The other number is -2.
Step-by-step explanation:
Step 1; Assume the other number is x. So 4 times the difference between x and 1 is equal to x-10. So we formulate the equation as
4(x -1) = x - 10,
4x - 4 = x - 10,
Transferring the unknown values to the left side and keeping the known values on the right we get
4x - x = -10 + 4,
3x = -6.
x = -2.
So the other number is -2.
Step 2; To check if we got the right number we substitute it into the given equation and see if it matches.
Equation is 4(x -1) = x - 10 substituting x=-2 we get,
4(-2 -1) = -2-10, - 12 = -12. Both sides are equal so the other number is -2.
Option A is the correct answer.

Answer:
Yes. Bc 8 have a negative sign infront of it so 9 greater
Since the question wants to know how many ingredients she used, All we have to do is add them.
So as the question says, she used 6/10 flour, 3 eggs, and 4/5 sugar.
Now we have two fractions in this scenario. Let's make them have the same denominator. Either we divide 6/10 by 2 or multiply 4/5 by 2. Let's multiply.
4/5 × 2 = 8/10
Now we have 6/10, 3, and 8/10
Lets add them together.
3 + 6/10 = 3 and 6/10
Now 3 and 6/10 + 8/10 = 4 and 4/10
Simplify even further...
and your answer will be 4 and 2/5
