we can determine the value of this number by setting an equation
the sum of the number and 7, multiplied by 3, is equal to 8 plus the number.
making x= the unknown number, we can say:
3(x+7) = 8 + x
now we can distribute the 3 and solve for x
3x+21 = 8+x
2x+21=8
2x= -13
x = -6.5
hope this helped
Answer:
The length of the line segment is 13 units
Step-by-step explanation:
The line segment joining the two points is horizontal since the y co-ordinate is the same.
For a horizontal line, the length of the line segment is simply the difference between the x co-ordinate values.
In this case we have;
7 - (-6) = 7 + 6 = 13
Therefore, the length of the line segment is 13 units
Any whole number or number that can be written as a fraction
Answer:
40.5
Step-by-step explanation:
Since QS is an angle bisector then PQs and SQR are similar. Using the similarity theorem;
PQ/PS = QR/SR
45/20 = x/18
Cross multiply
20x = 45 * 18
20x = 810
x = 810/20
x = 40.5
Hence the value of x is 40.5
Answer:
General conditions of congruency of triangles
Step-by-step explanation:
As no triangles are given, explaining the general rules to apply in congruency of all triangles.
Triangles are congruent on the basis of following conditions :
- SSS : All 3 sides of two triangles are equal
- SAS : 2 sides & angle between them, of two triangles are equal
- ASA : 2 angles & corresponding side, of two triangles are equal
- HL : Hypotenuse & Leg of two right angled triangles are equal
