Answer:

Step-by-step explanation:

We have to write an equation to represent the relationship "a number decreased by negative 7 is the same thing as 48

Let the unknown number be x.

A number decreased by 7 = $x-7$

Since this equals 48, algebraic equation would be

$x-7=48$

Note: We can solve this by adding 7 to both sides to get x=55

If you have 16 cups of sugar , 2 cups of sugar for every batch of cookies , but you have to save 6 cups of sugar for something e

sesenic [268]

The first step we want to take here is to subtract 6 cups of sugar since we'll need it for something else, leaving us with 10 cups of sugar. It takes 2 cups of sugar for every batch of cookies, so you're going to divide 10 by 2. Luckily, 2 is a multiple of 10 so it's a whole number. By dividing, we get 5. So, we can make 5 batches of cookies while still saving 6 cups of sugar for something else.

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as old as Ishaan.

bixtya [17]

So, the 2 equations would be.... B -12 = I and (B - 3) = 4(I - 3) the second sentence is irrelevant.
B - 3 = 4 (I) - 12
B - 3 = 4B - 48 - 12
B - 4B = -60 + 3
-3B = -57
B (Ben) = 19
Ishaan is 7

Hope this helps!
