Answer:
choose "infinitely more solutions"
Step-by-step explanation:
Let's solve this system by substitution method
y+1=2x
- 1 = - 1
y = 2x -1 <-- sbstitute this in the next equation
---------------------------------------------------------------------------------
5y+5 = 10x
5(2x -1) + 5 = 10x
10x -5 + 5 = 10x
10x + 0= 10x
- 10x = -10x
0 = 0 <-- infinitely more solutions
The answer should be a) (p+q)*r
Answer:
-2.2
Step-by-step explanation:
By using the equation 5*(4+x)=9, when you isolate x you get -2.2.
4x+2=-2
4x=-2-2
4x=-4
x=-4/4
x=-1
I am working on this in school, this is how we are being taught to do this type of problem:
First, convert the 9.5% to 0.095. Then multiply:
10,000 x 0.095 x 90 = 85,500
So, the answer should be: $85,500 interest.
