Answer:

61

Step-by-step explanation:

A + B = 90

6 - 5x + 7 - 2x = 90

13 - 7x = 90

- 7x = 90 - 13

- 7x = 77

- x = 77 / 7

x = - 11

A: 6 - (5 * - 11) = 6 + 55 = 61

B: 7 - (2 * -11)  = 7 + 22 = 29

Together they equal 90 as they should.

A basketball team has won 50 games of 75
Alex73 [517]

Answer:

27 more games

Step-by-step explanation:

The team has played 75 games so far. Theyve won 50 out of 75 of those games. They still have 45 games left to play. That's 120 games in total. 60% of 120 is 72. They have to win 72 games in total. 72 - 45 = 27. They need to win 27 more games in order to have won 60% of all the games theyve played.

Simplify 10 - [14 = (3 + 4) · 2]+3
lora16 [44]

Answer:

There is a typo near the equal sign.

There can be two different answers if we think that = sign as + or -.

First way: Making = as +

=> 10 - [14 + (3+4) x 2] +3

=> 10 - [14 + 7 x 2] + 3

=> 10 - [14 + 14] + 3

=> 10 - 28 + 3

=> 10 + 3 - 28

=> 13 - 28

=> -15

=> So, -15 is the answer if we consider "=" sign as "+" sign.

Second way: Making = as -

=> 10 - [14 - (3+4) x 2] + 3

=> 10 - [14 - 7 x 2] + 3

=> 10 - [14 - 14] + 3

=> 10 - 0 + 3

=> 10 + 3

=> 13

=> So, 13 is the answer if we consider "=" sign as "-" sign.

Please give me an explanation too I need help Solve for y: 2x-y=3
harina [27]

Answer:

y = 2x -3

Step-by-step explanation:

to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3
