Answer:
Step-by-step explanation:
11x^{2}+x^{2}=\left(4x+8\right)\left(3x-3\right)
(x)+(x)+(x+4)+(x+4)= (x)+(x+9)+(x+5) *add like term*
4x+4=3x+14 *subtract 3x from both sides*
x+4=14 subtract 4 from each side
x=10
Alright, to average 1000 per day over 3 days, we have 1000*3=3000 dollars. Since we already have 2 days, we do 3000-1240-921=839
Answer:
y=12°
x= 20°
Step-by-step explanation:
5y=60
y=60/5=12
3x+60+60=180
3x=180-120=60
x=60/3=20
Answer:
The measure of angle T is 135 degrees.
Step-by-step explanation:
Let's just say the measure of angles T and S are variables t and s.
So the equation would be...
t + s = 180
Since they are supplementary angles, they add up to 180.
Also, we know that t is 3 times s.
t = 3s
Now we can solve this system of equations.
Substitute 3s into t of the first equation.
3s + s = 180
4s = 180
s = 45
Then, since we know that the measure of angle t is 3 times the measure of angle s, we can just multiply 45 by 3 and find the measure of angle t.
45 * 3 = 135
t = 135
So the measure of angle t is 135.
