The value of the inequality is x ≤ 20/3
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
3x + 10 ≤ 30 be equation (1)
On simplifying , we get
Subtracting 10 on both sides , we get
3x ≤ ( 30 - 10 )
3x ≤ 20
Divide by 3 on both sides , we get
x ≤ 20/3
x ≤ 6.333
Therefore , the value of x is less than or equal to ( 20/3 )
Hence , the inequality is x ≤ 20/3

Answer:
TUJ = 29
Step-by-step explanation:
178-149
Answer:
m∠ TUJ = 29°
Step-by-step explanation:
Although this question looks hard, it really is not.
Since we know that TUV = 178° and we know that JUV = 149° we can easily figure out TUJ.
First, since we know that the total is 178° (TUV) we can subtract angle JUV from TUV to get TUJ
178° - 149° = ?
178° - 149° = 29°

Question
Set up and solve a system of equations to solve the problem.
A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of
the coins is $1.30. How many nickels and how many dimes are in the jar?
The jar contains
nickels and
dimes.
9514 1404 393
Answer:
14 nickels6 dimesStep-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.

Find the value of x.
Answer:

Step-by-step explanation:
4. Which of these points does not lie on the graph of y=-2x+7?
(A) (-1,9
(B) (4,-1)
(C) (-3,1)
(D) (-2.11)
The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.
How to plot a graph?
A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given that a line y=-2x+7
Now in order to satisfy any point of this function then the value or
coordinate should satisfy the function or line.
So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.
So all options except (C) are satisfying.
Option (C) ⇒
-2(-3) + 7 ≠ 1
Hence "The point (-3,1) is not passing through the graph y = -2x + 7".

Answer:
Step-by-step explanation:
A geometric sequence has a common ratio from term to term. Any term divided by the previous term will be a constant, common ratio.
5.1/1.7=3, 15.3/5.1=3, etc So the common ratio is 3 and thus it is a geometric sequence.

If 420 = 120%, what would 100% equal?
Answer:
350
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
120% = 120/100 = 120 ÷ 100 = 1.2
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 120% of what number = 420?
120% × ? = 420
? =
420 ÷ 120% =
420 ÷ (120 ÷ 100) =
(100 × 420) ÷ 120 =
42,000 ÷ 120 =
350
ProofHow do we check the result?If 120% × 350 = 420 =>
Divide 420 by 350...
... And see if we get as a result: 120%
Note:Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.
