D = 109 - 84 = 134 - 109 = 25
2nd term = 34 + 25 = 59
88 tens = 880
20 tens = 200
880 - 200 = 680
Answer:
you do your letters first then your other math
Step-by-step explanation:
Answer:
42 words
Step-by-step explanation:
To solve just solve 0.25x +1.50 = 12.00 for x
X= weight of TV
y= weight of CD
3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:
3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.
Now plug y= 3.5 back into any equation to get x:
3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5
