Answer:
None.
Step-by-step explanation:
4(x-1)-x = 3(x+5)-11
4x-4-x=3x+15-11
we combine like terms.
4x-x-4=3x+14
3x-4=3x+14
we then isolate the variables.
3x-4=3x+14
+4 +4
3x=3x+18
-3x -3x
0≠18
No solutions
Answer: -2x + 5y = 8
Step-by-step explanation:
Since the lines must be parallel, the slopes must be the same, so keep the coefficients of x and y
Substitute the values of x and y from the given coordinate (6,4) to find the new constant, b, the y-intercept.
-2x + 5y = b
-2(6) + 5(4) = b
-12 + 20 = b
8 = b
Rewrite the original equation substituting the new b for the original -15
-2x + 5y = 8
Answer:
12
Step-by-step explanation:
A= (h)(b)/2 = 4×6/2=12
I got the six for the base and 4 for the height. You multiply 4×6 which is 24 and divide by 2 which is 12
Answer:
9 blocks
Step-by-step explanation:
The total of what John has already walked and the number more he must walk will be equal to the number he has to walk to get to school.
12 + more = 5 + 9 + 7
more = 9 + 5 + 7 - 12 . . . . . subtract 12 from both sides
more = 9
John must walk 9 blocks more.
_____
We recognize that 5+7 = 12, so that last part of the sum totals zero.
