Base on graph x > -3
so if you multiply both sides by 2 then: 2x > - 6
answer
D. x > - 3; 2x > -6
Hello
Fractions with anything that has 10, 100, 1000 is easy to me from fraction. 18/1000 means from whole # 18 move left the number of 0 which in this case is 3 so the answer is .018If it was 18/100 you would move 2 spaces =.18
Have a nice day
Answer:
C) 7×10^8/(5×10^3)
Step-by-step explanation:
In cubic inches, the volume of a bucket of sand is ...
(π/4)(20 in)²(15 in) = 1500π in³ ≈ 5×10^3 in³
__
The volume of the warehouse is
(250 ft)(80 ft)(20 ft) = 400,000 ft³ = 4×10^5 ft³
The conversion to cubic inches is ...
(4×10^5 ft³)(1728 in³/ft³) = 4×1.727×10^8 in³ ≈ 7×10^8 in³
Dividing the warehouse volume by the bucket volume gives the approximate number of buckets that will fit in the warehouse:
(7×10^8)/(5×10^3) . . . . . matches choice C
Start with x+y=10 and x-y=4
Add the equations to eliminate y:
x+y=10
+ x-y=4
2x =14
So now solve for x:
2x=14 (Divide each side by 2 to get x by itself)
x=7
Now you have solved for x, but you still need to solve for y:
x+y=10
7+y=10 (Subtract 7 from both sides to get y by itself)
y=3
Now you have both x and y but to check it, just plug it into the original equations:
x+y=10 ----> 7+3=10 (That's correct)
x-y=4 ----> 7-3=4 (That's correct)
There's your final answer.
