Answer:
9/12 and 10/12
Step-by-step explanation:
The LCD is the smallest number divisible by both 4 and 6, and that is 12.
Thus, 3/4 and 5/6 are equivalent to 9/12 and 10/12 .

Answer:
4x2 + 3x + 4
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 4 • 4 = 16
Step-2 : Find two factors of 16 whose sum equals the coefficient of the middle term, which is 3 .
-16+-1=-17
-8+-2=-10
-4+-4=-8
-2+-8=-10
-1+-16=-17
1+16=17
2+8=10
4+4=8
8+2=10
16+1=17
Final result :
4x2 + 3x + 4
The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Let x represent the number of tacos and y represent the number of burritos sold, hence:
x + y ≤ 120 (1)
Also:
4.75x + 7.5y > 690 (2)
and:
y ≥ 80 (3)
The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos

Answer:
Notebooks: $2.75 each; pens: $1.10 each
Step-by-step explanation:
Let n and p represent the unit cost of notebooks and the unit cost of pens.
Then 3n + 2p = $10.45, and 4n + 6p = $17.60.
Let's use elimination by addition/subtraction to find n and p.
Multiplying the first equation by -3, we get -9n - 6p = -$31.35
and then combine this with the second: 4n + 6p = $17.60
-----------------------------
Then, -5n = -$13.75
Dividing both sides by 55, we get n = $13.75 / 5, so we now know that n = $2.75. Each notebook costs $2.75.
Subbing $2.75 for n in the first equation, we get:
3($2.75) + 2p = $10.45, or
$8.25 + 2p = $10.45
Solving for p, we get p = $2.20 / 2 = $1.10.
Each pen costs $1.10.
