How can you use 2 x 8 to find 4 x 8?
You double the product of 2x8.2x8 equals 16. 16 doubled which equal 16x2 equals 32.4x8 equals 32.
What is the answer for 5c equals -75?
The 'answer' is the number that 'c' must be, if 5c is really the same as -75.In order to find out what number that is, you could use 'algebra'.First, write the equation, so that you can look at it:5c = -75Now, use the law of algebra that says: "If equals are divided by equals,then the quotients are equal".The left and right sides of your equation are equals. Divide them both by 5,and that law says that the quotients on both sides will be equal:c = -15

What divided by seven equals 4?
28 You can use some basic algebra. Call the number you are looking for m, then m/7=4. Multiply both sides of the equation and you have m=7x4=28 Or you can use "brute force" and make a multiplication table of multiple of 7. When you get to 4 you note, as below, that 7x4=28. Of course this is the same answer as above. 1x7= 7 2x7= 14 3x7= 21 4x7= 28 So 28/7= 4
