2x=2. Solving this, you get x=1. You then add 2 to 1 because she already has 2 necklaces to get that she can have a total of 3 necklaces.
Answer:
3

x+2y=10 2x-3y=-9
Solution of the system:
or as ordered pair: (2, 4)
Remember that the point of intersection of two lines is the solution of the system of linear equations. We know from our graph that our lines intersect at the point (1.7, 4.1), so the solution of our system of linear equations is (1.7, 4.1).
Now, to obtain the nearest integer of a decimal, we focus on the number after the decimal point: if the number is five or bigger than five, we add 1 to our integer; if the number is less than five, we keep the integer as it is.
For 1.7
The number after the decimal point is 7. Since 7 is bigger than 5, we add 1 to our integer, so the nearest integer of 1.7 is 2
For 4.1
The number after the decimal point is 1. Since 1 is less than 5, we keep our integer as it is, so the nearest integer of 4.1 is 4

What is RS?
4 feet
7 feet
10 feet
14 feet
Answer:
B. 7 feet
Step-by-step explanation:
Given:
NS = (x + 10) ft
SR = (x + 3) ft
Required:
RS
SOLUTION:
Based in the centroid theorem, the centroid, S will divide the median, line segment NR, into NS and SR, such that NS : SR = 2 : 1.
Therefore:
NS = 2(SR)
x + 10 = 2(x + 3) (substitution)
Solve for x
x + 10 = 2x + 6
Collect like terms
x - 2x = -10 + 6
-x = -4
divide both sides by -1
x = 4
SR = (x + 3) ft (SR is same as RS)
Plug in the value of x
SR = (4 + 3) ft
SR = RS = 7 ft
