Y=2x+5 and y=3x+11 solve by substitution.
kondaur [170]

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)

A music store buys a trumpet for $80. They want to make a 35% profit. How much are they going to increase the price?
elena-s [515]

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 :)

How many radians is 234°?<br> Give the exact answer in simplest form.
prohojiy [21]

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.
