Answer:
Jana had 8 oranges, and Jordan had 15 oranges.
Step-by-step explanation:
First, identify what you know:
1) In total, Jana and Jordan had 23 oranges.
2) Jana had 7 less oranges than Jordan.
We can create a formula, where x equals the number of oranges Jana has.
23 = x + (x + 7)
16 = x + x (subtracted 7 from both sides)
x = 8 (divided both sides by 2)
So, now we know Jana had 8 oranges, which is 7 less than Jordan.
8 + 7 = ?
? = 15
Jana had 8 oranges, while Jordan had 15, for a total of 23 oranges.
Answer:
h
Step-by-step explanation:
square root of 260 is 16.1 therefore h is the closest
Answer:
This is an identity or infinite solutions
Step-by-step explanation:
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
10x - 12y = 22
0=0
Identity solution
Answer:
x = ±2sqrt(2)
Step-by-step explanation:
x^2 = 8
Take the square root of each side
sqrt(x^2) = ±sqrt(8)
x = ±sqrt(4*2)
We know that sqrt(ab) = sqrt(a)sqrt(b)
x = ±sqrt(4)sqrt(2)
x = ±2sqrt(2)
