The algebraic equation "0.40x = 400" represents the words: forty percent of Mrs. Garcia's score is 400 points. Mrs. Garcia's score is 1000.
Algebraic equation is an equation made up of variables and coefficients that can be used to solve mathematical problems or questions.
To formulate an algebraic equation, we designate a variable for unknown values.
Mrs. Garcia's score is unknown, and so
let x = Mrs. Garcia's score
Based on the information given on the problem, forty percent of Mrs. Garcia's score is 400 points. Forty percent can be written as 0.40.
40% of x is 400
0.40x = 400
Hence, the algebraic equation for that is 0.40x = 400.
Evaluating the value of x,
0.40x = 400
x = 400 / 0.40
x = 1000
Therefore, Mrs. Garcia's score is 1000.

Mr. R's kindergarten class has 22 students. There are 2 more girls than boys in his class. How many boys are there?
let x=
let y=
Answer:
13
Step-by-step explanation:
If we want to find out if there are an equal amount of boys and girls, then we do 22/2 which is 11. BUT, it says there are two more girls than boys. So...
11+2 since there are two more boys than girls. 11+2=13 girls.

buy drinks at the refreshment stand and then walk 8 rows north and 2 rows
east to the science fiction booth. Then you walk 1 row south and 2 rows west
to the children's book booth. Where is the children's book booth in relation to
the refreshment stand?
Answer:
7 rows north of refreshment stand
Step-by-step explanation:
8 rows north and then 2 rows east followed by 1 row south and then 2 rows west will put you directly north of the refreshment stand but since you have traveled one row south, it will be 8-1 = 7 rows north of the refreshment stand

Find the HCF and LCM of 160 and 252 by prime factorisation method and verify that HCF x LCM = Product of the two given numbers.
Answer:
HCF=4
LCM=10080
HCF x LCM = Product of the two given numbers is verified because 403200=40320
Step-by-step explanation:
HCF of 160 and 252
HCF is the product of common prime factors
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
HCF= 2x2
HCF=4
40 and 63 doesn't come in any other table together so,
HCF= 2 x 2 = 4
Now, finding LCM of 160 and 252
LCM is the product of all factors of both numbers, while if any factor is common, it is considered once.
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
In the given factors 2x2 is common so, it is considered once.
LCM= 2x2x2x2x2x3x5x7
LCM= 10080
Now, checking:
HCF x LCM = Product of the two given numbers.
4x10080=160x252
403200=40320
So, It is verified that HCF x LCM = Product of the two given numbers.

I I 2x+1 I +2 I >1, step by step solution (I I is absolute value)
The absolute value of x in the inequality I 2x+1 I +2 I >1 showing the step by step solution is x > 2
What is absolute value?The absolute value of a real number x can be defined as the non-negative value of x without regard or consideration to its sign.
It is also known as the modulus of a number.
It is sometimes described as the magnitude of a real number regardless of its sign.
It is important to note that the absolute value must take a positive sign
Given the expression;
I I 2x+1 I +2 I > 1
expand the modulus value
2x + 1 + 2 > 1
collect like terms
2x > 1 + 1 + 2
Add like terms
2x > 4
Make 'x' the subject
x > 4/ 2
x > 2
Thus, the absolute value of x is x > 2

==========================================================
Work Shown:
The given values are
sin(u) = -12/13cos(v) = -8/17Through the Pythagorean trig identity, we can find
cos(u) = -5/13sin(v) = -15/17I'm skipping these steps, but let me know if you need me to go over them.
Since u and v are in quadrant 3, this means both sine and cosine are negative here
Using those four items, we can then say the following:
cos(v-u) = cos(v)cos(u) + sin(v)sin(u)
cos(v-u) = (-8/17)*(-5/13) + (-15/17)*(-12/13)
cos(v-u) = 40/221 + 180/221
cos(v-u) = (40 + 180)/221
cos(v-u) = 220/221
This is reduced as much as possible because the GCF of n and n+1 is always 1.

ethan claims that [7-3]=4. which statement about ethan claims is true
Answer:
no its not
Step-by-step explanation:
7 - 3 = ? not 4 so sub it
Answer:
Ethan's entire statement is true because he is saying that 7-3=4 and that is correct. If you have seven of something and take away 3 of them then you have 3 left.
Step-by-step explanation:
Take 7 apples for example, if you take away 3 of the apples and then count the left over you will notice that you end up with 4. Also, In a subtraction problem the larger number goes first followed by the smaller number, so that the end result is not a negative number. Hope this helps you.
