Correct Question:

5 (u + 1) - 7  = 3 (u - 1) + 2u.

Solve for u

Answer:

See explanation below

Step-by-step explanation:

In this given question, we are required to find u.

Given the equation:

5 (u + 1) - 7 = 3 (u - 1) + 2u​

Required:

Solve for u

To find u, first simplify both sides individually.

Simply 5 (u + 1) - 7:

Expand the parenthesis:

5u + 5 - 7

Collect like terms:

5u - 2

<em>Simplify 3 (u - 1) + 2u​:</em>

Expand the parenthesis:

3u - 3 + 2u

Collect like terms:

3u + 2u - 3

5u - 3

Bring both simplified equations together:

5u - 2 = 5u - 3

5u - 5u - 2 = -3

-2 = -3

Since -2 ≠ -3, there is no solution.

Therefore, we can say the equation is invalid.

******ANSWER ASAP PLEASE******
Lemur [1.5K]

(1/4)^-2 - (5^0 x 2) x 1^-1 =

(4/1)^2 - (1 x 2) x 1 = 16-2 = 14

If you raise something to the power of -2, swap numerator and denominator and remove the minus.

So (1/4)^-2 = 4^2 = 16

Also 1^-1 is just 1, not -1.

Hitman42 [59]

Answer:

tan a + cot b

Step-by-step explanation:

It's already simplified.

There are alternate forms like

sec(a)csc(b)cos(a-b)\\\\sec(a)csc(b)[sin(a)sin(b)+cos(a)cos(b)]\\\\\frac{sin (a)}{cos (a)} +\frac{cos(b)}{sin(b)}

For tournament 50 people are put int teams 35 people are picked to play rugby and 15 are picked to play football what percentage
kvasek [131]

Answer: 30%

Step-by-step explanation:

Total number of people involved in the tournament= 50

Number of people chosen to play rugby= 35

Number of people chosen to play football= 15

To get the percentage of people that are chosen to play football, we divide the number of people chosen to play football by the total number of people chosen for the tournament and then multiply the answer by 100. This will be:

= 15/50 × 100

= 0.3 × 100

= 30%

The percentage of people chosen to play football is 30%.
