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

How can you use 3x7 to find 6x7?
To find 6x7 using 3x7, you can simply double the result of 3x7. This is because multiplication is distributive over addition, meaning that multiplying a number by a sum is the same as multiplying the number by each addend and then adding the products. In this case, 6x7 can be thought of as (3+3)x7, which equals 3x7 + 3x7, or 21 + 21, which equals 42.

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
