Answer:
Yes they are equivalent
Step-by-step explanation:
8x + 18 + x = 9x + 18
9(2+x) = 18 + 9x = 9x + 18
Therefore, 8x + 18 + x is equivalent to 9(2+x)
Answer:
-6y^3+7y^2-2
Step-by-step explanation:
(-2y^3+2y^2-9)+(-4y^3+5y^2+7)
-2y^3-4y^3+2y^2+5y^2-9+7
-6y^3+7y^2-2
Answer:
Anthony is incorrect
According to the order of operations(PEMDAS), you must first multiply 10 × 3
which equals 30, then you add 2, which equals 32, finally you subtract 2, which brings you back to 30
10 × 3 = 30
2 + 30 - 2 = 30
Multiple both ratios by a least common denominator
the least common denominator for both is 15
multiply the first ratio by 3/3
9/15=9/15
both are equal because when multiplying by the least common denominator you get the same answer
If i understand you are wanting to find the value of g
so if 2/5 of the unkown value g is equal to -14 you would find out that 1/5 g would be -7 so to find g you times -7 by 5 and get -35
g= -35
