To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical.

Graph the system of equations on a graph paper.

inysia [295]

Answer:

Step-by-step explanation:

8x + 6y = 48.....reduces to 4x + 3y = 24

2x - 3y = -6

4x + 3y = 24

-------------------add

6x = 18

x = 18/6

x = 3

2x - 3y = -6

2(3) - 3y = -6

6 - 3y = -6

-3y = -6 - 6

-3y = -12

y = -12/-3

y = 4

solution is : (3,4)

the ordered pair (3,4) lies in quadrant I

the x coordinate of the solution is 3

the y coordinate of the solution is 4

Alexa wants to have a bowling average of at least 210. If her scores are 230, 185, and 195, what does she need to score on her f

Aleks04 [339]

Step-by-step explanation:

so her minimum 4th score is calculated this way:

$\frac{230 + 185 + 195 + x}{4} = 210 \\ 610 + x = 840 \\ x = 230$

so in round four

her score should be x in the way that:

x≥230
