Answer:
x=−9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x+1)−2x=−6
(3)(x)+(3)(1)+−2x=−6(Distribute)
3x+3+−2x=−6
(3x+−2x)+(3)=−6(Combine Like Terms)
x+3=−6
x+3=−6
Step 2: Subtract 3 from both sides.
x+3−3=−6−3
x=−9

The weight of 25 folding chairs is 15 kg. How many
chairs can be loaded on a truck having a capacity of
carrying 2025 kg load?
Answer:
3,375 chairs
Step-by-step explanation:
The weight of 25 folding chairs is 15 kg
Number of folding chairs : weight
= 25 : 15
How many chairs can be loaded on a truck having a capacity of
carrying 2025 kg load?
Let number of folding chairs = x
Number of folding chairs : weight = x : 2025
Equate both ratios
25 : 15 = x : 2025
25/15 = x/2025
Cross product
25 * 2025 = 15 * x
50,625 = 15x
x = 50,625/15
x = 3,375
Number of folding chairs = 3,375 chairs
Determine how far the vehicle travels in 3 hours.
A helicopter travels 240 miles every 2 hours.
Answer:
360 miles
Step-by-step explanation:
The unit rate here is (240 miles) / (2 hours), or 120 mph.
In 3 hours the vehicle travels (120 mph)(3 hrs) = 360 miles
Answer:
360
Step-by-step explanation:
240/2 =120 So, you want to add 120 to 240 to get 360.
what is the exponent for the expression 6x6x6x6x6x6x6?
Answer:7 is the exponent
Step-by-step explanation:
Answer:
[tex]6^7[/tex]
Step-by-step explanation:
Exponents can be expressed through repeated multiplication, meaning that the amount of times one number is being repeated, would be the same amount as put in an exponent. Therefore :
6 * 6 * 6 * 6 * 6 * 6 * 6
6 is being repeated, therefore it's the constant.
6 is repeated 7 times, therefore the exponent is 7.

please help me, u have no clue what to do. all it says is find the slope of the line that passes through the given two points using ratio method.
Answer:
Triangle y = 7
Triangle x = -3
Slope = - 7/3
Step-by-step explanation:
Formula:
slope (or m) = (y2 - y1)/(x2 - x1)
Plug numbers into formula
m = 8 - 1 / 4 - 7
m = 7 / -3
Cannot be simplified further
Slope = - 7/3
The triangle before y is asking for the difference, meaning what number do you get after taking y2 (8 in this problem) and subtracting y1 (1 in this problem) from it.
8 - 1 = 7 which forms the numerator for our slope
The same goes for the triangle before x. Find the difference
x2 - x1 = 4 - 7 = -3. This forms the denominator of our slope
Find the value of x.

Twenty more than one- fifth of a number is 120. Find the number.
welp lol
Answer: x=500
Step-by-step explanation:
Twenty more (+20) of a fifth of a number (.2x) is equal to 120. So, the equation would be .2x+20=120. To isolate x, subtract 20 from each side. So now we have .2x=100. To get rid of the .2 or 1/5, we have to multiply everything by the reciprocal of 1/5, or 5. So, 100(5)=.2x(5), or simplified, x=500. Hope this helps!

A. Holli, $0.75
B. Holli, $0.50
C. Melissa, $0.75
OD. Melissa, $0.50
Answer:
C
Step-by-step explanation:
From the given table, we can calculate the earnings of Melissa.
4 hours' work makes 36 dollars
1 hour work makes=36×1/4=9 dollars
Melissa makes 9 dollars per hour.
Holli makes 8.25 dollars per hour.
So, Melissa makes more money.
9-8.25=0.75
Melissa earns 0.75 dollars more than Holli.
So, the answer is C.

For which values of x will the rational expression below be undefined? Check
all that apply.
(x - 1)(x + 1)
X + 2
A. -1
B. 1
C. -2
D. 2
E. -5
F 5
Answer:
-2
Step-by-step explanation:
For the given expression to be undefined, this means that the denominator must be zero.
From the given expression, the denominator is x + 2
Equating this to zero;
x+2 = 0
Subtract 2 from both sides
x+2-2 = 0 -2
x = -2
Hence the value of x that makes it undefined is -2

If you take a number, times by 5 then add 7. You get the same as if you took the number, times by 9 then add 3. What is the number?
Answer: The number is 1
Step-by-step explanation:
5x + 7 = 9x + 3
5x + 7 - 5x = 9x - 5x + 3
7 = 4x + 3
7 - 3 = 4x + 3 - 3
4 = 4x
x = 1

Actually Welcome to the Concept of the linear equation in two variables.
So we have to form two equations to solve this.
Let the number of children be 'x' and number of adults be 'y'.
hence, we get as,
x+y = 630 ..... (1)
and also, to their total cost spending, we get as,
1.5x + 2.25y = 1170 ...... (2)
solving (1) and (2) we get as,
Number of children were = 330
and Number of Adults were = 300

Find the HCF of 126 and 420
Answer:
42
Step-by-step explanation:
Find the prime factorization of 126
126 = 2 × 3 × 3 × 7
Find the prime factorization of 420
420 = 2 × 2 × 3 × 5 × 7
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 3 × 7
GCF = 42
The highest common factor HCF of 126 and 420 is 42
What is HCF and LCM?The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF
Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers
Product of HCF x LCM = product of two numbers
Given data ,
Let the HCF of the two numbers be represented as n
The value of n is
Let the first number be p = 126
Let the second number be q = 420
The factors of 126 = 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
The factors of 420 = 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20 , 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210 and 420
So , the highest common factor of the two numbers 126 and 420 is 42
Therefore , the value of n = 42
Hence , the HCF is 42
