Answer:
x = 37
Step-by-step explanation:
3y - 20 + x + 13 = 3x + 9
3y - 16 = 2x
1.5y - 8 = x
2y + 3x + 9 = 180
2y + 3x = 171
2y + 3(1.5y - 8) = 171
2y + 4.5y - 24 = 171
6.5y = 195
y = 30
1.5y - 8 = x
1.5 * 30 - 8 = x
45 - 8 = x
37 = x
Answer:
it have to be C
Step-by-step explanation:
By the Pythagorean theorem

x = √6 cm
Answer:
The third Number line = C
P = - 1 ; Q = 7
Step-by-step explanation:
P = - 1 ; as the tick marks are 1 unit apart ; hence the point P is located either side of - 2 and 0 ; therefore, the point Q is either :
(-2 + 1) = - 1 or (0 - 1) = - 1
Q = 7 ; Q is position on between 6 and 8 ; therefore, the number which falls in the middle of both numbers is 7.
