Step-by-step explanation:

➱ What is an equation?

Equation is a mathematical account that involves letters that are called unknowns the most used are X and Y. And it has many degrees we will see below the second degree.

➱ How to do a normal equation resolution:

➤ To solve equations we must separate the numbers with unknowns that are in the equation for the left side of the equals.

➤ And we must pass the numbers without unknowns to the right side of the equals.

➤ When the numbers are on the wrong side of the equals, we change the sign every time we change sides.

Rules:

➢ Numbers with unknowns = left side of the equals.

➢ Numbers without unknowns = right side of the equals.

➢ Changing sides = change the signal too.

Answer:

y= -5+32

3x-5(-5+32) =22

3x-25+160=22

3x= 22+25-160

3x= 47-160

3x= -113

x= [tex]\frac{-113}{3}[/tex]

Answers

Answer:

Step-by-step explanation:

21 because x= tend + lHk

Answer:

88

Step-by-step explanation:

X° + 116° = 180°(sum of opposite angle of a quadrilateral in circle is equal 180 °)

x°=180-116

x°=64°

therefore

A=(2(64)-40)

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

Answers

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

. All clothing is being marked down 15%. Which expression represents the new retail price? A) 0.85x C 1.85x (B) 1.15x D 0.15x​

Answers

Answer:

A

Hope that helps!

Step-by-step explanation:

The expression that represents all clothing is being marked down 15%.

is A) 0.85x.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

We know fractions and percentages are related.

Assuming the cost of clothing to be 'x'.

∴ After the markdown of 15% it is,

= {(100 - 15)/100}×x.

= {85/100}×x.

= 0.85x

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?​

Answers

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

Please help i really need help online school is so hard and people keep giving me the wrong answers and i just really need help :(

Answers

Answer:

2(W - 5) ≤ -29      

Step-by-step explanation:

"Twice the difference of a number and 5 is at most -29" can be expressed symbolically as follows:

2(W - 5) ≤ -29      

Further explanations:

"the difference of a number and 5" is W - 5, and thus "Twice the difference of a number and 5" is 2(W - 5).

"x ≤ -29" states "x is at most -29."

Find the HCF of 126 and 420

Answers

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

A tree is broken at a height of 7m from the ground and its top touches the ground at distance of 24m from the base of the tree. Find the original height of the tree. pls help with steps

Answers

let the broken part of tree be x
then total height of tree=7+x
since it form a right angled triangle with base 24m and height 7m and hypotenuse be x
then by using Pythagoras theorem
(hypotenuse)^2=(base)^2+(height)^2
x^2=24^2+7^2
x^2=576+49
x^2=625
x=25
therefore height of tree =x+7=25+7=31

Olivia buys cookies and apples at the store.
• She pays a total of $24.79.
• She pays a total of $4.75 for the cookies.
• She buys 4 bags of apples that each cost the same amount.

Answers

Each bag cost $5.01. Why?

Because $24.79-4.75= $20.04
You said she bought 4 bags of apples each costing the same so now you divide $20.04 by 4 giving you $5.01


Work out the length of AC.

Answers

Answer:

AC ≈ 11.3 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin23° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{AC}{29}[/tex] ( multiply both sides by 29 )

29 × sin23° = AC , then
