Answer:

you first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.

Answer:

PART 2,4,6 are not solvable since they do not have any number

Part 1

1 = 61

2 = 119

3 = 61

4 = 119

5 = 61

6 = 119

7 = 61

8 = 119

Part 3

1 = 128

2 = 52

3 = 128

4= 52

5 = 128

6 =52

7 = 128

8 =52

Part 5

1 = 135

2 = 45

3 = 135

4 = 45

5= 135

6= 45

7=135

8= 45

$proof: \: 3(5x + 1) = 13x + 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 15x + 3 = 13x + 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (15x - 13x) + 3 = 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2x = (5 - 3) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2x = 2 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: x = (2 \div 2) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: x = 1$

What are the solution(s) to the quadratic equation 50 – x2 = 0? x = ±2 x = ±6 x = ±5 no real solution btw i just clicked the las

bagirrra123 [75]

50-x^2=0
Move the x^2 to the other side
x^2=50
Now take the square root of both sides
x=+_(50)^1/2 (^1/2 means square root)(+_ is plus or minus. Sorry XD)
Now simplify the square root
X=+_5(2)^1/2
Voila. The answer is C
