4x - 2y = 14
y = 1/2x - 1
4x - 2(1/2x - 1) = 14
4x - x +2 = 14
3x + 2 - 2 = 14 - 2
3x = 12
3x / 3 = 12/3
x = 4
2x = y -10
2x + 7 = 2y
y - 10 + 7 = 2y
y -y -10 + 7 = 2y - y
-3 = y
8x - 1/3 y = 0
12x + 3 = y
8x - 1/3y = 0
8x -1/3( 12x + 3) = 0
8x - 4x - 3 = 0
4x -3 + 3 = 0 + 3
4x / 4 = 3/4
x = 3/4
Answer:
$43.30
Step-by-step explanation:
What we know,
3 hamburgers = $12.99
Coleman wants to know how much would he have to pay for 10 hamburgers,
In order to find out how much 10 hamburgers cost, you need to find out how much 1 hamburger costs,
To find how much 1 hamburger costs divide 12.99 by 3,
12.99/3
= 4.33
Now we know that 1 hamburger cost $4.33,
Now time to find out how much 10 hamburgers cost,
Multiply 4.33 by 10,
4.33 × 10
= 43.30
Therefore it cost $43.30 for 10 hamburgers.
4y+25=3y+20
4y+5=3y
***y=5***
so you plug y into both
4(5)+25 and 3(5)+20
45, 100, and 35 are the measurements of the angles.
From the problem :
In multiplying expressions with the same bases, the exponent will be added accordingly.
For example :
the exponent of a are m and n, and the product will be a raised to the sum of m and n.
Applying this to the problem, we have :
The answer is d. 6^-1
