-3x + 7x = -12
You need to add like terms.
4x = -12
Then, you need to divide both side by 4.
x = -3
So the answer is:
A) x = -3
Answer:
A) 9
Step-by-step explanation:
No. of hours required: 4×27 = 108
If 6 machines working:
108÷6 = 18 hours
27 - 18 = 9 hours fewer
Final answer:
The value of the expression is 31.
Step-by-step explanation:
Substitution is a process of putting the values of variable in the expression.
Given: p=17 and q=3
To find: value of 2p-q
We will substitute the values and simplify.
Putting the values of variables in the expression as
2p-q = 2x17-3 =34-3 = 31

The height of the cone is 24 cm.
<h3>How is the slant height calculated?</h3>
The distance along the curved surface, measured from the edge at the top to a point on the circumference of the circle at the base, is known as the slant height of an object (such as a cone or pyramid). In other words, the slant height, represented either as s or l, is the shortest distance that may be traveled along the surface of the solid.
Slant height(l)=26cm
Radius(r)=10cm
It is known that, 
Here, h is the height of the cone.
On substituting the values,





h=24

Answer:
0
No other rational number is its own reciprocal. We know that there is no rational number which when multiplied with 0, gives 1. Therefore, rational number 0 has no reciprocal or multiplicative inverse.
