X=2 here’s why 90-32 is 58. 29x=58 then x is 2
I don’t believe it is factorable
7p+5p
When you combine like terms, you just add all the terms that have the same variable so you get:
12p
<span>Estimate
</span>44,596,251 = <span>45,000,000
</span>28,257,934 = <span>28,000,000
</span>45,000,000 - 28,000,000 = 17,000,000
answer
17,000,000
<em>x</em> = liters of 1% solution
<em>y</em> = liters of 5% solution
<em />
<em>x</em> + <em>y</em> = 16
0.01<em>x</em> + 0.05<em>y</em> = 0.04*16 = 0.64
<em />
<em>y</em> = 16 - <em>x</em>
<em />
0.01<em>x</em> + 0.05(16 - <em>x</em>) = 0.64
0.01<em>x</em> + 0.8 - 0.05<em>x</em> = 0.64
0.16 = 0.04<em>x</em>
<em>x</em> = 4
<em>y</em> = 12
