Answer:
-11.7
Step-by-step explanation:
3.3+5(-7 + 4)
we apply distributive property
3.3+5*(-7) + 5*(4)
we know:
+ * - = -
+ * + = +
so we have:
3.3 -35 + 20
3.3 - 15
-11.7
Answer:
Eight times the sum of a number and 2 is equal to 7.
times = multiply
sum = ()
and = +
SO..
8(w + 2 ) = 7
500 (non smokers)÷ 25(random students out of the group)= 20 inches.
20 inches ÷ 74 inches= 3.70
