Answer:
-All integers are whole numbers.
-All rational numbers are natural numbers.
Step-by-step explanation:
It would be b. In all, he has $100 to spend since $50+$25+$25=$100. We have x people coming and he has to spend $2.50, $1.50, and $3.00 per person, respectively. The phrase "per person" indicates we must multiply, so we have to multiply each value by "x." To find out how much money he has left, we must subtract. All of this put together is 100-(2.50x+1.50x+3.00x).
Add the like terms and you get 7x. Your final expression would be
100-7x, which is answer choice b.
Answer:
x = 35°
Step-by-step explanation:
A triangle = 180°
The 95° is outside of the triangle so it must be smaller.
So say it is 85°
85 + 60 = 145
180 - 145 = 35
Step-by-step explanation:
65 + (y + 9) = 180 ---------- Sum of angles on a
straight line
y + 65 + 9 = 180
y + 74 = 180
y = 180 - 74 = 106
6x + 7 = y + 9 ----------- Alternate angles
But y = 106,
6x + 7 = 106 + 9
6x = 115 - 7
x = 108/6 = 18
