Answer:
Answer: x= -6 and y= -7
Step-by-step explanation:
Substitute 2x+5 for y in y=3x+11:
y=3x+11
2x+5=3x+11
2x+5+−3x=3x+11+−3x(Add -3x to both sides)
−x+5=11
−x+5+−5=11+−5(Add -5 to both sides)
−x=6
−x−1=6−1(Divide both sides by -1)
x=−6
Step: Substitute −6 for x in y=2x+5:
y=2x+5
y=(2)(−6)+5
y=−7(Simplify both sides of the equation)

Answer:
They should increase their price by $28.
Step-by-step explanation:
First find out what 35% of 80 is. Do so by multiplying 80 by 35% in its decimal form - .35.
80*.35=28.
This means that they have to increase their price by at least 28 dollars to make a profit.
The new price of the instrument should be $108 - $80 increased by 35%.
Hope this helps :)
Answer:
4.082 radians
Step-by-step explanation:
Here we want to convert 234° into radians.
To do it, we use the fact that pi radians is equal to 180°
Then we can write two equations:
x radians = 234°
3.14 radians = 180°
Where we want to find the value of x, which is the equivalent in radians to 234°.
Now we can take the quotient of these two equations to get:
( x radians)/(3.14 radians) = (234°/180°)
Solving this for x, we get:
x radians = (234°/180°)*(3.14 radians) = 4.082 radians.
