Divide 1 3/4 into 15. I like to change my fractions into decimals, so I will be using the decimal form of 1 3/4, which is 1.75

15 ÷ 1.75 = 8.571

Since there is still some left over, you would need to add one more roll. Therefore, you would need 9 rolls.

I need help with this

System:
y ≤ -x + 4
y > \frac{1}{3}x

Notes:
1. inequalities are expressed in slope-intercept form. y = mx + b
2. the second inequality uses the greater than inequality symbol rather than the greater or equal to symbol due to the broken line.
3. All points in the shaded region will satisfy both inequalities. Point outside the shaded region will not satisfy both inequalities.

Use compatible numbers to find two estimates 1322 divided by 18
prisoha [69]
Compatible numbers is used to find estimate to a sum. The numbers are chosen because its 'simplicity' when they are multiplied, divided, added or subtracted.

Estimate one:

We can decrease the value 1322 to 1320 and 18 to 15
Then do the sum = 1320÷15 = 88
This estimate is not far from the actual answer 1322÷18 = 73.44..

Estimate two:

We can increase 1322 to 1330 and 18 to 20
Then do the sum 1330÷20=66.50
This estimate is also not far from the actual answer 73.44...
