To evaluate the following expression, what step should you do first? 7 X (4 + 16) = 4 - 2
Answer:
Remember BODMAS
Bracket first, then division, then multiplication, then addition, then substraction
Answer:
PEMDASStep-by-step explanation:
In order to evaluate the expression, use PEMDAS. It stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction.7 × (4 + 16) ÷ 4 - 2 7 × 20 ÷ 4 - 2 = ?140 ÷ 4 - 2 = ?35 - 2 = ?32[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]

Also could someone please explain how to do this??
9514 1404 393
Answer:
x = -20
Step-by-step explanation:
First, simplify the equation. Eliminate parentheses and combine terms.
3(x -1) -8 = 4(1 +x) +5 . . . . . . . given
3x -3 -8 = 4 +4x +5 . . . . . . . . eliminate parentheses (distributive property)
3x -11 = 4x +9 . . . . . . . . . . . . combine like terms
We can put all the x-terms on the right by subtracting 3x from both sides.
3x -11 -3x = 4x +9 -3x
-11 = x +9
And we can get the x-term by itself by subtracting 9 from both sides.
-11 -9 = x +9 -9
-20 = x . . . . . . . . . . this is the solution
__
Check
3(-20 -1) -8 = 4(1 -20) +5
3(-21) -8 = 4(-19) +5
-63 -8 = -76 +5
-71 = -71 . . . . . . . . . true, the answer checks OK
_____
Additional comment
We observe that the two x-terms are 3x and 4x. The smaller of these is 3x, so when we subtract that from 4x we will have a positive result. That is why we chose to subtract 3x, even though it leaves the x-term on the right side of the equation. We could have subtracted 4x to get -x -11 = 9. I find it easier not to make a mistake if the variable has a positive coefficient.
50 is times as much as
Answer:
i dont really understand this question though but ill try. Ok so 50 times, to say this you would have to take a number then multiply that number by 50 and you would get your answer. but this is the only way i think you could say 50 is times as much as.

the cost of a pen is rupees 9 2/5 and that of a pencil is rupees 3 1/5. Which costs more and by how much
Hello :D
The pen is 9 2/5 rupees and the pencil is 3 1/5 rupees. To work this out we need to subtract them from each other.
9 2/5 - 3 1/5 = 6 1/5 rupees.
The pen cost more by 6 1/5 rupees.

What is the difference between the mass of a solid and the mass of a liquid?
Answer:
A solid is a form of matter characterized by a particular shape that also has volume. A liquid, on the other hand, has volume but no exact shape, taking the shape of its container. The molecules in solid matter are compressed as its molecules are closely bound together and can only vibrate.

Class : 7
Subject: optional mathematics
okok I know its easy
Answer:
37 kg
Step-by-step explanation:
Put the numbers in order from least to greatest
30, 32, 35, 37, 40, 42, 45
cross numbers out until you get to the middle number
30, 32, 35, 37, 40, 42, 45
32, 35, 37, 40, 42
35, 37, 40
37 kg
Explanation :
We know that, the median of an ungrouped data is the number in the middle of sequence when it is arranged ascending or depending and the number of terms is odd.
therfore , the sequence will be :
30kg , 32kg , 35kg , 37kg , 40kg , 42kg , 45kg
Here, 37 kg is the middle value i.e median of the given data .

1 1/11 rewrite each number as a single fraction greater then one
Answer:
12/11
Step-by-step explanation:
11/11=1
1/11=1/11
11/11+1/11=12/11
[tex]1\frac{1}{11}[/tex] rewritten as a single fraction is 12/11
[tex]1\frac{1}{11}[/tex] is a mixed fraction.
A fraction is a number that is made up of a numerator and a denominator.
A mixed fraction is made up of a whole number and a proper fraction. A proper fraction is a fraction that is made up of a numerator that is less than a denominator.
For example, [tex]\frac{1}{11}[/tex] is a proper fraction. The numerataor,1, is less than the denominator, 11.
We are to convert the mixed fraction to an improper fraction. An improper fraction is a fraction that its numerator is greater than the denominator.
In order to convert to an improper fraction, take these steps
multiply the whole number with the denominator ( 1x 11) = 11Add the numerator to the answer gotten in the previous step = 11 + 1 = 12 Divide the answer gotten in the previous step by the denominator : 12/11A similar question was answered here: https://brainly.com/question/14549871?referrer=searchResults

The length of a rectangle is four times its width. If the perimeter of the rectangle is 50 in, find its area
Answer:
The perimeter of a rectangle is the sum of all of it’s sides. Since a rectangle has 2 lengths of the same size and two widths of the same size, the perimeter is length + length + width + width, or 2(length) + 2(width), or, to make it shorter, 2l + 2w.
Since the length of the rectangle (l) in this scenario is really 4w, we can replace those, and get 2(4w) + 2w, and since we know the total is 50, we can say 2(4w) + 2w = 50.
Using the distributive property, we get 8w + 2w = 50, and 10w = 50, or w = 5. Since the length is 4w, the length is 4*5 = 20.
To find the area, you multiply length and width to get 5 * 20 = 100 sq meters.
