What is 3x+6y=16. what do i do please help

1 answer:

7 0

Ok, so for this you're likely graphing in y=mx+b format (slope intercept). So to start, you'all first subtract 3x from the equation to get 6y=-3x+16. Now you'll divide the equation by 6 to get y alone. Your final equation will be y=-1/2x+16/6

A chef placed an order for 50 pounds of fish. He calculated that he will need 20 3/5 pounds for lunch orders. How much fish will

andrezito [222]

Answer:

29 2/5

Step-by-step explanation:

We know that 5 fifths make up a whole. The chef only needs 3/5 of that whole, so we still have 2 fifths remaining. Now, we have to subtract 50 by the number of lunch orders, 20. 50 subtracted by 20 is equal to 30, but we have to subtract a whole because of the fraction. We get the number 29. Then, we add the remaining fraction back. We get the answer as 29 2/5.

Best of Luck!

3. Find the difference between the two expressions.<br> (3/5x - 5y) - (4/5x + 2y

andriy [413]

Answer:

$^{-1}/_{5}x-7y$

Step-by-step explanation:

Our equation is

$(^{3}/_{5}-5y)-(^{4}/_{5}+2y)$

now we distribute the - and we get

$^{3}/_{5}-5y-^{4}/_{5}-2y$

$Combine$ $like$ $terms$

and now we have $^{-1}/_{5}x-7y$

Y=6-x In this case, what would be the slope and y-intercept? I'm having a hard time trying to get it to the y=mx+b format.

frutty [35]

Answer:

Slope = $\frac{-1}{1}$ or -1

y = 6

Step-by-step explanation:

The equation given (y = 6 - x) is the same as saying

y = -1x + 6

Since we have a negative x variable and a positive 6 and would also be graphed the same. The only difference is that the second equation I just mentioned resembles the y = mx + b expression more. In this case the slope would be

Slope = $\frac{-1}{1}$ or -1

While the y-intercept would be

y = 6 - x

y = 6 - 0

y = 6

Quiana has 7 times more text messages from Yolanda than from Pierre. Quiana has 56 text messages from Yolanda. Which equation ca

gizmo_the_mogwai [7]

Answer:

Quiana has 8 text messages from Pierre.

Step-by-step explanation:

This question can be solved using a rule of three.

Quiana has 7 times more text messages from Yolanda than from Pierre.

This means that for each message that she receives from Pierre, she receives 7 from Yolanda.

She received 56 from Yolanda.

7 messages from Yolanda - 1 messages from Pierre

56 messages from Yolanda - x messages from Pierre

$7x = 56$

$x = \frac{56}{7}$

$x = 8$

Quiana has 8 text messages from Pierre.
