The ages of Edna, Ellie, and Elsa are consecutive integers. The sum of their ages is 108. What are their ages?

1 answer:

7 0

All I did was guess and check. I started with the 30s because their sum would be nine and there might be a one to carry to make it 10. After many tries (well, not many, I'm just being dramatic) I got 35, 36, and 37. Hope I helped.

Answer:

42 degrees

Step-by-step explanation:

Angles in a triangle equal 180

180-(37+90)=53

Angles on a line equal 180

180-53=127

127=3b+1

126=3b

b=42

Find a vector function, r(t), that represents the curve of intersection of the two surfaces. the paraboloid z = 7x2 + y2 and the

Akimi4 [234]

Letting $x=t$ , we get $y=3x^2=3t^2$ and $z=7x^2+y^2=7t^2+(3t^2)^2=7t^2+9t^4$ , so we can parameterize the intersection by

$\mathbf r(t)=\langle t,3t^2,7t^2+9t^4\rangle$

where $-\infty$ .

Can you simplify 3(x+2) = 3x+6 in distributive property

Vanyuwa [196]

Hello XD

3(x+2) = 3x+6

Distributive property

(3)(x)+(3)(2) = 3x+6

3x+ 6 = 3x+6

Now subtract 3x from both sides

3x+6-3x = 3x+6-3x

6=6

Subtract 6 from both sides

6-6 = 6-6

0=0

In this case the answer is : All real numbers are solution
