Answer:

X=3

Step-by-step explanation:

2(4x-3)-t=4+2x

multiply parentheses by 2

8x-6-8=4+2x

Calculate

8x-14=4+2x

Move terms

8x-2x=4+14

Calculate the sum after collecting like terms

6x=18

Divide both sides by 6

x=3

Answer:

Step-by-step explanation:

2(4x − 3) − 8 = 4 + 2x

2 • 4x = 8x

2•-3=-6

8x-6= 4+2x

get x by itself

x=3

Answer:

2.85 × 10^7

Step-by-step explanation:

1.In scientific notation, the whole number before the decimal point shouln't be more than 10(exclude 10) or less than 1(include 1)

2.Count the digits after the decimal point to write the power.

Solution;

1. 2.85( 2 is not less than 1 as well as more than 10).

2.Since there are 7 digits after the decimal point, we should write the power 10^7.

3. Complete answer;

Emma is playing miniature golf. Her ball is 2 feet to the left of the right-hand wall. The hole is 4 feet to the left of the wal

NISA [10]

Answer:

She should aim 6 feet down the wall

Explanation:

The diagram attached sketches the situtation.

Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.

Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:

x/4 = y/2 ⇒ x = 2y

You have other equation:

x+ y = 18

Substitute

2y + y = 18
3y = 18
y = 18/3
y = 6 ← this is the distance down the wall where the ball should hit

x = 2(6) = 12

Then, she should aim 6 feet down the wall.
