Answer:
Step-by-step explanation:
I'll assume the above equation is: 9 - 7x = 7 - 4(2x+3)
* do distributive multiplication
9 - 7x = 7 - 8x - 12
*move like terms
-7x + 8x = 7 - 12 - 9
* solve for x
x = 7 - 21
x = -14
To check, substitute x by its value -14
9 - 7x = 7 - 4(2x+3)
9 - 7(-14) = 7 -4[2(-14) + 3]
9 + 98 = 7 - 4(-28 +3)
107 = 7 - 4(-25)
107 = 7 + 100
107 = 107
90-25.1=64.9
since complementary angles equal 90
hope this helped
Answer:
The answer is there it is 21 miles/ but if its wrong then below will be right.
27-23= 4+15 = 19 miles
27 needed to be deducted first to find out how many miles it took from Corwen to Mold. Then as we found 4 miles we can then work out Mold to Wrexham = 15 Then add together = 19m
Step-by-step explanation:
its better if you label the 0-C = 27 C-M = 27-23 = 4 then M-W = 15 15+4 =19
