7x+4-2x=6(x+1)-x
Answer:
the sides are not equalStep-by-step explanation:
7x + 4 - 2x = 6(x + 1) - x expand
7x + 4 - 2x = 6x + 6 - x combine similar terms
7x - 6x - 2x + x = 6 - 4
0 = 2 ------ no solution

Answer:
there are only two options?
Step-by-step explanation:
id say b is the answer
Answer:
B
Step-by-step explanation:
A line has a slope of 1/4 and passes through the point (0.2. 4/5).
Find the value of b, the y-intercept.
b=
Answer:
The value of the y-intercept b is 0.75
Step-by-step explanation:
Here, we want to find the value of the y-intercept
The equation of the line can be written as;
y = mx + b
where m is slope and b is the y-intercept
so y = 1/4x + c
To get the value of b , we substitute for x and y using the given point
4/5 = 1/4(0.2) + c
Multiply
0.8 = (0.25)(0.2) + b
0.8 = 0.05 + b
b = 0.8 - 0.05 = 0.75
Answer:
b=0.75

An umbrella at a shop was marked for $6 . During a sale, a discount of 10% was given. A further 8% discount was given to the senior citizens. How much would a senior citizen need to pay for the umbrella during the sale? Round your answer to the nearest cent.
Answer:
A senior citizen will pay $4.97
Step-by-step explanation:
Mathematically, discount = discount percentage * marked price
Sales price = marked price - discount
In the question, marked price = $6
First, we have a discount of 10%, so therefore , the sales price will be;
$6 - (10/100 * $6 ) = $6 - $0.6 = $5.4
Now, a further 8% discount was given to senior citizens,
The extra discount for senior citizens is thus;
8/100 * 5.4 = $0.432
Amount to be paid by senior citizens = $5.4 - $0.432 = $4.968. which is $4.97 to the nearest cent
Answer:
the answer is $4.97.

Julissa is running a 10-kilometer race at a constant pace. After running for 18 minutes, she completes 2 kilometers. After running for 54 minutes, she completes 6 kilometers. Her trainer writes an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable.
Which equation can be used to represent k, the number of kilometers Julissa runs in t minutes?
k – 2 = k minus 2 equals StartFraction 1 Over 9 left-parenthesis t minus 18 right-parenthesis.(t – 18)
k – 18 = k minus 18 equals StartFraction 1 Over 9 left-parenthesis t minus 2 right-parenthesis.(t – 2)
k – 2 = 9(t – 18)
k – 18 = 9(t – 2)

help me plz lol
Answer:
4 [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
When adding fractions, you want to make the denominators of the fraction the same. To do this, we can multiply both the numerator and denominator of 3/4 by 3. When changing either a denominator or numerator in a fraction, you must do the same thing to the numerator as the denominator.
Now we have [tex]\frac{3\cdot3}{4\cdot3} = \frac{9}{12}[/tex]. To add 9/12 and 5/12, we keep the denominator the same, and add the numerators, getting [tex]\frac{9+5}{12} =\frac{14}{12}[/tex]. This is greater than 1, so we can take 12/12 from 14/12, and make it [tex]1 \frac{2}{12}[/tex]. If we then add 3, we get [tex]4 \frac{2}{12}[/tex], which simplifies to [tex]4 \frac{1}{6}[/tex]

EMERGENCY! Please give me the correct answer!
Answer:
The answer is yes!
Step-by-step explanation:
I'm 100% sure, put it into a calculator and it'll give you 1 as the answer.
Answer:
Yes
Step-by-step explanation:
The answer is yes because:
1) As you can see, in standard form the pattern is x * 3 = y
2) If x = 1 it would match the pattern because the next number will be 1 x 3 which is 3, and then the the third number would be 3 x 3 = 9, and then the fourth number would be 9 x 3 = 27 and so on.
Hope this helps! :D

The amount of Social Security benefits received by an individual that he or she must include in gross income:
a. May not exceed the portion contributed by the employer.
b. May be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.
c. May not exceed 50% of the Social Security benefits received.
d. Is computed in the same manner as an annuity [exclusion = (cost/expected return) × amount received].
e. None of these choices are correct.
Answer:
b. May be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.
Step-by-step explanation:
Social security measures an organization to guarantee individuals against certain risks (social risks). Social security is made up of a set of institutions whose function is to protect individuals from the consequences of various events or situations, generally referred to as social risks.
Social Security is a public service of the State, ensuring all the social risks of workers, employees, liberal professions, self-employed, and non-salaried workers. Social Security provides the benefits provided by the Social Security Code. However, the amount of Social Security benefits received by an individual that they must include in gross income may be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.

Solve for y: 6x + 2y = 12
PLEASE SHOW STEPS.
(Brainliest is going to be given once 2 people answer.)
# 12 Points
solve for y first
2y=12-6×
divide each term by 2 and simplify
y=6-3x
Answer:
y=6-3x
Step-by-step explanation:
6x+2y=12
6x+2y=12 divide all by 2
3x+y=6 subtract 3x from both sides
y=6-3x

Given problem:
What is the value of x = ?
Solution:
Angle on a straight line is 180°
Sum of angles in a triangle = 180°
Now to solve the problem, we need to find the two internal angles first;
For the first one;
let us say it is y;
163 + y = 180
y = 180 - 163 = 17°
For the second, assume it is z;
69 + z = 180
z = 180 -69 = 111°
The sum of the internal angles of the triangle;
y + z + 2x = 180
17 + 111 + 2x = 180
2x = 180 - 128
2x = 52
x = [tex]\frac{52}{2}[/tex] = 26
The value of x is 26

which statement is true and represent the correct form of scientific notation
A. 5.3 x [tex]10^{-2}[/tex] = -0.053
B. 2 x [tex]10^{4}[/tex] < 20,000
C.-74.308 < -0.74 x [tex]10^{3}[/tex]
D. 12,000,000 = 1.2 x [tex]10^{7}[/tex]
Step-by-step explanation:
let express them in the same form
5.3*1/100=0.053>-0.053 so A is false
2*10^4=2*10000=20,000 is equal to 20,000 so even B is false
-0.74*10^3=-0.74*1000=-740<-74.308 so even C is false
lets see D
1.2*10^7=12*10^6=12*1000000=12,000,000 which is equal to 12,000,000 so D is true
