Answer:
B
Step-by-step explanation:
You should find the solution for this system of equations (The value of x is the first coordinate for the point of intersection, the value of y is the second coordinate for the point of intersection)
X+y=0.3
y=3x+16.7
use 3x+16.7 instead of y in the first equation(do it to get only x in the first equation)
x+3x+16.7=0.3
4x+16.4=0
4x=-16.4
x=-4.1
y=0.3+4.1=4.4
B
Answer:
49
Step-by-step explanation:
15 + 4 = 19
19 x 2 = 38
38 - 19
Answer:
d option
Step-by-step explanation:
Area of rectangle = length × breadth
Placing the values,
143 m² = length × 6.5 m
length = 143 m²/6.5 m = 22 m.

Answer:
see explanation
Step-by-step explanation:
3x and 144 are adjacent angles on a straight line and sum to 180°
3x + 144 = 180 ( subtract 144 from both sides )
3x = 36 ← value of 3x
divide both sides by 3
x = 12
and
2y - 5 and 95 are vertically opposite angles and are congruent, so
2y - 5 = 95 ← value of 2y - 5
add 5 to both sides
2y = 100 ( divide both sides by 2 )
y = 50
Then
x + y = 12 + 50 = 62
275 divided by 5 is 55. 55 is your answer
