Answer:
Step-by-step explanation:
2x+5y=12
3x+4y=11
---------------
3(2x+5y)=3(12)
-2(3x+4y)=-2(11)
-----------------------
6x+15y=36
-6x-8y=-22
-----------------
7y=14
y=14/7=2
2x+5(2)=12
2x+10=12
2x=12-10=2
x=2/2=1
x=1, y=2. (1, 2)

I just provided you an example of a system of equations and I already solved it for you.
<span>Joe got an hourly raise at work and his new rate will be $10.25 per hour.
</span>If r represents the amount of the raise, then the following equation can be written:
X=10.25-r
where X is <span>Joe’s hourly rate was before his raise.
Joe was paid (10.25-r) USD per hour before he got a raise.</span>

Answer:
Blues Paints = 2.45 pints
Step-by-step explanation:
Let's generate an expression that would relate all the variables given:
Total pints of paints used:
9.8 = white + blue
Pints of white paint used:
= 3/4 of 9.8
=0.75 * 9.8
=7.35
Number of pint of BLUE PAINTS used:
9.8 = White Paints + Blue Paints
9.8 = 7.35 + Blue Paints
Blue Paints = 9.8 - 7.35
Blues Paints = 2.45
Kate used 2.45 pints Blues Paints for her bedroom
