How does 4/15=14/n? What does n equal?

Answers

4/15 = 14/n

4 * n = 14 * 15

4n = 210 / : 4

n = 52,5

$(4)/(15)=(14)/(n)=>4n=14*15=>4n=210=>n=210:4=>n=52,5$

What is 25/30 + 10/30 (25/30 + 10/30 is fraction)I need the answer bc tomorrow is school and where gonna give the homework to or teacher

Answers

Step-by-step explanation: To simplify the expression 25/30 + 10/30, we first need to find a common denominator. The least common multiple of 30 and 30 is 30 itself, so we can multiply all the fractions by 30. This gives us:

(25/30)(30/30) + (10/30)(30/30) = 75/90 + 10/90

Next, we add the fractions:

75/90 + 10/90 = 85/90

Therefore, 25/30 + 10/30 = 85/90.

If an average 7th grade student weighs 91 pounds and Hugo the Elephant weighs 18,130 pounds, about how many average 7th grade students would be needed to equal the weight of Hugo?

Answers

Divide 18,130 by 91 and you get 199.23 so it is 199 students.

The elephant weighs 18,130, and we want to see how many seventh graders weighing 91 pounds it will take to equal the weight of the elephant.

To find our answer, we divide 18,130 by 91.

18,130÷91 = 199.2307

Since you said about how many average 7th grade students, it means you only need an estimate, not an exact number.

The final answer is 199 average seventh-grade students.

Three is a zero of the equation x^3−4x^2−3x+18=0. Which factored form is equivalent to the equation?

Answers

Answer:

$x_1=-2,\ x_2=x_3=3\n \n(x+2)(x-3)^2=0$

Step-by-step explanation:

Consider the equation

$x^3-4x^2-3x+18=0$

The zeros of the equation can be the divisors of 18:

$\pm 1,\ \pm2,\ \pm3,\ \pm 6,\ \pm 9,\ \pm 18$

Check them:

$1^3-4\cdot 1^2-3\cdot 1+18=1-4-3+18=10\neq 0\n \n(-1)^3-4\cdot (-1)^2-3\cdot (-1)+18=-1-4+3+18=16\neq 0\n \n2^3-4\cdot 2^2-3\cdot 2+18=8-16-6+18=4\neq 0\n \n(-2)^3-4\cdot (-2)^2-3\cdot (-2)+18=-8-16+6+18=0$

So, x=-2 is zero. Now

$x^3-4x^2-3x+18\n \n=x^3+2x^2-6x^2-12x+9x+18\n \n=x^2(x+2)-6x(x+2)+9(x+2)\n \n=(x+2)(x^2-6x+9)\n \n=(x+2)(x-3)^2$

Thus, x=3 is the second root (of multiplicity 2)
