He's another way
4+2 evaluate to 6 multiply 3 and 6

3*(4+2) evaluate to 18
2-3*(4+2) evaluate to -6

Solve for x Urgent need help

fiasKO [112]

I believe you need to solve this using the quadratic formula!
To begin, this is what it is:
x= -b ± √ b^2 - 4ac / 2a
Just plug in what you have in your problem...
2 being a, 13 being b, and -24 being c.
So we get:
x= -13 ± √13^2 - 4(2)(-24) / 2(2)
x= -13 ± √169 - 8 (-24) / 4
x= -13 ± √169 + 192 / 4
x= -13 ± √361 / 4
The square root of 361 is 19.
So you have: -13 ± 19 / 4.
Here's where you take the equation -13 ± 19 and put the addition and subtraction sign to use.
-13 - 19 = -32
and
-13 + 19 = 6
Now all is left to do is divide the two numbers by 4.
-32/4 = -8
and
6/4 = 3/2

x = -8, 3/2

Translate to a system of equations:

omeli [17]

Answer:

m + n = 15

m - 3 = n

The numbers are 9 and 6

Step-by-step explanation:

From the question,

The sum of two numbers is fifteen; the first number is m and the second number is n. To translate to a system of equations, we can write that

m + n = 15 ..... (1)

Also, from the question,

One number is three less than the other,

Also, to translate to a system of equations, we can write that

m - 3 = n ...... (2)

If desired, we can determine m and n

From equation (1)

m + n = 15

Then,

m = 15 - n ...... (3)

Put the value of m in equation (3) into equation (2)

m - 3 = n

Then

15 - n - 3 = n

15 - 3 = n + n

12 = 2n

n = 12/2

∴ n = 6

For m, put the value of n into equation 3

m = 15 - n

m = 15 - 6

m = 9

∴ m = 9 and n = 6

Hence, the numbers are 9 and 6

Amelia and Joey decided to shoot arrows at a simple target with a large outer ring and a smaller bull's-eye. Amelia went first a

Alona [7]

Answer:

outer ring worth 14 pts

bull's-eye worth 74.333333 pts

Step-by-step explanation:

let the worth point of landing an arrow on the outer ring be "x" and on bull's eye be "y"

For amelia

$3x + 3y = 267$

For joey

$4x + 3y = 281$

subtracting the first equation from the second

$x = 14$

$3x + 3y = 267$

$42 + 3y = 267$

$3y = 223$

$y = 74.333$
