infinitely many solutions
Answers
Answer:
Option C) Infinitely many solutions is correct option.
Step-by-step explanation:
We need to solve the equation [tex]5x - 7x + 6 = -2(x - 3)[/tex] and find value of x
The equation can be solved using DMAS rule.
Solving:
[tex]5x - 7x + 6 = -2(x - 3)[/tex]
Multiply -2 with terms inside the bracket
[tex]5x - 7x + 6 = -2x +6[/tex]
Now, we will combine like terms. Like terms are those terms that have same variable. In our case 5x, -7x and -2x are like terms and 6,6 are like terms.
[tex]5x - 7x +2x=-6 +6\\7x-7x=-6+6\\0=0[/tex]
Solving the equation we get 0=0 it means that the solution will have infinitely many solutions, because it will be true for every value of x.
So, Option C) Infinitely many solutions is correct option.

One number is 5 more than another. The difference between their squares is 75. What are the numbers?
Answers
Answer:
The numbers are:
-10 and -5Step-by-step explanation:
Let the first number = n
As one number is 5 more than another. So,
The another number = n + 5
Given that the difference between their squares is 75, so
n² - (n + 5)² = 75
n² - (n² + 10n + 25) = 75
n² - n² - 10n - 25 = 75
0 - 10n = 75 + 25
-10n = 100
divide boths sides by -10
-10n/-10 = 100/-10
n = -10
Thus,
The first number = n = -10
The other numebr = n + 5 = -10 + 5 = -5

If you're helping tysm my guy ily
Answers
Answer 1: 5x + 4
Answer 2: 9m + -10y
Step-by-step explanation:
To simplify 3x + 9 + 2x − 5, you have to find the like terms which are 3x and 2x, and 9 and -5. So you get 3x + 2x + 9 - 5 which gives you the result of 5x + 4. Now to simplify 7m + 2 (m − 5y), you have to distribute first, so 7m + (2) (m) + (2) (−5y) which gives you 7m + 2m + −10y. So now you just have to add. 7m + 2m = 9m and then you have -10y so basically the answer is 9m + -10y.

Matching the scenario with the correct type of problem:
a. one mean
b. one proportion
c. one proportion
d. one mean
Step-by-step explanation:
A one-proportion problem is tested using the one-sample proportion test. This estimates the proportion of a population by comparing the proportion to a target or reference value. On the other hand, a one-mean problem is tested using the one-sample t-test. This tests whether a population mean is significantly different from some hypothesized value.

What do you mean by an Equation?Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.
It displays the similarity of the connections between the phrases on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.
Given data ,
Let the number of days of frog food the zookeeper has be A
Now , the value of A is
The number of cups of frog food she has = 3 cups
The number of cups of frog food she feed every day = ( 1/4 ) cups per day
Now , the equation is
A = number of cups of frog food she has / number of cups of frog food she feed every day
On simplifying the equation , we get
The number of days of frog food the zookeeper has A = 3 / ( 1/4 )
The number of days of frog food the zookeeper has A = 3 x 4
The number of days of frog food the zookeeper has A = 12 days
Hence , the number of days is 12 days
