Question

_____+90 = 150

we can expect the estimate to be ____ than the actual sum.

Answer 1

To solve the equation \( x + 90 = 150 \), we can isolate \( x \) by subtracting 90 from both sides:

\[
x = 150 - 90 = 60
\]

Now we can interpret the second part of your statement. If you are estimating \( x \), you might round it or make an approximation. If, for example, you estimate \( x \) as 60 (exact) or a rough approximation close to it, if you are using a different estimation method, it might lead to different results.

If you are estimating \( 60 \) downwards (say to 50) or rounding it differently, we can expect that \( 50 + 90 = 140 \), which is less than \( 150 \).

So, if we are estimating \( x \) below its actual value, we can expect the estimate to be **less** than the actual sum.

**Final response:**
We can expect the estimate to be **less** than the actual sum.
