Answer:
a. i. x ≤ 25 ii. 16 < x < 35 iii. 25 < x ≤ 95
b. The second and third car seats are appropriate for a 35 lb child.
Step-by-step explanation:
a. Model those ranges with compound inequalities
Let x represent the car seat.
i. A car seat designed for a child weighing up to and including 25 lb is described by the inequality.
x ≤ 25
ii. A car seat designed for a child weighing between 16 lb and 35 lb is described by the inequality.
16 < x < 35
iii. A car seat designed for a child weighing between 25 lb and 95 lb inclusive is described by the inequality.
25 < x ≤ 95
b. Which car seats are appropriate for a 33-lb child?
Since 35 lb is included in the range of the inequalities for the second and third card seats, the second and third car seats are appropriate for a 35 lb child.
Answer:
A
Step-by-step explanation:
If you want to figure out all you have to do is divide 465 by 16.5.
The only equation that shows that is the first one. In equations you need to get the X by itself so you'll have to divide to do that.
It's same if you say something like "You have 4 apples but need to divide them in 2 groups."
Ok so for the first one:
-We know that the 4 angles add up to 360
-3 of the angles are given
-To find the fourth we simply subtract the sum of the 3 angles from 360.
Equation: 120+ 100+ 100 + x = 360
= 320+x= 360
Now by making x the subject
x= 360 - 320
= 40 degrees
The second one follows the same method
150+ 77+ 48+ x =360
275 +x = 360
x= 360-275
x= 85
