Darlene has 634 gallons of gasoline. Every time she mows her lawn, she uses 38 gallon. How many times can she mow her lawn before she needs more gas?
Answer: 16 times
Step-by-step explanation:
So in this situation, an equation helps!
634 = 38x
Where 634 is the number of gallons of gas she has; 38x is how much she needs to mow her lawn each time.
Now simply divide!
If we round we get x= 16.68 however this is not the correct answer because you can't mow 68/100 of a lawn! So even though 0.68 is greater than 0.5, we would round down to 16.
Write as a monomial in standard form.
The expression will be written in monomial standard form as -64x⁶a³.
A monomial may be defined as an expression which consists of only one term. If we are to write an expression in monomial standard form, then we will have to form an expression consisting of numbers and variable along with their powers. The variable containing the maximum power will be written first and so on. In the question we have to write monomial standard form of third power of (-4ax³). This can be written as
(-4ax³)³ and on further expanding
-64a³x⁶, but in standard from we write the variable having maximum power first, so we rearrange the terms, and we get
-64x⁶a³ which is the required answer.

2(8-2x)+2(4-2x)=18 what is x?
Answer:
x=3/4
Step-by-step explanation:
Answer: x = 3/4
Step-by-step explanation:
2(8 - 2x) + 2(4 - 2x) = 18
2(-2 x 8) + 2(4 - 2x) = 18
-4x + 16 + 2(4 - 2x) = 18
-4x + 16 + 2(2x + 4) = 18
-4x + 16 - 4x + 8 = 18
-4x + 24 - 4x = 18
-8x + 24 = 18
-8x + 24 - 24 = 18 - 24
-8x = -6
-8x/-8 = -6/-8
x = 3/4

Answer:
A. yes the y-intercept is 2
B. the graph is a straight line
C. The Slope of the Line is 1/2
D. The line Does Not pass through the origin
Step-by-step explanation:
A. the y-intercept is when x=0... y=([tex]\frac{-1}{2}[/tex]*0)+2
B. It is a straight line because x is raised to the 1st power and not another number
C. Although the slope of the equation is [tex]\frac{-1}{2}[/tex]... the slope is still 1/2
D. The line Does Not pass through the origin
origin= (0,0)
x=0 --> y=([tex]\frac{-1}{2}[/tex]*0)+2=
y=0---> 0=([tex]\frac{-1}{2}[/tex]*x)+2
[tex]\frac{-x}{2}[/tex]=2---> x=-4
Answer:
The first two statements are true.
Click "The y-intercept of the line is 2" and "The graph is a straight line"
Step-by-step explanation:
The most important thing to know for this question is the equation of a line, y=mx+c, where m is the slope of the line and c is the y-intercept (where the lines crosses the y-axis).
Our formula is y= - [tex]\frac{1}{2}[/tex]x+2, which means the y-intercept is 2. Therefore, the first statement is true.
The equation follows the general equation for a straight line, so the second statement is true.
Our formula is y= - [tex]\frac{1}{2}[/tex]x+2, which means the slope is - [tex]\frac{1}{2}[/tex], not [tex]\frac{1}{2}[/tex]. Therefore, the third statement is not true.
For a line to pass through the origin (0,0), it's y-intercept must be 0, but we already know the y-intercept here is 2. Therefore, the fourth statement is not true.
To see if the line passes through (0, -2), we must sub these values into the equation and see if it makes sense
y= - [tex]\frac{1}{2}[/tex]x+2?
-2=- [tex]\frac{1}{2}[/tex](0)+2?
-2 = 2? This is not true, so the last statement is also not true.

Simplify fully 2(m+11)/10m
On simplifying the given equation, the result would be: 1/5 + 11/5m
How to simplify expressions?The technique of writing an algebraic expression in the most effective and compact form without altering the original expression's value is known as simplification.
The procedure involves gathering related phrases, which calls for adding or removing terms from an expression.
Let's review a few key words that are utilized while simplifying an expression:
In an algebraic expression, a variable is a letter whose value is unknowable.
A numerical value used in conjunction with a variable is the coefficient.
A phrase with a known value is referred to as a constant.
Similar letter and power variables are referred to as like words. Sometimes various coefficients might be found between like terms. For instance, the phrases 6x2 and 5x2 are comparable because they both have variables with exponents of 2. Similar to this, 7yx and 5xz are dissimilar concepts because they each have unique variables.
The fundamental guidelines and procedures to simplify any algebraic statement are as follows:
-By multiplying factors, remove any grouping symbols like brackets and parenthesis.
-If the terms contain exponents, use the exponent rule to eliminate grouping.
-Add or subtract like terms to combine them.
Add the constants together.
As per the question:
2(m+11)/10m =(m+11)/5m
=1/5 + 11/5m

How to determine the integers?From the question, the statement is given as
the product of two positive consecutive integers is 132.
Represent the consecutive integers with x and y
Where y = x + 1
So, we have
the product of x and y is 132.
Mathematically, this can be represented as
x * y = 132
Substitute y = x + 1 in x * y = 132
x * (x + 1) = 132
Express 132 as 11 * 12
x * (x + 1) = 11 * 12
This means that
x =11
Substitute x =11 in y = x + 1
y = 11 + 1
Evaluate
y = 12
Hence, the integers are 11 and 12

Based on the amount invested, and the interest, the amount after 3 years would be $567.86
The interest is compounded monthly so you must convert it to a monthly rate:
= 4.25% / 12 months
= 4.25/12%
Number of periods:
= 3 years x 12 months
= 36 months
The future value of this amount is:
= Amount x ( 1 + rate) ^ number of periods

Your distance from lightning varies directly with
the time it takes you to hear thunder. If you
hear thunder 10 seconds after you see lightning,
you are about 2 miles from the lightning.
Estimate how many seconds it would take for
the thunder to travel a distance of 5 miles.?
The time taken by thunder to travel a distance of 5 miles is 25 seconds.
Which is the direct variation?A direct variation, as well known as a direct proportion, is a relationship that exists between two variables.Your distance from lightning differs directly with duration it takes you to hear thunder. If you hear thunder 10 seconds upon seeing lightning, you are approximately 2 miles away.Let d denote the distance and t the time.
Distance varies linearly with time, implying that distance is proportional to time.
Distance ∝ Time
d ∝ t
When the proportionality symbol is removed;
d = kt or k = d/t
Where k is the constant of proportionality.
In the equation, d = 2 and t = 10 are substituted.
k = 2/10 = 1/5
Therefore,
The following is a direct variation formula for the correlation between time and distance: d = (1/5)t
Now, for the distance of 5 miles, the time taken by the thunder is-
5 = (1/5)t
t = 5 × 5
t = 25 seconds.
Thus, the time taken by thunder to travel a distance of 5 miles is 25 seconds.
