Answer:
Slope-intercept is y=-x/3
The slope is -1/3
The y-intercept is 0
Step-by-step explanation:
First, we need to put this as slope-intercept for which is y=mx+b
3y=-x
y=-x/3
hope this helps!
Answer:
The slope-intercept form is y= -(1/3)x
The slope is - (1/3)
The y − intercept is 0
,
Step-by-step explanation:
x+3y=0
Substract x on both sides
3y= - x
Divide by 3 on both sides
y= - (x/3)x
y= -(1/3)x
1. Erik buys carrots and dip for a class snack. The carrots are $3.80, and the dip is $2.60. Erik has a coupon for 5% off his groceries. He does not need to pay tax. He gives the cashier $20. How much change does he receive back?
2. Liam buys a new TV that cost $360. The TV is on sale for 40% off, and the store is offering an additional 20% off all sale items. How much does Liam save on the TV?
Answer:
1. $3.80 + 2.60=$6.40 *.05=$5.08
$20.00-$5.08=$14.92
2. $360 x %40=$14,000
$14,000/100=144 360-144 = 216
$216 x %20 = $4,320/$100= $43.20
$216-43.20= $172.8
$360-$172.80=$187.20

Mei has 60 milliliters of a solution that is 35% nitric acid. How many milliliters of nitric acid does the solution contain?
(answer this and show your work please)
The solution contains _answer here_ milliliters of nitric acid.
Answer:
21ml
Step-by-step explanation:
60ml. 35% acid. What is 35% of 60 ml?
÷10 to find 10%
60÷10=6
6=10%
But this is no use
because you cannot multiply 10%to get 35%
(35% is not a multiple of 10)
So we try...
10%÷2=5%
So ÷2 to find 5%
6÷2=3
So 3=5%
5%x7=35%
So, we do
3x7=21
So 35%=21
Answer:
21ml

A cell phone costs $120. The price is reduced 30% for a sale. How much is the savings?
Answer:
the phone is 84 dollalrs
Step-by-step explanation:
Answer:
$36
Step-by-step explanation:
Since 30% = 30/100 then we can transform it into a decimal:
30%=0.30
Now if we multiply 120•0.30, we will get how much we saved.
$36, we saved $36.
Bonus information:
If the problem was to say "How much does the cell phone cost after the discount?", then you would multiply 120•0.70.
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

The diameter of the Sun is about 1.4 × 10^6 km. The diameter of Mars is about 7000 km.
What is the approximate ratio of the diameter of the Sun to the diameter of Mars?
A. 5 × 10^-3
B. 5 × 10^2
C. 2 × 10^3
D. 2 × 10^2
Answer:
C.) 2×10²
Step-by-step explanation:
(Sun dia) / (Mars dia) = (1.4 x 10⁶ km) / (0.7 × 10⁴ km) = (1.4/0.7) × 10²
The ratio of diameters is about 2 × 10².
_____
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
__
The diameter of Mars can be expressed several ways.
7000 = 7×1000 = 0.7×10,000 = 0.7×10⁴
The local newspaper has letters to the editor from 60,000 people. If this number represents 25% of all of the newspaper's readers, how many readers does the newspaper have?
(answer this and show your work thank you)
The newspaper has _answer here_ readers.
(Type an integer or a decimal.)
Answer:
The newspaper has 240,000 readers.
Step-by-step explanation:
If 60,000 is 25% of the readers.
25% = 1/4
So:
60,000/? = 1/4
60,000 x 4 = 240,000
240,000 = total ammount of readers. (Hope this helps!:))
