Answer:
2,880
Step-by-step explanation:
P + 60N = x
1500 + 60(23) = x
1500 + 1380 = x
2880 = 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
Answer:
The last one
Step-by-step explanation:
The standard method for solving an equation like 3x + 5 = 26 is to use
the Subtraction Property of Equality and then the Division Property of
Equality.
3x + 5 = 26
you would have to subtract first to get your answer
so subtract 5 on both sides
3x= 21
then u would have to divide 3 by both sides to get the x alone/ isolated
x= 7
and that is why u should use " Subtraction Property of Equality and then the Division Property of Equality, " as your method.
Her house is 24 feet tall = 24*12 inches = 288 inches
SO, 288/8 = 36 (Scaling factor)
5feet * 12 inches/feet = 60 inches
60 inches /36 = 1.667 inches.................< Figurine
That in standard form would be 12
