19.5 you can use photo math for math problems like this
Answer:
Step-by-step explanation:
This is a compound inequality that basically states that the X value is greater than or equal to -5, but less than or equal to -1. It is inclusive, because it includes both numbers and therefore should have an equal to sign () instead of just less than or greater than ( < or >).
Answer:
The correct answers are 1, 2, and 3.
Step-by-step explanation:
Ok
1. if the number is greater than 2, it is a solution so 57 is a solution
2. Since it has to be greater than 2, zero is not a solution
3. Since it is greater than 2 and not equal to it, two is not a solution.
4. Since it has to be greater than 2, -2 is not a solution, so <u>false</u>
5. Since it is greater than 2 and not equal to it, 2 is not a solution, so <u>false</u>
<u></u>
The correct answers are 1, 2, and 3.

Answer:
16/3
Step-by-step explanation:
2/-3 and -2/3 are the same
The equation is: -2/3+6
Change 6 into 18/3 by multiplying 6 into 3/3, we do this so that they are similar terms and easier to add.
New equation: -2/3+18/3
switch the equation:18/3-2/3= 16/3
Based on the given parameters of a = 1.7 cubic feet and concrete for first 4 steps as 17 cubic feet, the concrete is required for the first 12 steps is 132.6 cubic feet
<h3>Arithmetic progression</h3>
- First term, a = 1.7 cubic feet
- Sum of first four terms = 17 cubic feet
Sn = n/2 {2a + (n - 1) d}
17 = 4/2{2×1.7 + (4 - 1)d}
17 = 2{3.4 + (3)d}
17 = 2(3.4 + 3d)
17 = 6.8 + 6d
17 - 6.8 = 6d
10.2 = 6d
d = 10.2/6
- Common difference, d = 1.7
Concrete required for first 12 steps;
Sn = n/2 {2a + (n - 1) d}
= 12/2{2×1.7 + (12-1)1.7}
= 6{3.4 + (11) 1.7}
= 6(3.4 + 18.7)
= 6(22.1)
= 132.6
Concrete required for first 12 steps = 132.6 cubic feet
