Three less than half of a number is - 1. Find the number.

Answers

Answer 1

Answer:

x = 4

Step-by-step explanation:

Three less than half of a number is -1

The Half Of A Number means the number can be anything, so we can use "x." However, it is half so it would become: 1/2x.

Three less than means it is minus three, therefore becomes: 1/2x-3

However, three less than half of a number is (or in other words is equal too) -1,  so the overall equation is

1/2x - 3 = -1

first, add three on both sides to get:

      1/2x = 2

multiply two on both sides to get:

     x = 4

Answer:

Option (A) and Option (B)

Step-by-step explanation:

Trinomial is a polynomial having three terms.

Option A

[tex]\frac{5}{7}y^3+5y^2+y[/tex]

Number of terms = 3

So it's a trinomial.

Option (B)

x⁴ + x² + 1

Number of terms = 3

It's a trinomial.

Option C

6x² + 0.5y²

Number of terms = 2

It's a binomial.

Option D

x² + 3

Number of terms = 2

It's a binomial.

Option E

x¹¹

Number of terms = 1

Monomial

Option F

8x

Monomial.

Therefore, Option (A) and Option (B) are the correct options.

Transfer into algebraic symbols: 11 less than the square of a number. Use x to represent the number.

Answers

Answer:

[tex]11-x^2[/tex]

Step-by-step explanation:

"11 less than the square of a number" can be written as an algebraic inequality as → 11 < x².

What is inequality?

An inequality compares two numbers or expressions. For example, we can write -

2x + 3 > 5

2x + 9 < 1

Given is the mathematical statement as -

" the square of a number is greater than 11"

We can write the mathematical statement as an algebraic inequality as follows. Let the number be {x}. We can write -

11 < x²

Therefore, "11 less than the square of a number" can be written as an algebraic inequality as → 11 < x².

Answers

Total calories in  4 grams of fat, 3 grams of protein and 3 grams of carbohydrate is 56

What is the unitary method?

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: 4 grams of fat, 3 grams of protein and 3 grams of carbohydrate

Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

Thus total calories from given diet is = 4×4+4×3+9×3

                                                             =16+12+27

                                                            =56

Hence, Total calories in  4 grams of fat, 3 grams of protein and 3 grams of carbohydrate is 56

Bob needs to read 3 novels each month. Let N be the number of novels Bob needs to read in M months, Write an equation relating N to M. Then use this equation to find the number of novels Bob needs to read in 17 months.​

Answers

Answer:

Equation: n=3m; Bob needs to read 51 novels over 17 months.

Step-by-step explanation:

Since the number of novels Bob needs to read (n) depends on the amount of months (m) we can say that n is the dependent variable and m is the independent. Since x is always independent and y is always independent we can say that m is going to stand for x and n is going to stand for y. Each month Bob reads 3 novels so we can write the equations as n=3m. To find out how many books he needs to read in 17 months plug it into the equation. n=3(17) -------------------> n=51
