The LCD PLEASEEEE
EEEEE
Answer:
-2
Step-by-step explanation:
(x + 2) ÷ 2 + (x + 4) ÷ 4 = 4
lcm is 6
(x + 2) ÷ 2 × 6 + (x + 4) ÷ 3 × 6 = 4
(x + 2) × 3 + ( x + 4) × 2 = 4
3x + 6 + 2x + 8 = 4
correct like terms
3x + 2x + 6 + 8 = 4
5x + 14 = 4
5x + 14 - 14 = 4 - 14
5x = - 10
5x ÷ 5 = -10 ÷ 5
x = -2

At the last basketball game ,12 out of the first 48 people who entered the stands were wearing a coat. if this sample is representative of the 200 people attending the game , about how many are wearing a coat?
Answer: attending the game
Step-by-step explanation:
Given: 12 out of the first 48 people who entered the stands were wearing a coat.
That means, Proportion of people wearing coat = [tex]\dfrac{12}{48}=\dfrac{1}{4}[/tex] (People wearing coat divided by Total people)
Total people in the sample attending the game= 200
Number of people wearing a coat = [tex]200\times\dfrac14[/tex]
[tex]=50[/tex]
Hence, 50 people are wearing a coat.

Answer:
26
Step-by-step explanation:
m + 5q | Given
1 + 5(5) | Substitute the values
1 + 25 | Distribute (5(5) is the same as writing 5 × 5
26
The solution of m + 5q is 26, where m = 1, and q = 5.
What is expression?Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation : Divides left hand operand by right hand operand
For example 4/2 = 2
Given expression as :
⇒ m + 5q
where m = 1, and q = 5
Substitute the values of m = 1, and q = 5 in the expression and apply the arithmetic operations
⇒ 1 + 5(5)
⇒ 1 + 25
⇒ 26
Hence, the solution of m + 5q is 26, where m = 1, and q = 5.

The ratio of teachers to students in a particular school is 1 to 11. The ratio of female students to the total number of students is 4 to 9. If there are 396 female students, then how many teachers are there?
Answer:
81
Step-by-step explanation:
Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]
[tex]\frac{4}{9}[/tex] = [tex]\frac{396}{x}[/tex] so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.
You could set up another proportion 1/11 = x/891
If there are 396 female students, there are 81 teachers.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
First, Set up a proportion to find how many total students there are
[notice how females are on top and totals are on the bottom of the ratios]
So, 4/9 = 396 / x
then, cross multiply
4x = 396(9)
so x = 891,
if there are a total of 891 students and we need 1 teacher per 11 students then take 891/11.
Thus, you need 81 teachers.
Also, we could set up another proportion 1/11 = x/891
Hence, If there are 396 female students, there are 81 teachers.

Work out the equation of the line which has a gradient of 1/2 and passed through the point (4,-2)
Answer:
2y-x = -8
Step-by-step explanation:
The equation if a line ilin point slope form is expressed as;
y-y0 = m(x-x0)
M is the slope
(X0,y0) is the point
Substitute
y - (-2) = 1/2(x-4)
y+2 = 1/2(x-4)
2(y+2) = x-4
2y+4 = x-4
2y-x = -8
Hence the required equation is 2y-x = -8

The temperature was -2°F in the afternoon and is now -30°F. How many degrees did it drop?
Answer:
28°
Step-by-step explanation:
Let's take 'x' as the number of how much degrees it dropped. So this is how the equation will look like:
-2 - x = -30
It is '-x' since the temperature 'decreased', so you must a subtract.
Take -30 to the other side and substitute it with '-x'. Since both the terms are shifted, -30 will be +30 and -x will be +x (which is equivalent to x).
x = -2 + 30
x = 28°
∴ There was a 28° drop.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.
We are given that grocery store sells a bag of 7 oranges for $4.48. If Khloe spent $6.40 on oranges, then
We have to do as $4.48 divide by 7
4.48 / 7 = $0.46
Therefore, Each orange costs $0.64
For 10 oranges;
$0.46 x 10 = $6.40
