1.8c=7.5 \\\\ c=\frac{7.5}{1.8} \\\\ c=\frac{5\frac{5}{10}}{1\frac{8}{10}}=\frac{5\frac{1}{2}}{1\frac{4}{5}} \\\\ c=\frac{\frac{11}{2}}{\frac{9}{4}}= \frac{11}{2}*\frac{4}{9} \\\\ \boxed{c=\frac{22}{9}}

C= 4.166666... or C= 7.5/1.8
You need to get C alone so you divide 1.8 from 7.5.

Which equation represents a line with a slope of -2/3 that passes through point (5, -2)?
serg [7]

Answer:

c) 2x + 3y = 4

Step-by-step explanation:

−2 = −⅔[5] + b

−3⅓

1⅓ = b

y = −⅔x + 1⅓

Then convert to Standard Form:

y = −⅔x + 1⅓

+⅔x + ⅔x

__________

⅔x + y = 1⅓ [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

3[⅔x + y = 1⅓]

2x + 3y = 4

* 1⅓ = 4⁄3

29) Adam’s sister wants to watch her intake of fat per day. Here is a guideline of the recommended daily allowances. Typical val
ziro4ka [17]
Basically all the information in this problem is useless. They included all those numbers to confuse you. If you read throughly you can see that all you need to know is that Adam's sister can only have 70 grams of fat each day and that her dinner will have 48 grams of fat.

To figure this out I use this formula all the time to figure out percentages.
is/of=x/100
Your trying to figure out what is 48 percent of 70 because that's how much Adam's sister is going to eat at dinner. So your is would be 48 and your of is 70. When you substitute those numbers your formula becomes 48/70=x/100. Now you cross multiply and get 70x=4800.All that's left is to divide 70 on both sides. Which gives you 68.57.The final answer is 69 percent.
