Solve using elimination.<br> 2x – 4y = 10<br> -3x + 4y = -19
Darina [25.2K]

Answer:

x= 9 y=2

Step-by-step explanation:

Add up the equations vertically to eliminate y.

-x=-9

change the signs:

x=9

substitute the given value of x into the equation 2x-4y=10

2(9)-4y=10

18-4y=10

4y=8

y=2

Find the surface area of the following figures.<br><br>with solution please. T-T​​
Airida [17]

Answer:

1.a=5cm

Surface area :6a²=6×5²=150cm²

2.r=3cm

h=5cm

total surface area of cylinder =2πr(r+h)

=2π×3(3+5)=48π cm²

3.

l=4m

b=5m

h=2m

now.surface area =2(lb+lh+bh)

=2(4*5+4*2+5*2)

=76m²

4.

r=6cm

surface area =4πr²=4*π*6²=144πcm²

5.

slant height (S)=8cm

length =breadth=(L)=4cm

Surface area of pyramid =area of base + 2* area of trainglular face

=L²+2*S*L

=4²+2*8*4

=80cm²
