Answer:
The Second choice y+5=-3/4(x-2
Step-by-step explanation:
4y=3x+8 solve for y so it's y=-3/4x+2
and use the slope which is -3/4
2 = x then 5 = y
you used to pass through formula and plug it in soooo it's
y+5=-3/4(x-2)
sorry if this doesn't make any sense, I'm terrible at explaining
Answer: 30
Step-by-step explanation:
If you notice that multiplying by 0.5 is the same as dividing by 2, all you need to do is multiply 18 by 2, giving you 36, then subtract 6 from that, therefore giving you 30 as the answer
The answer is 0.690129 hope this helps:)
Reading through the problem we have <em>3 is</em>, that's <em>3 equals</em>, <em>what percent</em>, <em>x/100</em>, <em>of 600</em>, <em>times 600</em>.
Notice that for <em>what percent</em> I put <em>X</em>/100. The reason I did this is because the word percent means over 100 and since we don't know what percent we're dealing with yet, we can put a variable there as a placeholder.
So we have 3 = <em>X</em>/100 · 600.
Now cross-canceling the 600 and 100 to 6 and 1, we have 3 = 6x/1.
Multiply both sides by 1 to get rid of the fraction and we have 3 = 6x.
Dividing both sides by 2, we find that 0.5 = x.
So <em>3 is 0.5% of 600</em>.
