For this one I'm going to assume that 4 7a means 4 * 7a...
(8 + 7a) + 4 * 7a =
8 + 7a + 28a =
8 + 35a
If I read it wrong and 4 7a is actually 47a then...
(8 + 7a) + 47a =
8 + 54a =
2(4 + 27a)

Answer: <u>3.7</u>
Step-by-step explanation: 3.706, but since you need it rounded to the nearest tenth its 3.7. If you put both equations on a graph, they intercept. We use the x coordinate in this intersection as the answer.
Answer:
the answer would be anything 11 and under (11,10,9,8,7,6,5,4,3,2,1,0)
Step-by-step explanation:
This is because if n+5 is less than or equal to 16 then 11+5=16 so that is equal to and less than would be using any number less than 11
hope this helps ;)
This is an easy one!
Three times a number = 128
3x = 128
x = 128/3
x = 42.66666.
Hope this helps!
