Acandle maker sells small candles for 10$ and large candle for 20$.on a certain day he sells 20candle overall . and makes 300 $

MAVERICK [17]

Answer:

Candle maker sold 10 Small Candles.

Step-by-step explanation:

Given:

A candle maker sells small candles for $10\$$ and large candle for $20\$$

Let the number of Small candles be $x$

Let the number of Large candles be $y$

Total candles sold is 20.

∴ $x+y=20 \ \ \ \ equation \ 1$

He makes overall $300 \$$

$10x+20y=300\\10(x+2y)=300\\x+2y=\frac{300}{10}=30\\x+2y=30 \ \ \ \ equation \ 2$

Subtracting equation 1 by equation 2 we get,

$(x+2y=30)-(x+y=20)\\y=10$

Substituting value of y in equation 1 we get,

$x+y=20\\x+10=20\\x=20-10\\x=10$

Candle Maker sold 10 Small candles and 10 Large candles.

The answer is 25. You would divided 355 by 14 and you would get 25.3571428571 and you would round it to 25 because it is impossible to have 25.3571428571 crates

Answer:

Simplifying by collecting like terms

Step-by-step explanation:

Given

See attachment for complete question

Required

The missing step

The missing step is at step 2.

At step 1, we have:

$\frac{1}{2} - 2x +1 = -\frac{13}{2}$

At step 2, we have:

$\frac{3}{2} - 2x= -\frac{13}{2}$

What she did at step 2, is that:

She collected like terms; 1 and $\frac{1}{2}$

Then she simplified the like terms: $1 + \frac{1}{2} =\frac{3}{2}$

Hence (a) is correct

I need help I'm dumb

Akimi4 [234]

Answer:

this is easy just place the value of x in the formula

Step-by-step explanation:

1) y=-2x-5 this wpuld equal y=-2(-6)-5

i am going to do one and you do the rest

y= -2(-6)-5

y= (12)-5

y= -60

Now i got 12 positive because is we look at the rule os signs -+-=+

so -2(-6)= 12

and the pharentesis= multiplication
