Answer:
square root 162
Step-by-step explanation:
Answer:
The system of equations are;
4.75t + 7.50b = 790
t = 2b
where t is the number of tacos and b is the number of burritos
Step-by-step explanation:
In this question, we are concerned with writing the system of equations that could help us determine the number of tacos and burritos sold.
Firstly, we start with defining variables. Let the number of tacos sold be t and the number of burritos sold be b
*there we twice as many burritos as tacos sold. What this simply means is that the number of tacos sold is twice the number of tacos.
Mathematically that could be written as ;
t = 2b ••••••••••(i)
Now, let’s work with the revenue;
Each taco is sold at $4.75 and he sold a total of t tacos. The revenue realized from tacos sold is thus $4.75 * t = $4.75t
The money realized from selling b burritos at $7.50 each would be $7.50 * b = $7.50b
The addition of both of these will give the total revenue of $790
Thus, we have;
4.75t + 7.50b = 790 ••••••• (ii)
Sec(theta) = 1.3591392 => cos(theta) = 1 / 1.3591392 = 0.7357598103
=> theta = arccos (0.7357598103) = 0.744 rad = 42.6285 degress
Answer: x=−3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−4)+3x−9x=6−(2x+5)+8x
(5)(x)+(5)(−4)+3x+−9x=6+−2x+−5+8x(Distribute)
5x+−20+3x+−9x=6+−2x+−5+8x
(5x+3x+−9x)+(−20)=(−2x+8x)+(6+−5)(Combine Like Terms)
−x+−20=6x+1
−x−20=6x+1
Step 2: Subtract 6x from both sides.
−x−20−6x=6x+1−6x
−7x−20=1
Step 3: Add 20 to both sides.
−7x−20+20=1+20
−7x=21
Step 4: Divide both sides by -7.
−7x over -7
=
21 over -7
x=−3
