Answer:
5x - 9 ≥ -28
Simplifying gives:
x ≥ -3.8
Step-by-step explanation:
Nine subtracted from the product of 5 and a number is at least -28
Let the number be x so;
5x - 9 ≥ -28
5x ≥ -28 + 9
5x ≥ -19
x ≥ -19/5
x ≥ -3.8
Answer:
System of equations:
A bar soap costs $0.52 and a sponge costs $0.15
Step-by-step explanation:
Let be "x" the cost in dollars of a bar of soap and "y" the cost in dollars of a sponge.
Based on the information given in the exercise, you can set up the following system of equations:
You can use the Elmination method to solve the system of equations:
1. Multiply the first equation by -3 and the second one by 5.
2. Add the equations.
3. Solve for "x".
Then:
4. Substitute the value of "x" into any original equation and solve for "y":
Hi!
5²·5² = ?
When you solve 5² you multiply 5 · 5. So we could also write this equation as...
5 · 5 · 5 · 5 = ?
Solve
25 · 5 · 5 = ?
25 · 25 = ?
625
Hope this helps! :)
