Find the value of x, given that the m∠2=2x+16

a) -11
b) 11
c) 10
d) 12

Answer:

41

Step-by-step explanation:

the answer can vary between x=−1 or x=2 or x=−3 or x=3

explanation:

x4−x3−11x2+9x+18=0

Step 1: Factor left side of equation.

(x+1)(x−2)(x+3)(x−3)=0

Step 2: Set factors equal to 0.

x+1=0 or x−2=0 or x+3=0 or x−3=0

x=−1 or x=2 or x=−3 or x=3

Answer:

= 2t + 9

or 9 + 2t

Answer:

2t + 9

Step-by-step explanation:

5 + 4 = 9

3t - 1t = 2t

Answer:

780

Step-by-step explanation:

We want to use partial quotients in the division problem 858 ÷ 26.

In partial quotients method, what we do is to repeatedly subtract from the dividend easy multiples of the divisor.

In this case, the dividend is 858 and the divisor is 26.

Thus, the first easy multiple of the divisor we can use will be 30 because 30 × 26 = 780 yields the closest value to 858.

Therefore, the best choice for first number to subtract is 780

Answer: 780

Step-by-step explanation:

The best choice for the division problem will be 780.

[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.

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.

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

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.

Answer:

p = 7

Step-by-step explanation:

set the expressions = to each other

4(n+7) = 4(n+p)

distribute the 4 on both sides(multiplying the numbers on the inside)

4n+28 = 4n+4p

subtract the 4n from the right and left

28 = 4p

divide by 4

p = 7

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

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

Answer:

  x ≥ 16  or  x < 0

Step-by-step explanation:

You want ...

  (x -4)/x ≥ 3/4

  4(x -4) ≥ 3x . . . . . . multiply by 4x (requires x > 0)

  4x -16 ≥ 3x

  x ≥ 16 . . . . . . . . . . add 16-3x

__

For x < 0, multiplying by 4x gives ...

 4(x -4) ≤ 3x

  4x -16 ≤ 3x

  x ≤ 16 . . . . . and x < 0

__

There are two sets of solutions:

  x < 0  or  x ≥ 16
