Lines AD and BC are parallel.

allochka39001 [22]

*see attachment for the missing figure

Answer:

Angle ADE = 45°

Angle DAE = 30°

Angle DEA = 105°

Step-by-step explanation:

Since lines AD and BC are parallel, therefore:

Given that angle Angle CBE = 45°,

Angle ADE = Angle CBE (alternate interior angles are congruent)

Angle ADE = 45° (Substitution)

Angle DAE = Angle ACB (Alternate Interior Angles are congruent)

Angle ACB = 180 - 150 (angles on a straight line theorem)

Angle ACB = 30°

Since angle DAE = angle ACB, therefore:

Angle DAE = 30°

Angle DEA = 180 - (angle ADE + angle DAE) (Sum of angles in a triangle)

Angle DEA = 180 - (45 + 30) (Substitution)

Angle DEA = 180 - 75

Angle DEA = 105°

At the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. Three cheeseburgers and two

Svetlanka [38]

Answer: 290 calories in a cheeseburger and 230 calories in fries.

x = calories in a cheeseburger

y = calories in an order of small fries

Four cheeseburgers and five small fries have 2,310 calories. Therefore

4x + 5y = 2310 (1)

Three cheeseburgers and two small fries have 1,330 calories. Therefore

3x + 2y = 1330 (2)

Equations (1) and (2) model the given situation.

To solve, multiply (1) by 2, and multiply (2) by 5 to obtain

 8x + 10y = 4620 (3)

15x + 10y = 6650 (4)

Subtract (3) from (4).

7x = 2030

x = 290

From (1), obtain

5y = 2310 - 4*290 = 1150

y = 230

 x = 290, y = 23

Hope this helps!

DIVIDE. (4x4 - 8x3 + 4x - 8) / (4x - 8)

svetoff [14.1K]

Answer:

x³+1

Step-by-step explanation:

4x-8 | 4x⁴ - 8x³ + 4x - 8

_4x⁴ - 8x³______ <-- x³

4x - 8

4x - 8 <-- 1

0 | x³+1

Therefore, (4x⁴-8x³+4x-8)/(4x-8) = x³+1
