Answer:y+2.9=11, 2y+1=17.2, 28.4-y=20.3
Step-by-step explanation:
Answer: Choice A) Add 3.8 to both sides of the equation
Explanation:
If we knew the value of w, then we would replace it and apply PEMDAS.
However, we don't know the value of w, so we undo each step of PEMDAS going backwards.
We start with the "S" of PEMDAS, and undo the subtraction. To undo subtraction, you apply addition. To undo that "minus 3.8" we add 3.8 to both sides.
Answer:
the answer is 11.7 because you round up the decimals
Answer: a = 18
explanation:
2(a + 10) = 56 -> distribute the 2
2a + 20 = 56 -> subtract 20 from both sides
2a = 56 - 20
2a = 36 -> divide both sides by 2
a = 18
A = B+32
B = 5C
A = 5C+32
C has d dollars so replace d for c
A = 5d+32
