Answer:

30. 2x²-x-1=0

or, 2x²-2x+x-1=0

or, 2x(x-1)+1(x-1)=0

or, (x-1)(2x+1)=0

so, x-1 = 0 or, x = 1

and 2x+1 = 0 or, 2x = -1 or, x = -1/2

so, x = 1 and 1/2

31. 3x²-14x=5

or, 3x²-14x-5=0

or, 3x²-15x+x-5=0

or, 3x(x-5)+1(x-5)=0

or, (x-5)(3x+1)=0

so, x-5=0 or, x=5

and 3x+1=0 or, 3x=-1 or, x=-1/3

so, x = 5 and -1/3

Oxana [17]

Answer:

x = 1

In basketball there are 1,2, and 3 point shots. In the last game sarah scored a total of 25 points by making 13 total baskets. S
ollegr [7]

Answer:

3 , 6 , 4

Step-by-step explanation:

Given:

There are three groups of shots in basketball.

First group carry = 1 point

Second group carry = 2 points

Third group carry = 3 points

Sarah scored a total of 25 points by making 13 total baskets.

She made twice as many 2 point shots as she did 3 point shots.

Question asked:

How many of each type of shot did she make ?

Solution:

Let number of baskets, she made which carry 3 points = x

Then, number of baskets, she made which carry 2 points = 2x

Total number of baskets, she made = 13

Then, number of baskets, she made which carry 1 points = 13-(x+2x)=13-3x

Now,

Sarah scored a total number of points = 25

3\times x+2\times2x+1(13-3x)=25\\3x+4x+13-3x=25\\4x+13=25

Subtracting both sides by 13

4x=25-13\\4x=12

Dividing both sides by 4

x=3

By substituting the value:-

Number of baskets, she made which carry 3 points = x = 3

Number of baskets, she made which carry 2 points = 2x = 2\times3=6

Number of baskets, she made which carry 1 points = 13-3x=13-3\times3=13-9=4

Thus, she made 3 baskets of 3 points, 6 baskets of 2 points and 4 baskets of 1 point.

ANOTHER FILL IN THE BLANKS QUESTION, MARKING BRAINLIEST FOR CORRECT ANSWER
Mamont248 [21]
Hi, again!
First blank: multiplication property of equality
Both sides of the equation were multiplied by (1/2). 

Second blank: m<E
Angle E is an inscribed angle intercepting arc FGD, so by the inscribed angle theorem, its measure is half the measure of the arc.

Third blank: m<G
Same explanation as the prior blank

Fourth blank: substitution property of equality
Since angle E is equal to half the measure of arc FGD, we can replace that term. Likewise with angle G.
