a) 6x - 5y = 10x + 7 SOLVING FOR X:
6x-5y=10x+7
−5y=10x+7−6x
−5y=4x+7
−5y−7=4x next divide both sides by four and switch sides
a) 6x - 5y = 10x + 7 SOLVING FOR Y:
6x-5y=10x+7
−5y=10x+7−6x then simplify
−5y=4x+7, now divide both sides by negative five
b) -4 +(-3) -(-9)
-4+(-3)-(-9) Remove parentheses and simplify.
−4−3+9=−7+9=2
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

Answer:
10 metal and 20 plastic
Step-by-step explanation:
10 x 25 is 250, 20 x 10 is 200 and 250 + 200 is 450
The slope is 0, it is a straight line.
Hope this helps!
The 11/2 cup of black beans is extraneous info, you just need to know that it provides 15% of the potassium you need daily. With that info, you know that you need 85% more to fulfill your daily value. If we say x is the total amount of potassium needed, then we can set up the equation:
x * 0.85 = 2890
Then we can solve for x by dividing both sides by 0.85. The answer, then, is 2890/0.85 = 3400 mg.
