Answer:
35 - m is the expression used to determine the number of gallons left in the tank after m minutes.
Step-by-step explanation:
Given:
Tank with 35 gallons of water is leaking at a rate of gallon per minuteCalculations:
Let "m" represent the number of minutes spent Number of gallons left in the tank = initial amount of water present – leaked amount of water [tex]=35-m * 1=35-m[/tex] The required expression is 35 – mIn 1940 you could buy a soda for 5 cents. Today the average cost of the same size soda is $1.25. What is the percent of increase in the cost of a soda?
Answer:
2400%
Step-by-step explanation:
Answer: 2,400%
Step-by-step explanation:
1.25 * 100/0.05 = 2,500
2,500% - 100% = 2,400%
A rectangle has a length of x inches and a width 2 inches less than the length. If the dimensions were doubled, what would be the area, in square inches , of the new rectangle in terms of x
Answer:
Option (4)
Step-by-step explanation:
Area of a rectangle = Length × width
If the dimensions of the given rectangle is doubled,
Area of the new rectangle = 2(Length) × 2(width)
= 4(Length × width)
= 4(x)(x - 2)
= 4[x² - 2x]
= 4x² - 8x
Therefore, Option (4) will be the correct option.

Answer/Step-by-step explanation:
Shari's equation, 288x - 4y = -192, was stated in the standard form.
Thus, she thinks -192 was the y-intercept because:
She thought that the [constant term] is always the y-intercept. She forgot to [write the equation in slope-intercept form].
Let's find the correct y-intercept (b), by first rewriting the equation, 288x - 4y = -192, to get the equation in slope form, y = mx + b.
Thus:
288x - 4y = -192
-4y = -288x - 192 (subtraction property of equality)
y = -288x/-4 - 192/-4
y = 72x + 48
Thus, the y-intercept = b = 48

Keyla traveled 2155 kilometers by car to visit some relatives. If 1 km is approximately 0.62 miles, then what is the number of miles Keyla traveled to the nearest unit? 1,336 miles 7,471 miles 2,877 miles 3,470 miles
Answer:
1336miles.
Step-by-step explanation:
From the question we are told that;
1km represents 0.62miles
1km = 0.62miles
We are to express 2155kilometers in miles.
2155km = x miles
Find x:
Divide both equations;
1/2155 = 0.62/x
Cross multiply;
1 * x = 2155 * 0.62
x = 1,336.1miles
Hence the correct option is 1336miles.
Michael is riding his tricycle, he has a head start of 5 meters and is pedaling at 2 meters every 3 seconds. What is the equation of the line? What is the independent and dependent variables?
Answer:
The correct answer is
y = 2 ÷ 3x + 5
where,
x = independent variable
y = dependent variable
Step-by-step explanation:
According to the given scenario, the equation of the line, independent and the dependent variable is as follows:
y = mx + b
Since the head is started with 5 meters and the pedaling at 2 meters for every 3 seconds i.e. 2 ÷ 3
So the equation line is
y = 2 ÷ 3x + 5
where,
x = independent variable
y = dependent variable

Rewrite the equation C = 2nr to show the expression that can be used to find the value of r.
The process is:
C = 2nr
2nr = c
r (2n) = c
[tex]r = \frac{c}{2n} [/tex]
That's the answer☝️☝️☝️☝️
or maybe this one
r = 2n + c
sorry, I'm unsure, it has been too long since I studied that...
Answer:
C = 2nr
you divide by 2n both sides
that means C/2n = 2nr/2n
after that you simplify then it will be C/2n = r
r = C/2n
I need help with this plz percent equations 100% of blank = 600,000
Answer:
100% of 600,000 = 600,000
Step-by-step explanation:
The answer will be 600,000
Since
100% of 6,000,000 = 6,000,000 so,
100% of 600,000 = 600,000

Answer:
y + 2x - 3 = 0
Step-by-step explanation:
You should learn the topic.
Answer:
2x+y-3=0
Step-by-step explanation:
The standard form is a representation of equations that start from the variable term towards the constant term, generally leaving the RHS empty.
Here,
[tex]y=-2x+3\\y+2x=3\\y+2x-3=0\\2x+y-3=0[/tex]
bag of sweets £1.50 per bag, buy 3 get 1 free how many sweets can you buy for £9
Answer: 8
if you're talking about how many bags of sweets you can BUY, as in without counting the ones you got for free, it's 6. if you're talking how much you GOT, it's 8.
Step-by-step explanation: you can multiply 1.5 times an unknown number to get nine. the unknown number would be the number of bag of sweets you get without the "buy 3 get 1 free" thing. You can reverse the equation to get 9 divided by 1.5 equals 6.
you can then divide 6 by three, which is 2- meaning you got two free bags of sweets. 6 plus 2 is 8.
Answer:
8 I believe
Step-by-step explanation:
1.50 x 3 = 4.50 so for 4 bags you need 4.50
1.50 x 6 = 9 but you can't forget about the buy 3 get 1 deal
you bought 6 which is two times 3 so would get two free
6+2= 8

[tex]2w - \frac{ 7}{4} [/tex]
Step-by-step explanation:
[tex] \frac{1}{4} \times 8w = 2w \\ \frac{1}{4} \times ( - 7) = \frac{ - 7}{4} [/tex]
Answer: 2w -7/4
Step-by-step explanation:
1 /4(8w − 7)
Apply the distributive property.
1 /4(8w − 7) + 1/4 ⋅ − 7
Cancel the common factor of 4.
Factor 4 out of 8w.
2w + 1/4 ⋅ -7
Combine 1/4 and -7
2w + ((-7)/4)
Move the negative in front of the fraction.
2w − 7/4

A 45-foot water slide casts a 30-foot shadow.
Find the length of the shadow of a 4-foot tall child
standing nearby.
Answer:
2.666666666666666666666666 ( repeating decimal )
Step-by-step explanation:
It says a 45 foot slide casts a 30 foot shadow.
We notice that 30 is exactly 2 / 3 of 45.
A easier way to notice that is like 30 + (half of 30 which is 15)
so 30 + 15 is 45 which is exactly the height of the water slide.
The we take the 4 foot child. It is 4 foot.
Then we do 4 times 2 / 3 which we got earlier.
which will be 2.66666666666666666666666666666666666
repeating decimal don't know how to write it here
