Answer:
the answer is b
Step-by-step explanation:
X=9
DBC= 54°
The given angle is 90°, so we can add the other two given equations to equal 90.
7x-9+4x=90
1) Combine like terms
11x-9=90
2) Add 9 to both sides
11x=99
3) Divide 11 on both sides
x=9
Now to find the angle:
7x-9
1) Plug 9 in for x (which is what we just solved for)
7(9)-9
2) multiply
63-9
3) subtract
54
m= 54°
Answer:
6 shirts (with 1 jacket and $5 left)
Step-by-step explanation:
Since he's already committed to the jacket, the $18 for that is already gone, so of the $95 he came with, $95 - $18 = $77 remains for shirts. He can buy as many $12 shirts as 'fit' in $77, i.e. the quotient of $77 / $12 = Q 6 R 5, i.e. 6 shirts at $12 each for 6 * 12 = $72 in shirts with $5 left over
