1. -8.86
2. 17.5
3. -6.12
4. 1.66
5. 11/24
6. 4/5
7. 14
Step-by-step explanation:
1. -5.51-3.35=-8.86
2. -59.5/-3.4=17.5
3.0.85*-7.2=-6.12
4. -0.59+2.25=1.66 (The double negatives become positive)

Answer:
The required model is
60 pounds of concrete each bag make.
Step-by-step explanation:Consider the provided information.
Let the number of concrete bags are used is represented by y.
Part (A)
3.5 bags of concrete mix for a new set of stairs and 2.25 bags of concrete mix for a garden wall.
This can be written as:
Timothy mixed 345 pounds of concrete in all.
Therefore,
Hence, the required model is
Part (B) Solve for y. How many pounds of concrete does each bag make?
Consider the above equation.
Solve the equation for y as shown.
Add the like terms.
Divide both the sides by 5.75
Hence, 60 pounds of concrete each bag make.

Step-by-step explanation:
Given that :
Number of stickers collected per week = 89
Number of weeks for which stickers were being collected = 28
To obtain the total number of stickers collected, we take the product of the number of weeks for which the stickers were beug vcilled and the number of stickers collected per week
The number of stickers collected :
89 * 28 = 2492
2492 = 2500 ( nearest hundred)
