5 0

Answer: Her final score is negative 1.

Step-by-step explanation:

She started off with a score of 0, then gained 4. So you would add 4 to zero. Then, she lost 8 points so you would subtract 8 from her current score of 4, making the new total negative 4. Last, she gained three more points so you would add 3 to -4, giving you the final answer of -1.

4 - 8 = -4

-4 + 3 = -1

Multiplying a number by 2 and then dividing it by 3 is the same as multiplying by what number

dybincka [34]

2*6= 12 divided by 3 is 4.

2*2= 4

So multiplying 6 by 2 and then dividing by 3 is the same as multiplying 2 by 2.

Two trains 100 km apart are traveling toward each other along the same track. The first train goes 50 km per hour; the second tr

dem82 [27]

Answer:

92.31 km

Step-by-step explanation:

Combined speed = 50+80

= 130 km/hour

Time = 100/130 = 10/13 hours to collide

Speed × time = distance

distance = 10/13 × 120

= 92.30769231 km

Solve this equation for x: 2x^2 + 12x - 7 = 0

zhannawk [14.2K]

Answer:

x=0.5355 or x=-6.5355

First step is to: Isolate the constant term by adding 7 to both sides

Step-by-step explanation:

We want to solve this equation: $2x^2 + 12x - 7 = 0$

On observation, the trinomial is not factorizable so we use the Completing the square method.

Step 1: Isolate the constant term by adding 7 to both sides

$2x^2 + 12x - 7+7 = 0+7\\2x^2 + 12x=7$

Step 2: Divide the equation all through by the coefficient of $x^2$ which is 2.

$x^2 + 6x=\frac{7}{2}$

Step 3: Divide the coefficient of x by 2, square it and add it to both sides.

Coefficient of x=6

Divided by 2=3

Square of 3= $3^2$

Therefore, we have:

$x^2 + 6x+3^2=\frac{7}{2}+3^2$

Step 4: Write the Left Hand side in the form $(x+k)^2$

$(x+3)^2=\frac{7}{2}+3^2\\(x+3)^2=12.5\\$

Step 5: Take the square root of both sides and solve for x

$x+3=\pm\sqrt{12.5}\\x=-3\pm \sqrt{12.5}\\x=-3+ \sqrt{12.5}, $ or $x= -3- \sqrt{12.5}\\$x=0.5355 or x=-6.5355$

Sonia has three bracelets. she wears them all at the same time but if a different order each day. how many different combination

astraxan [27]

We can use a factorial to solve this:

3! = 3 * 2 * 1 = 6

So, she can wear them in a total of 6 combos.
