Ksenya-84 [330]

Answer:

11 invitations each

Step-by-step explanation:

Since they spent the same amount of money, Their total costs would be the same. Hence ;

3.25 + 0.75(x) = 0.5x + 6

0.75x - 0.5x = 6 - 3.25

0.25x = 2.75

x = 2.75/0.25

x= 11 invitations

Use the figure below to complete the following problem. Given: H = 2x + 60 T = x + 30 HALT is a ∠H = 90 120 150
Pavlova-9 [17]

Answer:

∠H = 120

Step-by-step explanation:

See the attached figure

HALT is a parallelogram

So, angles H and T are supplementary.

∠H = 2x + 60  and ∠T = x + 30

∠H + ∠T = 180

∴ 2x + 60 + x + 30 = 180

∴ 3x + 90 = 180

∴ 3x = 180 - 90 = 90

∴ x = 90/3 = 30

So, ∠H = 2x + 60 = 2 * 30 + 60 = 60 + 60 = 120
