10)
variable : cost of 1 square foot flooring = x
equation :
60x + 80 = 287
60x = 287 - 80
x = (287-80) / 60
11)
variable : doughnut cost = d
equation :
3(1.25) + 6d = 6.90
3.75 + 6d = 6.90
6d = 6.90 - 3.75
d = (6.90 - 3.75) / 6
12)
variable : smaller number = x
equation :
x + x + 1 = -29
2x + 1 = -29
2x = -29 - 1
x = (-29 - 1) / 2
13)
variable : number of shrubs : n
eqution :
n(25) + 110 = 260
25n = 260 - 110
n = (260 - 110) / 25
Answer:
C
Step-by-step explanation:
I chose this answer because in the passage it states that the pyramids served as giant grave markers, so in conclusion I think that the pharohs thought that people would have decency and leave them alone but instead the robbers would rob them. And they figured that the robbers would be afraid because of gods watching over them.
Thanks for the question!
4 - 6 + 6
We can make this easier by doing it one step at a time. First, lets do 4 - 6.
4 - 6 + 6
-2 + 6
Now, solve:
-2 + 6
4
Hope this helps!
Answer:
3.7 < √14 < 3.8
Step-by-step explanation:
First approximation
9 < 14 < 16, so
3 < √14 < 4
Second approximation
14 is closer to 16 than to 9.
Is √14 between 3.7 and 3.8? If so, then
3.7² < 14 < 3.8²
13.69 < 14 < 14.44. TRUE
The inequality is 3.7 < √14 < 3.8.
