6n + 15 = -42. If you wish to go further and find n, then subtract 15 from both sides, obtaining 6n = -57, so that n = -57/6.
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:
w = π/2
Step-by-step explanation:
I used trig identities (double angle) to solve this problem.
Step 1: Rearrange problem
2cos²(w) - cos(w) - 1 = 0
2cos²(w) - 1 - cos(w) = 0
Step 2: Trig Identity
cos2w - cos(w) = 0
Step 3: Combine like terms
cosw = 0
Step 4: Solve
w = cos^-1(0)
w = π/2
I may have done it wrong so don't rely too much on me
It is (positive) five. divide -1.25 by -0.25.
The question asks to convert the current decimal number into a fraction in simplest form and the possible answer, base on my ways nad calculating the said decimal, its fractional form is 1/16.
