The sum of a student's three score is 246. if the first is 14 points more than the second, and the sum of the first two is 6 mor
mr_godi [17]
Let the second score = x
⇒ second score = x

<span>the first is 14 points more than the second
</span>⇒ first score = x + 14

<span>the sum of the first two is 6 more than twice the third
</span>⇒ third score = 1/2 (x + x + 14 - 6) = x + 4

<span>The sum of a student's three score is 246
</span>⇒ x + (x + 14) + (x + 4) = 246
<span>
Solve x:
</span>x + x + 14 + x + 4 = 246
3x + 18 = 246
3x = 228
x = 76

second score = x = 76
first score = x + 14 = 76 + 14 = 90

liraira [26]

Answer:

k = 8 + 100 (.25) - 2x

Step-by-step explanation:

Since there's a flat shipping rate, you need to first add 8.

Then you have to pay for the 100 key chains at $.25 each so you have to multiply them to get the total cost.

Next you earn 2 dollars for every key chain sold which becomes the 2x. You are then subtracting this from the amount of money you are spending to get k.

You need a 75% alcohol solution. On hand, you have a 1125 mL of a 90% alcohol mixture. How much pure water will you need to add
Alex777 [14]
\bf \begin{array}{lccclll}&#10;&amount&concentration&&#10;\begin{array}{llll}&#10;concentrated\\&#10;amount&#10;\end{array}\\&#10;&-----&-------&-------\\&#10;\textit{90\% sol'n}&1125&0.9&(1125)0.9\\&#10;\textit{water}&x&0&0x\\&#10;-----&-----&-------&-------\\&#10;mixture&y&0.75&0.75y&#10;\end{array}

so.. whatever "x" is, we know 1125 + x = y
and whatever the alcohol concentration yield may be, we know

(1125)(0.9) = 0.75y

(1125)(0.9) = 0.75y   <--- solve for "y", that's how much the final amount of milliliters will be

how much pure water was added? subtract 1125 from that, or y - 1125
