Answer:
$9
Step-by-step explanation:
These are given:
Total = 22
Cost for shoes = 4
Total games played = 2
Cost per game (g)= ?
So,
22 = 4 + 2(g)
-4 -4
18 = 2g
divide by 2
9 = g
$9 per game
Answer:
ax^2 + bx + c = 0
Here is a specific example:
5x^2 - 3x + 2 = 0
In other words:
You have zero on the right.
On the left, you have the powers of “x” in descending order.
The differnce of 2 perfect cubes
remember
a³-b³=(a-b)(a²+ab+b²)
so
Answer:
n - (-4) ≥ 10
4(n+5) ≥ 48
Step-by-step explanation:
n - (-4) ≥ 10
n + 4 ≥ 10
n ≥ 6
4(n+5) ≥ 48
4n + 20 ≥ 48
4n ≥ 28
n ≥ 7
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
