The secondstep is
2.5 (42 ÷ 3.2 – 2 + 3) - 5.2
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Step 1:
2.5 (42 ÷ 3.2 – 10(0.2) + 3) - 5.2
Step 2:
2.5 (42 ÷ 3.2 – 2 + 3) - 5.2
Step 3:
2.5 (13.125 + 1) - 5.2
Step 4:
2.5 (14.125) - 5.2
Step 5:
35.3125 - 5.2
Step 6:
30.1125
Thus,
The value of the expression is 30.1125.

The value of the expression −x2+6z/y when x=10, y=−2, and z=−5 is -85.
To evaluate the expression when x=10, y=−2, and z=−5, we substitute these values into the expression:
−x2+6z/y
−(10)2+6(-5)/(-2)
−100+(-30)/(-2)
−100+15
= -85
Therefore, when x=10, y=−2, and z=−5, the value of the expression −x2+6z/y is -85.

Answer:
Step-by-step explanation:
{z - some integer}
2z+1 - the smallest number
7(2z+1) - seven times the smallest number
2z+1+2=2z+3 - the middle number
2z+3+2 = 2z+5 - the largest number
2(2z+5) - twice the largest number
7(2z+1) + 2(2z+5) - the sum of 7 times the smallest and twice the largest
7(2z+1) + 2(2z+5) = -91
14z + 7 + 4z + 10 = -91
-17 -17
18z = -108
÷18 ÷18
z = -6
2z+1 = 2(-6)+1 = -12 + 1 = -11
2z+3 = 2(-6)+3 = -12 + 3 = -9
2z+5 = 2(-6)+5 = -12 + 5 = -7
To solve this problem, we denote the smallest odd integer as 'x' and set up the equation 7x + 2(x+4) = -91. By solving this equation, we find that the smallest integer is -15.
To find the three consecutive odd integers, let us denote the smallest odd integer as x; therefore, the next two consecutive odd integers would be x + 2 and x + 4, respectively. The problem states that the sum of seven times the smallest integer and twice the largest integer equals to -91. So, we can translate this into the equation, 7x + 2(x+4) = -91. Solving this gives us x = -15. Hence the smallest integer is -15. The full solution is as follows:
