Which variable expression represents the word phrase? the sum of 10 and the product of 7 and a number a.10−7y b.10y + 7 c.10 + 7y d.10 + (y ÷ 7)

Let's assume

that number as y

the product of 7 and a number means multiplication of 7 and y

so,

the product of 7 and a number=7y

the sum of 10 and the product of 7 and a number means addition of 10 and 7y

so, we get

the sum of 10 and the product of 7 and a number is 10+7y

so, option-CAnswer
