 = 7.065 inches
Rounded to the nearest tenth = 7.1 inches
Answer:
( 
, - 
)
Step-by-step explanation:
given the 2 equations
2x + 3y = - 4 → (1)
4x - y = 11 → (2)
Rearrange (2) expressing y in terms of x, that is
y = 4x - 11 → (3)
Substitute y = 4x - 11 into (1)
2x + 3(4x - 11) = - 4
2x + 12x - 33 = - 4
14x - 33 = - 4 ( add 33 to both sides )
14x = 29 ( divide both sides by 14 )
x =
Substitute this value into (3) for corresponding value of y
y = (4 × ) - 11 = 
- 
= - 
= -
solution is ( , - )
Convert the mixed number into an improper fraction 10/3 now turn the denominator into 6
10/3× 2/2 = 20/6
there are 20 sixths in 3 1/3
