Answer:
-2/6
Step-by-step explanation:
-5n+4n-7=8
What is the answer for n and how do you solve it
Answer:
-15
Step-by-step explanation:
First combine like terms, aka the variables
-5n+4n-7=8
-1n-7=8
Then, isolate the variable by adding 7 to both sides
-1n-7+7=8+7
-1n=15
Finally, solve by dividing both sides by -1
-1n/-1=15/-1
n=-15
Answer:
n = -15
Step-by-step explanation:
I'll try my best to explain how I solved this
Equation:
-5n + 4n -7=8
Add the light terms on each side:
-n -7 =8
Separate the variables from the numbers:
-n = 15
Do the operation necessary to solve it:
n = -15

lin makes sparkling orange juice by mixing 3 liters of orange juice with 4 liters of soda water. Noah makes sparkling orange juice by mixing 4 liters of orange juice with 5 liters of soda water. How do the two mixtures compare in taste explain your reasoning
Answer:
Step-by-step explanation:
Lin makes sparkling OJ using the ratio
3:4. Meaning 3L orange juice for every 4L sparkling water.
Noah makes sparkling OJ using the ratio 4:5. Meaning 4L orange juice for 5L sparkling water.
If we said that they both used 12L of orange juice,
Lin would have to use 16L of sparkling water
Noah would have to use 15L of sparkling water
So for the same 12L of orange juice, Lin uses more sparkling water.
Therefore her sparkling OJ would be more diluted (less orange flavour since you added more water) and more bubbly than Noah's.

Find the y intercept
x-3y = 12
Help plz
Answer:
15
Step-by-step explanation:
Because 15 -3 will give you 12
Answer:
the y intercept is -4 or (0,4)
Step-by-step explanation:
To find the y intercept you have to make x zero, and vice versa. So:
0-3y = 12
-3y = 12
y = 12/-3
y = -4
the y intercept is -4 or (0,4)

A convenience store requires that Ayumi spend $4 or more if she wants to pay using a debit card. Donuts cost $0.80 each. A
bottle of orange Juice costs $1.20. Ayumi payed for 1 orange juice and d number of donuts. Write the equation that represent
the situation.
Answer
1.20+0.80d ≥ 4.00 is the equation. If you are trying to solve for the minimum of donuts she needs to buy so it is over $4.00, then it is 4
Step-by-step explanation:
So in the problem we know she already has bought one bottle of orange juice and needs to buy a certain amount of donuts but we know they are each 0.80 so that will become 0.80d. The 1.20 + 0.80d have to be greater than or equal to 4.00 so she can pay with the debit card and that is why we put the ≥ symbol.
Answer:
.80 × 4 =$3.20
orange juice is $1.20
d =.80×4 +1.20
d=$4.40

Hi can somebody help me with this equation, please? 50=2(x+3)+10
Answer: x = 17
Step-by-step explanation:
1) Subtract 10 from both sides
40 = 2(x+3)
2) Divide both sides by 2.
20 = x + 3
3) Subtract 3 from both sides
17 = x
x = 17
Answer: x= 17
Step-by-step explanation:
17 plus 3= 20
then you multiply 20 times 2 (PEMDAS)
Then you get 40 and 40 + 10
equals 50
