Answer:
what sentence
Step-by-step explanation:
Answer: y = 800
Step-by-step explanation:
3(y+200) = 3000
y+200 = 1000 (dividing 3 from both sides)
y = 800
Since multiplying by 0.5 is the same as dividing by 2, the problem is described by the sentence
"Half the sum of a number and 40 equals 200"
Answer:
Hello! Answer: B
Step-by-step explanation:
Because 112 is 70% of 160
3x + 4y = 19
3x + 6y = 33
2y = 14
y = 7
3x + 28 = 19
3x = -9
x = -3
3x + 42 = 33
3x = -9
x = -3
