Help me out please!! For what value of X must ABCD be a parallelogram?

Mathematics
1 answer:
Darina [25.2K]2 years ago
3 0

Answer:

x = 3

Step-by-step explanation:

A parallelogram must have two pairs of parallel sides.

For this to be true, the alternate exterior angles of the diagonal must be congruent.

Hence the equation,

<u>10x + 4 = 13x - 5</u>

Simplify.

<u>9 = 3x</u>

<u>x = 3</u>

A customer placed an order with a bakery for cupcakes. The baker has completed 37.5% of the order 81 cupcakes. How many cupcakes
Paul [167]

Answer:

The total number of cupcakes ordered=216

Step-by-step explanation:

The total number of cupcakes ordered that the baker completed can be expressed as;

C=P×t

where;

C=Total number of completed order of cupcakes

P=percentage of order completed

t=total number of ordered cupcakes

In our case;

C=81

P=37.5%

t=t

replacing in the above expression;

81=37.5%×t

(37.5/100)×t=81

t=81×100/37.5

t=216

The total number of cupcakes ordered=216

I just need help for 3 questions!
Lelechka [254]
Answers: 
1. a) 4.1x + 29
2. b) 1/5(m – 100)
3. c) nine over five y + 9 (9/5y + 9)

Explanations:
1. The formula for perimeter of a triangle is P = side a + side b + side c, so with these values it is:
2.3x + 14 + 2x – .2x + 15 
Combine like terms:
4.1x + 29
2. Test the options to see which ones work out to the answer. You know that 1/5 of 100 = 20, so you need one with a 100 and a 1/5 in it. The only possible answer is:
1/5(m – 100)
3. Distribute the 3/5:
3/5 • 3y + 3/5 • 15 = 9/5y + 45/5 = 9/5y + 15
