The answer would look something like this:

$\frac{2+-\sqrt{2^{2}-4(-3)(6) }}{2(-3)}$

There could also have a simplified version.

I hope this helps.

Describe how you regroup when you find the sum of 64+43

damaskus [11]

Here, regrouping is basically carrying.

64+43 shown vertically would be:

64
+43
-------
107
4+3 is 7, so seven is in the ones place, but that's not the point.
60+40 is 100, so you regroup by carrying the one to the hundreds place.

Hope I helped!

Find a rational number halfway between 7/8 and 6/7

algol [13]

<h3>Answer: 97/112</h3>

================================================

How to get this answer:

Midpoint formula: (A+B)/2 = C

A and B are the endpoints with C as the midpoint

A = 7/8

B = 6/7

A+B = 7/8 + 6/7

A+B = 49/56 + 48/56

A+B = (49+48)/56

A+B = 97/56

(A+B)/2 = (97/56) divided by 2

(A+B)/2 = (97/56) times (1/2)

(A+B)/2 = (97*1)/(56*2)

(A+B)/2 = 97/112

Guy wires 80 feet long support a 65-foot tall telephone pole. to the nearest degree, what angle will the wires make with the gro

Usimov [2.4K]

Answer: The guy wires will make a 54 degree angle with the ground.

Start by drawing a right triangle. The hypotenuse will be 80 and the side opposite our angle will be 65.

Since we are working with the opposite side and hypotenuse, we can write and solve the sin equation below.

Sin(X) = 65/80 (Take the inverse sign of both sides)
x about 54 degrees

Dylan has a bank that sorts coins as they are dropped into it. A panel on the front displays the total number of coins inside as

romanna [79]

Answer:

Dylan will not have enough money. He needs $22.65 but only has $22.50

Step-by-step explanation:

If Dylan's mom replaces each dime with a quarter, then Dylan will have 90 quarters.

1 Quarter = $0.25

90 x .25 = $22.50

The game costs $20.98 plus 8% sales tax

So 20.98 x .08 = $1.6784

20.98 + 1.6784 = $22.65

Dylan will not have enough money because he only has $22.50 when he needs $22.65
