Answer:
m = -3 and b = 5
Step-by-step explanation:
y = -3x + 5
.......
Answer:
a) 5x=8 use a calculator and use distributive property
b) 22=3x+5 -18
22=3x-13
9=3x
x=3
distributive property
c)-48= -8x-20+5x-1
-48= -3x-21
-27= -3x
x=7
distributive property
Step-by-step explanation:
4/9 + (x-1) = 28/9 - (x-7x) + 1
4/9 + x - 1 = 28/9 - x + 7x + 1
-5/9 + x = 37/9 + 6x
-5x = 42/9
-5x = 4.6 (repeating 6)
x = -0.93 (repeating 3)
Hope this helps! ;)

I want to find the amount of antifreeze in a 15 quart solution with 30% antifreeze
<span><span>V<span>Antifreeze</span></span>=15∗0.30</span> =18/4 quarts of antifreeze
Similarly, I want to find the amount of antifreeze in a 15 quart solution with 35% antifreeze first.
<span><span>V<span>Antifreeze</span></span>=15∗0.35</span> = 21/4 quarts of antifreeze
<span>the difference between 21/4 and 18/4 is 3/4 quarts, which is the amount of pure antifreeze I've added in.
</span><span>
SO the V_fluid I replaced with 3/4 quarts of antifreeze is (3/4)/ 0.35</span>
