Answer:
a. 20 - (4 ⋅ 3)
Step-by-step explanation:
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Please note that multiplication 4 ⋅ 3 will happen before the subtraction -
If we add parentheses, we introduce a new "order". But if the parentheses are around the first operation we perform, the order stays the same!
This means that answer a. must be correct.
We verify:
20 − 4 ⋅ 3 = 20 - 12 = 8
a. 20 − (4 ⋅ 3) = 20 - 12 = 8
b. (20 − 4) ⋅ 3 = 16 ⋅ 3 = 48
c. 20 + 4 − 3 = 21
d. 20 ⋅ 4 − 3 = 80 - 3 = 77
Answer: A: 20 - (4 x 3)
Step-by-step explanation:
In the end, the final answer is 8, so we need to see which one of these options give us 8. As seen, we first must solve the multiplication, and the first option, A, solves the multiplication first because it is in parenthesis, which gives us 8, so the correct answer is A.

Which of the following points best represents the location of -1 5/8 on the number line?
Answer:
A
Step-by-step explanation:
Looking at the number line, you will notice that A, B, and C are less than 0.
Eliminate D, which is greater than 0.
Further still, as negative numbers get 'smaller', they go from -1 to -∞.
i.e.: -1 > -2 > -3
if you forget the above fact, looking at the number line, you can see that A is between -1 and -2, and [tex]-1\frac{5}{8}[/tex] is between -1 and -2 just as [tex]1\frac{5}{8}[/tex] is between 1 and 2.
Then, simply counting the ticks from -1 to -2, you can see that A falls on the 5th tick, while -2 falls on the 8th tick from -1.
Hope this helped.
Answer:
A

Answer: Not what's written down.
Step-by-step explanation:
Okay, so basically, if you have a letter, no other number can go with that number with a letter. So like 5x + 2b -7.
There is only one number that has x, so 5x.
Same with b. 5x + 2b.
Now, there is no letter with the 7, so that will stay the same.
So, the answer is 5x + 2b -7.
Now, I look at your question.

A bee flies 6 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 14 minutes, and then flies directly back to the hive at 4 feet per second. It is away from the hive for a total of 19 minutes. A. what equation can you use to find the distance of the flowerbed from the hive? B. How far is the flowerbed from the hive? Let d be the distance of the flowerbed from the hive.
Answer:
5 minutes
Step-by-step explanation:
d / r = t
The bee is flying for 19 - 14 minutes
(d / 6) + d / 4) = 5
Answer: 25 feet
Step-by-step explanation:
19 - 14 = 5
total travel time = 5 min
av. between 6 and 4
= 6+4÷2 = 5
5 feet per sec × 5 min = 25 feet

Determine whether the measures for the figure shown proportional.
A. the length of a side and the perimeter
B. the length of a side and the area
Answer: 5 length & width
Step-by-step explanation:
Since this is a square all sides would be the same length & width which would be 5 because each side is symmetric. So if you do 5 times as many sides as there is (5 x 4) it would give you 20
So the LENGTH of EACH side is 5 and the AREA in total or PREMIETER would be 20 all together.

*count a pair of shoes as a singular unit *
Mary oversees shoe suppliers from 3 places. she is trying to supply for
retail stores.
supplier A has 4 crates of shoes plus six loose pairs
supplier B has 6 crates of shoes, but one pair is missing
supplier C has 10 crates plus five loose pairs
assume each crate contains an equal number of shoes, write an expression describing the total number of shoes available.
write another expression describing the number of shoes available for each retail store if the shoes are divided equally among stores.
Answer: 20c + 10.
Step-by-step explanation:
(c represents crates)
I wrote each equation separately first.
Supplier A: 4c + 6
Supplier B: 6c - 1
Supplier C: 10c + 5
We can add all the cs from each supplier giving us 4c + 6c + 10c which equals 20c. Now we can add the extra shoes as, 6 + (-1) + 5 equaling 10. I wrote -1 because we are missing that shoe, but you can write it as 6 - 1 + 5 instead. Together the two numbers make the equation 20c + 10. Hope that helps : )

Martin Luther King Jr was 5 feet tall, 7 inches (67 inches) tall. The statue is 30 feet tall. What is the ratio of Martin Luther King Jr's actual height to the statue?
Answer:
67 inches : 360 inches
Step-by-step explanation:
30 feet = 360 inches
Martin Luther King Jr : Statue
67 : 360
The ratio of Martin Luther King Jr's actual height to the statue is 67 : 360.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
Martin Luther King Jr height = 5 feet tall and 7 inches
This is 67 inches tall.
The statue height = 30 feet tall.
This is 12 x 30 = 360 inches
Now,
The ratio of Martin Luther King Jr's actual height to the statue.
= 67 : 360
Thus,
The ratio is 67 : 360.

Holland added three decimals that made a sum of 2. One of the decimals was 0.34.
What are two other decimals Holland could have used to make a sum of 2? Explain how you know.
The two other numbers could be 0.83.
First, do the equation 2 - 0.34 = 1.66.
Next, divide 1.66 ÷ 2 = 0.83.
Finally, add 0.83 + 0.83 + 0.34 = 2.
So the two other decimals Holland could do is 0.83.

Write an equation with a slope: -3/4 and y-intercept: -1/4
Answer:
y = (-3/4)x - 1/4
Step-by-step explanation:
Use the slope-intercept formula y = mx + b. Here m = -3/4 and b = -1/4, and so: y = (-3/4)x - 1/4
The equation of the line with slope -3/4 and y-intercept is -1/4 is y=-3/4x-1/4.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of the line is the ratio of the rise to the run, or rise divided by the run.
It describes the steepness of line in the coordinate plane.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Given that the slope is -3/4 and y-intercept is -1/4.
We have to find the equation of line with slope -3/4 and y-intercept is -1/4.
m=-3/4 and b = -1/4
Now plug in these values in slope intercept form y=mx+b
y=-3/4x-1/4
Hence, y=-3/4x-1/4 is the equation of the line with slope -3/4 and y-intercept is -1/4.
