Answer: 39
Step-by-step explanation:
7⋅8−3⋅6+1
Multiply 7 and 8 to get 56.
56−3×6+1
Multiply 3 and 6 to get 18.
56−18+1
Subtract 18 from 56 to get 38.
38+1
Add 38 and 1 to get 39.
39
Hope i helped let me know if i made it make sense
Answer:
x=3, y=1
Step-by-step explanation:
2x+y =7
3x-4y =5
Multiply the first equation by 4 so we can eliminate y
4(2x+y =7)
8x +4y =28
Add this to the second equation
8x +4y =28
3x-4y =5
----------------
11x = 33
Divide by 11
11x/11=33/11
x=3
Now we still need to find y
2x+y=7
2(3)+y =7
6+y=7
Subtract 6 from each side
6-6+y=7-6
y= 1
3 dimes= 30 cent
4 pennnies= 4
30+4= 34 cents
Answer:
-5/2
Step-by-step explanation:
First, you want to get the equation into the Y=mx+b formula, and my m will be the slope of the line.
So in our case, we get Y= -5/2x+3/2 so my slope is -5/2
