Answer:

Quick answer is B

Step-by-step explanation:

Use the rise over run method Y2-Y1 over X2-X1 and get your fraction. Divide your fraction to get your number and you get 15. Your equation should be simalar to this 75-30 over 5-2= 45 over 3 which is equal to 15.

Rewrite the following statements less formally, without using variables. Determine, as best as you can, whether the statements a
Anni [7]

Answer:

The answer is given below

Step-by-step explanation:

a) Let u and v be real numbers. The sum of u and v = u + v and the difference between u and v = u - v.

u + v < u - v means the sum of two real numbers is less than the difference between the two numbers.

There exist two real numbers such that their sum is less than the difference between them

This is true when atleast one of the numbers is negative, for example u = 2 and v = -2

u + v = 2 + (-2) = 0 , u - v = 2 - (-2) = 4

u + v < u - v.

b) Let x be a real number and x² be the square of the real number

x² < x means that the square of a real number is less than the real number

We can rewrite the statement as: There exist a real number such that its square is smaller than itself.

The statement is true for x is between 0 and ±1

E.g. for x = 1/2, x² = (1/2)² = 1/4

1/4 < 1/2

c) Let n represent all positive integers. n² is the square of n.

n²≥n means that the square of n is greater or equal to n.

We can rewrite the statement as: For all positive integer numbers, the square of the number is greater than or equal to the number itself

The statement is true.

1² ≥ 1, 2² ≥ 2 e.t.c

d)  Let a and b be real numbers. The sum of a and b = a + b. |a| is the absolute value of a and |b| is the absolute value of b

|a+b|≤|a|+|b| means the absolute value of the sum of two real numbers is less than or equal to the sum of their individual absolute value.

We can rewrite the statement as: For two real numbers, the absolute value of their sum is less than or equal to their individual absolute value sum.

This statement is true for all real numbers.

Rufina [12.5K]

Answer:

Total seashells = (6g + 10) seashells.

Step-by-step explanation:

Given that Mario collected 3g seashells.

Given that Jasmine collected 10 more seashells that mario. It means she collected (3g+10) seashells.

It says to write the number of seashells they collected together in terms of g.

Total seashells = Mario's seashells + Jasmine's seashells.

Total seashells = 3g + (3g+10).

Total seashells = 6g + 10.

Hence, Total seashells = (6g + 10) seashells.

Write and solve an equation to find the value of x and the missing angle measures
Alinara [238K]

Answer:

85 degrees

Step-by-step explanation:

its really easy just make them equal to eachother and then solve

9x + 13 = 11x-3

-11x (subtract because 11x is positive)

-2x +13 = -3

-13 (subtract because 13 is positive)

-2x = -16

divide both sides by -2

x= 8

substitute 8 for the x's and you have your answer
