Problem
3.2x-1.7x+5.5=10
Steps:
1.5x + 5.5 = 10
1.5x X 10 + 5.5 X 10 = 10 X 10
15x + 55 - 55 = 100 - 55
15x = 45
15x/15 = 45/15
x = 3
Therefore questions ones answer is x = 3
Problem
3/4x-1/4x+14=3
Steps:
3/4x - 1/4x + 14 = 3
3/4x - 1/4x + 14 - 14 = 3 - 14
3/4x - 1/4x = -11
3/4x X 4 - 1/4x X 4 = -11 X 4
2x = -44
2x/2 = -44/2
x = -22
Therefore question two's answer is x = -22
Problem
3(2x+1)+x=-39
Steps:
7x + 3 = -39
7x + 3 - 3 = -39 - 3
7x = -42
7x/7 = -42/7
x = -6
Therefore question three's answer is x = -6
Problem
m+4(2m-3)+-3
Steps:
= m + 4 (2m - 3) - 3
= m + 8m - 12 - 3
= 9m - 15
Therefore question four's answer is 9m - 15
On a road map the distance from Cily A to City BIS 4 inches. The map
scale is 1 inch 20 miles what is the actual distance in miles, between
City A and City B2
5 miles
24 miles
8 miles
80
Answer:
80 miles
Step-by-step explanation:
The map scale compares the distance between two points on the map with the corresponding distance on the ground.
That is,
[tex]\boxed{\mathfrak{map\:scale=\frac{distance\:on\:map}{distance\:on\:ground} }}[/tex]
The formula makes it pretty easy to solve!
map scale is 1 inch : 20 milesdistance on map is 4 inchesLet's say, the corresponding distance on the ground is x miles.Substituting these values in the above mentioned formula:
[tex]\implies \mathsf{\frac{1 \:inch}{20\:miles} =\frac{4\:inches}{x\:miles} }[/tex]
cross multiplying:
[tex]\implies\mathsf{x=4 \times 20}[/tex]
[tex]\implies \mathsf{x=80}[/tex]
That makes the actual distance 80 miles!
ALTER
You can also use simple unitary method here:
1 inch on the map = 20 miles on the ground
∴ 4 inches on the map = 4 × 20 miles on the ground
= 80 miles on the ground

Stephanie sold half of her comic books
and then bought twenty more. She now
has 43. With how many did she begin?
please help this is due in 10 minutes!!!!!!
Answer:
Step-by-step explanation:
you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.
so 70 + 40 + 20 + 60 + 20 + 40 i believe.
this all equals 250.
ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.

Answer:
The answer is not given in the options.
Step-by-step explanation:
2x = 13
or, 2x/2 = 13/2 (multiplying with (1/2) in both sides)
or, x = 13/2
or, x = 6.5

Write the equation of the graph in slope-intercept form (y = mx + b)
Answer:
y = -3x + 4
Step-by-step explanation:
To find the slope, use rise over run with two points. The first point (0,4) to the second point (-2,-2) is 6 units down and 2 units to the right, so you can set up a fraction to solve for the slope:
-6/2 = -3
To find the y-intercept,find the point where the x-value is 0. That point is (0,4),so the y-intercept is 4.
mx represents the slope, so mx is -3x and b is the y-intercept, so that value is 4.
Answer:
y = -3x + 4
Step-by-step explanation:
m = the slope (rise/run)
b = y-intercept
we can see that the rise is 6 (based on the two points) and the run is 2 (based on the labeled points)
- that means that m = 6/2 or m = 3
y = 0 when x = 4, so the y-intercept is 4, or b = 4
put it together!
y = 3x +b
BUT WAIT!!
- the line is decreasing which means that your equation should be negative, so put a negative symbol before 3x.
- why? the rise is decreasing!
final equation --------> y = -3x + 4

Find the gradient of the line
3y + 2x = 1
how to guys
Answer:
-2/3
Step-by-step explanation:
The gradient of a line is its slope. You can just convert the equation to slope-intercept form (y=mx+b where "m" is the gradient/slope):
3y + 2x = 1
3y = 1 - 2x
y = 1/3 - 2/3x
y = -2/3x + 1/3
So, as we can see, -2/3 is the gradient/slope of the line.

How many electrons in an atom can share the quantum numbers n = 2, l = 1, ml = −1?
1
2
3
6
It's not B
Answer:
Answer is: two electrons.
n - principal quantum number, indicating relative overall energy of each orbital, n=1,2,3,...
l - angular momentum quantum number, shape of the orbital, l = 0,1,...,n−1.
l =1 for the p orbitals.
ml - magnetic quantum number, ml = 0,±1,...,±l.
This is 2px orbital, in every orbital there is two electrons with different spin.

[tex]49x - 7[/tex]
Factor out 7 from the expression and remaining will be[tex]7(7x - 1)[/tex]
Hence,Option C is correct..The solution is: Option C is correct. Factor using the GCF: 49x - 7 is
7(7x-1).
Here, we have,
given that,
we have to factor using the GCF: 49x - 7.
we know that,
In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted {\displaystyle \gcd}.
so, we have,
49x - 7
now, we know,
7 * 7 = 49
and, 7 * 1 = 7
so, we get, the GCF of 49 and 7 is 7.
so, we have,
Factor out 7 from the expression and remaining will be.
7(7x-1)
i.e. 49x - 7 = 7(7x-1)
Hence, Option C is correct. Factor using the GCF: 49x - 7 is 7(7x-1).

How to find the rational zeros of a function
Answer:
Step-by-step explanation:
Find the zeroes of the function f ( x ) = x 2 + 12 x + 32
First, because it's a polynomial, factor it f ( x ) = ( x + 8 ) ( x + 4 )
Then, set it equal to zero 0 = ( x + 8 ) ( x + 4 )
Set each factor equal to zero and the answer is x = − 8 and x = − 4 .
