First you had to multiply with negatives seven and negative five. You can also multiply by the numbers.

-7*-5=-35

Final answer: \boxed{=-35}

35/5=7

7*5=35

5*7=35

35/7=5

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Hello!

Let’s do it step-by-step, shall we? Don’t worry! These problems can be a bit tricky but you’ll get it in no time! It’s really simple.

So, we have (-7)(-5)

This means that the problem will be multiplied because of the parentheses. They substitute the multiplication sign.

So, we have -7 (multiplied by) -5= 35

So your answer would be 35. Hope this helps :) and good luck!

Determine the radius, to the nearest inch, of a large can of tuna fish that has a volume of 66 cubic
Mnenie [13.5K]

The radius of can is 2.524 inches

<em><u>Solution:</u></em>

Given that large can of tuna fish that has a volume of 66 cubic  inches and a height of 3.3 inches

To find: Radius

Given a large can of tuna fish, we know that can is generally of cylinder shape, we can use the volume of cylinder formula,

<em><u>The volume of cylinder is given as:</u></em>

\text{ volume of cylinder}= \pi r^{2} h$

Where,

"r" is the radius of cylinder

"h" is the height of cylinder

\pi is a constant equal to 3.14

Substituting the given values in above formula,

66 = 3.14 \times r^2 \times 3.3\\\\66 = r^2 \times 10.362\\\\r^2 = \frac{66}{10.362}\\\\r^2 = 6.369\\\\r = 2.524

Thus the radius of can is 2.524 inches

Can please cross multiply this for me :)
Alchen [17]
64 x 100 = 6400
11 x x = 11x
I’ll solve this out for you
11x = 6400
Divide 11 from both sides
x = 581.8
Hope this helps!
