Answer:
Multiplicative Identity
Step-by-step explanation:
This is what they all basically mean:
Additive Identity - addition
Associative Property - simplifying
Distributive Property - multiplying brackets, or expanding
Multiplicative Identity - multiplication
In this equation, you first expand 16(4x-1) which uses multiplication but only has one bracket meaning, you use multiplicative identity first.

Solve the equation X-6+2=6 for the variable. Show each step of your solution process. (10 points)
Answer with step-by-step explanation:
x = 10
Step 1: Simplify both sides of the equation.
x - 6 + 2 = 6
x + (-6) + 2 = 6
(x) + (-6 + 2) = 6
x + (-4) = 6
x - 4 = 6
Step 2: Add 4 to both sides.
x - 4 + 4 = 6 + 4
x = 10
Hope this helped! (brainliest please)

If a - b=7, what is also true?
A
B
C
D
Answer: B. a + (-b) = 7
Step-by-step explanation:
The answer is B. a + (-b) = 7. a + (-b) is the same thing with a - b.
A. a + b = -7
a - b = 7 means the differences of a and b is 7, choice A is talking about their sum, so it could not be true.
C. -a - b = 7
if you multiply -1 on both sides, you will get a + b = -7. Therefore, it will not be true.
D. b - a = 7
a - b = 7 means that a is 7 more than b. The choice d shows the opposite, which it states that b is 7 more than a. Therefore, it is not true.
One lane on a motorway is closed by cones for a distance of 1 mile. The cones are placed 4 feet apart. How many cones are used?
Answer:
1320 cones
Step-by-step explanation:
1 mile = 5280 feet
For every 4 feet, 1 cone is placed so
5280/4 = 1320
Therefore 1320 cones are used.

A student buys two hot dogs and three drinks at the carnival for $5.25. The drinks
cost half as much as the hot dogs.
How much is each hot dog?
A $0.43
B $0.75
C $1.05
D $1.50
Answer:
B $0.75
Step-by-step explanation:
0.75x 3= 2.25
if the hotdogs are 2x as much as the drinks then
0.75x2= 1.50
then if there are 2 hot dogs
1.50x2=3
2.25+3=5.25
Andrea rolls a six-sided die. What is the probability that she rolls a number greater than 2? Give your answer as a reduced fraction or a whole number. Pease hurry
Answer:
I believe the answer would be 2/3
Step-by-step explanation:
Because if it's a 6 sided dice, and you need a number greater than 2 then there are 4 other numbers. This gives you 4/6. Simplify it and it gives you 2/3./ Hope this helps! :)

The ordered pair (-1, 4) is a solution to which of the pairs of equations? (1)
(1) y = -x + 3, y = x + 1
(2) x - y = 2, x + y = - 6
(3) x + y = - 2, 7x - 4y = 8
(4) y = -x + 3, y = 2x + 6
Answer:
d
Step-by-step explanation:
Substitute x = -1 into the equations. If the solution is y = 4 for both, then (-1, 4) is the solution.
(a) y = 1 + 3 = 4
y = -1 + 1 = 0
(b) -1 - y = 2 ⇒ y = -3
-1 + y = -6 ⇒ y = -5
(c) -1 + y = -2 ⇒ y = -1
7(-1) - 4y = 8 ⇒ y = -15/4
(d) y = 1 + 3 = 4
y = 2(-1) = 6 = 4
the sum of 8 and -13.

-104 is the answer .....

The circumference is about ft.
(Type an integer or decimal rounded to the nearest hundredth as needed.)
Review progress
Question 2
of 8
Back

Answer:
47.1 ft
Step-by-step explanation:
To find the circumference of a circle, use the formula c = πd
We know that π = 3.14 and d = 15 ft so we can substitute this into the formula:
c = 3.14 × 15 = 47.1 ft

find the median of the following 3,6,7,4,5,9,8,9,7
Answer:
7
Step-by-step explanation:
Median is the middle number from least to greatest meaning that 7 is the median.
Answer:
7
Step-by-step explanation:
Let's first sort it form lowest to highest. So it's going to be 3,4,5,6,7,7,8,9,9. Now, we ifnd the middle ofit, which is 7. The middle number of the sequence is 7 becaue there are 9 numbers total so that means that the 5th number is the median.
Find the ratio of the areas of two circles of radii 8 cm and 12 cm comparing the smaller circle to the larger circle. Write the correct answer in the space below. Don't forget to simplify your ratio (both areas have pi in them). Please write your ratio as a fraction.
Answer:
4π : 9π
Step-by-step explanation:
→ Find the area of circle with radius 8
π × 8² = 64π
→ Find the area of circle with radius 12
π × 12² = 144π
→ Simplify ratios
64π : 144π ⇒ 4π : 9π
