Answer:
D. 15×4/100×4 = 60/400
Step-by-step explanation:
First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.
Answer:
x=-4
Step-by-step explanation:
-2x+18-1x+4=34
step 1 combine like terms
-2x+-1x=-3x
18+4=22
-3x+22=34
step 2 subtract each side by 22
-3x=12
step 3 divide each side by -3
x=-4
hope this helps (:
Answer:

Step-by-step explanation:
"Like terms" are terms with the same variable or exponents.
You can add or subtract these just like you would with regular numbers.
Examples:
2x + 4x = 6x
5xy + 7xy = 12xy
6 + 5 = 11
