Which of these is a correct identity?
x + 4x = 5x
6x = 18
2x + 1 = 7
7x + 9 = x
Answer:
x + 4x = 5x
Step-by-step explanation:
An identity is a mathematical equation that is always true (here - for all possible x's).
a). x + 4x = 5x; this is true, because for any possible x
x+4x = (1 + 4)x = 5x; there's not much to add.
b). 6x=18; evaluates to
x = 3; so it only works for one x, not all possible xs.
c). 2x + 1 = 7
2x = 6
x = 3; so it only forks for one x
d). 7x + 9 = x
6x + 9 = 0; we could compute the exact x it works for from here, but suffice to say this doesn't work for x = 0.
In between these given equations, x + 4x = 5x is the correct identity here.
What is an identity?"An identity is an equality relating one mathematical expression A to another mathematical expression B, such that A and B produce the same value for all values of the variables within a certain range of validity."
Given equations are:
1. x + 4x = 5x
⇒ 5x = 5x
This equation is true for all values of 'x'.
Hence, this is a correct identity.
2. 6x = 18
⇒ x = 3
This equation is true when x = 3.
3. 2x + 1 = 7
⇒ 2x = 6
⇒ x = 3
This equation is true when x = 3.
4. 7x + 9 = x
⇒ 6x = - 9
⇒ x = - 9/6
⇒ x = - 3/2
This equation is true when x = - 3/2.

A rafter makes an angle of 28° with the horizontal. If the rafter is 15 feet long, what is the height at the rafter's peak? Draw a diagram.
The height is 7.04 feet at the rafter's peak that makes an angle of 28° and 15 feet long.
What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Given that,
Length of rafter = 15 feet,
Angle made by rafter with the horizontal = 28°
Apply sin formula to determine the length x of the rafter,
sinθ = x / 15
sin28° = x / 15
0.469 = x / 15
x = 7.04
The height of the rafter is 7.04.

A car costs 20% less this year than last year. Last year, the car cost 5% less than the year before. The price of the car this year is $9,400. How much did the car cost 2 years ago?
Answer:
The answer is 11,374
Step-by-step explanation:
First we find 5% of 9,400 is.
9,400 * 5% = 470
Next we add 9,400 with 470 then multiply by 20%
9,400 + 470 = 9,870
9,870 * 20% = 1974
Next we add.
9,870 + 1,974 = 11,374
So, the answer is 11,374

Find the value of a in the parallelogram shown to the right note that the figure is not drawn to scale
Step-by-step explanation:
2a+26°+58°=180°
2a=180-26-58
2a=96
a=48
2*48+26=122
Given :
▪︎Measure of an angle in a parallelogram = 58°
▪︎Measure of the angle opposite this angle = (2x+26)°
We know that :
▪︎Opposite angles in a parallelogram are equal.
Which means :
[tex] =\tt 2a+ 26 = 58[/tex]
[tex] =\tt 2a = 58 - 26[/tex]
[tex] =\tt 2a= 32[/tex]
[tex] =\tt a = \frac{32}{2} [/tex]
[tex]\hookrightarrow\color{plum}\tt a = 16[/tex]
Thus, the value of a = 16
Let us now place 16 in the place of a and check whether or not we have found out the correct value of a:
[tex] =\tt 2 \times 16 + 26 = 58[/tex]
[tex] = \tt32 + 26 = 58[/tex]
[tex] =\tt 58 = 58[/tex]
Since the values in both the side match, we can conclude that we have found out the correct value of a.
▪︎Therefore, the value of a = 16

6.9+5+4.1
11+5
16
pls thanks
Answer:
16
Step-by-step explanation:
Recall that the product of a negative number and another negative number is a positive number. Thus, -(-5) = +5, and the original expression becomes
6.9 + 5 + 4.1.
Combining the mixed numbers 6.9 and 4.1, we get 11.
Combining 11 and 5 results in 16.

can yall help me 17 = x - 28?
Answer:
Step-by-step explanation:
For an algebra question like this you are trying to solve for the x.
The way you do that is to get x by itself.
So with
17 = x - 28
The step you want to do is to add 28 to both sides.
17 + 28 = x - 28 + 28
This makes makes the equation
17 + 28 = x
45 = x
Answer:
35
Step-by-step explanation:
Let's solve your equation step-by-step.
17=x−18
Step 1: Flip the equation.
x−18=17
Step 2: Add 18 to both sides.
x−18+18=17+18
