20y + 36
I don't know.
Answer:
20y + 36
Step-by-step explanation:
Distribute the 4 to everything in the parenthesis (multiply).
4 x 5y = 20y
4 x 9 = 36
The solution of the expression 4(5y + 9 ) will be 20y + 36. The correct option is C.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The expression 4(5y+9) will be solved as below:-
E = 4 ( 5y+9 )
E = 20 y + 36
Therefore, the solution of the expression 4(5y + 9 ) will be 20y + 36. The correct option is C.

Find the lest number which is exactly divisible by 36 & 90 Maths
Answer:
180Step-by-step explanation:
You need to find the HCF of 36 and 90.
Prime factors of each:
36 = 2*2*3*390 = 2*3*3*5HCF includes all prime factors of both numbers:
HCF(36, 90) = 2*2*3*3*5 = 180To find the least number,
Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.
→ 36 = 2 × 2 × 3 × 3
→ 90 = 2 × 3 × 3 × 5
Then the required HCF will be,
→ 2 × 2 × 3 × 3 × 5
→ 180 (HCF)
Thus, 180 is the least number which is exactly divisible by 36 and 90.

Answer:
Step-by-step explanation:
24,000 = 24 thousands
30,000 = 30 thousands
3,000 = 3 thousands
2,4000 = 2.4 thousands
"x" years
24 + 3x = 30 + 2.4x

and solve an equation which can be used to determine x, the number of miles in the
taxi ride.
Answer:
if you do 39.80/3 it would give you 13.2667 miles and since the tip was not added thats when you dont do anything with that number and 3 because every mile you pay 3$

3. Diya's chances of winning the game are
only 40%.
Express this as a probability fraction.
Answer:
2/5
Step-by-step explanation:
40% as a fraction is 4/10, when this fraction is simplified, it ends up as 2/5.
The probability of the event that Diya's chance of wining the game is 0.4 or 2/5.
What is probability of an event?The probability of an event is the chance of happening that particular event.
Let, Diya can play a game 100 times.
Therefore, the number of times she can win the game is 40.
Let, D = the event that Diya is participating in the game.
Therefore, the probability that Diya will win the game is

We have two options for x; it is either 6 or greater than 6:
If [tex]x=6\\[/tex], [tex]\mid x-6 \mid = \mid 6-6 \mid = \mid 0 \mid = 0\\[/tex].
If [tex]x > 6[/tex], [tex]\mid x-6 \mid > \mid 6-6 \mid[/tex] => [tex]\mid x-6 \mid > 0[/tex].
(for example, if [tex]x=7\\[/tex], [tex]\mid x-6 \mid = \mid 7-6 \mid = \mid 1 \mid = 1 > 0[/tex])

Ezekiel decomposed the rectangle shown into three smaller rectangles. Then he demonstrated the Distributive Property by modeling the area of the entire rectangle in terms of the three smaller rectangles. Which equation could Ezekiel have used?
answer choices:
1. 21(3 + 3) = 21(3) + 21(3)
2. 6(6 + 12 + 3) = 6(6) + 6(12) + 6(3)
3. 21(3 + 2 + 3) = 21(3) + 21(2) + 21(3)
4. 6(10 + 10 + 11) = 6(10) + 6(10) + 6(11)
Answer:
2. 6(6+12+3) = 6(6)+6(12) + 6(3) = 36+72 + 18 = 126 unit square
Area = 126 unit square.
and satisfies the 3 rectangle area. However can such amounts fit inside the rectangle as distributable?
We prove length of 21 units =
21-6 = 15 Units length and 15 - 12 = 3. Proves all 3 measures of length does fit within the length of 21 units length
Conclusion Does satisfy as three length measures within one larger measure given for the large rectangle fit exact, to find area identical in totals.
Step-by-step explanation:
Proof area of 21 x 6 area rectangle = 126unit square
3 smaller rectangles made from same larger rectangle must = 126 unit square when all 3 smaller area are added together.
answer choices
1. 21(3+3) = 2(3)+21(3) only shows 2 rectangles area = 2 rectangles angle
Does not satisfy
2. 6(6+12+3) = 6(6)+6(12) + 6(3) = 36+72 + 18 = 126 unit square and satisfies the 3 rectangle area. However can such amounts fit inside the rectangle as distributable?
We prove length of 21 units =
21-6 = 15 Units length and 15 - 12 = 3. Proves it does fit within the width of 21 units length
Conclusion Does satisfy as three length measures within one larger measure given for the large rectangle fit exact, to find area identical in totals.
3. 21 (3+2+3) = 21 (3) +21 (2)+21 (3) does not satisfy 6 units width as 3+2+3 = 8 and is too high a number. Does not satisfy.
4.6(10+10+11) = 6(10) + 6(10) + 6(11) does not satisfy
The lengths of the three rectangles adds to 31 length as 10+10+11 = 31 instead of 21. Does not satisfy.
