Answer:
(1, 2 )
Step-by-step explanation:
Given the 2 equations
- 2x - y = - 4 → (1)
x + 2y = 5 → (2)
Multiplying (2) by 2 and adding result to (1) will eliminate x- term
2x + 4y = 10 → (3)
Add (1) and (3) term by term to eliminate x
0 + 3y = 6
3y = 6 ( divide both sides by 3 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
x + 2(2) = 5
x + 4 = 5 ( subtract 4 from both sides )
x = 1
solution is (1, 2 )
Answer:
a) 23.5619449 m^2 b) 351.8583772 cm^2 c) 75.39822369 cm^2
Step-by-step explanation:
a):
SA = 2πr^2+2πr
r= 3/2 = 1.5
SA= 2π*1.5^2 + 2π*1.5
SA= 15/2 ∏
SA= 23.5619449 m^2 round it as you want
b): Same steps as "a" but rather than m^2 it is cm^2
the answer will be:
SA= 112π
SA= 351.8583772 cm^2 round it as you want
c): the radius is already given so just place it in place of r
SA= 2π*3^2 + 2π*3
SA= 24π
SA= 75.39822369 cm^2
Remember
area of paralellogram is height times legnth of base
7.
height=18.7
legnth of base=6
area=18.7*6=112.2 yd^2
8.
height=5
leggnth of base=6
aera=5*6=30 m^2
10.
flip on side
height=7
legnth of base=15.1
area=7 times 15.1=105.7 ft^2
11.
height=10.2
legnth of base=14.2
area=14.2 times 10.2=144.84 cm^2
13.
height=18
legnth of base=19
area=18*19=342 in^2
14.
height=18
legnth of base=18
area=18*18=324 mi^2
