Mathematics
1 answer:
Viktor [21]3 years ago
8 0

Answer:

x = 4

Step-by-step explanation:

DE is parallel to AC and intersects the other 2 sides. It divides those sides proportionally, that is

\frac{BD}{DA} = \frac{BE}{EC}, thus

\frac{10-x}{x} = \frac{3}{2} ( cross- multiply )

2(10 - x) = 3x ← distribute left side

20 - 2x = 3x ( subtract 3x from both sides )

20 - 5x = 0  ( subtract 20 from both sides )

- 5x = - 20 ( divide both sides by - 5 )

x = 4

A hockey bag contains 5 red jerseys, 6 blue jerseys and 7 white jerseys.
ipn [44]

Answer:

7/54

Step-by-step explanation:

A hockey bag contains 5 red jerseys, 6 blue jerseys and 7 white jerseys.

Let the total number of jerseys =

5 red jerseys + 6 blue jerseys 7 white jerseys.

= 18

P(White) = 7/18

P(Blue) = 6/18

Hence, the probability that Jack picks a white then a blue jersey if he puts the first one back.

This is probability with replacement, hence:

7/18 × 6/18

= 7/18 × 1/3

= 7/54

Question in pic, will mark brainliest.
bulgar [2K]

Answer:

See explanation

Step-by-step explanation:

Consider triangles ABC and DEC. In these triangles,

  • \overline{BC}\cong \overline {EC} - given
  • \overline{AC}\cong \overline {DC} - given;
  • \angle ACB\cong \angke DCE as vertical angles.

So,

\triangle ABC\cong \triangle DEC by SAS postulate (two sides and angle between these sides of one triangle are congruent to two sides and angle between these sides of another triangle, so triangles are congruent).

Congruent triangles have congruent corresponding parts, hence,

\overline{BA}\cong \overline{ED}
