Answer:
x = 2
y = 1
Step-by-step explanation:
-2x-3y=-7, y=6x-11
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-2x - 18x = -40
-20x = -40
<u><em>x = 2</em></u>
y = 6(2) - 11
y = 12 - 11
<u><em>y = 1</em></u>

Area of the figure = 27 square units
Solution:
Number of full squares shaded = 24
Number of half squares shaded = 0
Number of more than half square shaded = 3
Number of less than half square shaded = 4
Area of the figure = Number of full square + Number of more than half square
+ Half of number of half squares
= 24 + 3
= 27 square units.
Area of the figure = 27 square units
Answer:
c = 6.5, a = 11.6
Step-by-step explanation:
2a + 3c = 42.7
3a + 5c = 67.3
Elimination
(2a+3c = 42.7)*3
(3a+5c = 67.3)*2
(1) 6a+9c = 128.1
(2) 6a+10c = 134.6
(2) - (1)
c = 6.5
Substitue 'c' in any of the equation
2a + 3(6.5) = 42.7 or 3a + 5(6.5) = 67.3
2a + 19.5 = 42.7 3a + 32.5 = 67.3
2a = 42.7 - 19.5 3a = 67.3 - 32.5
2a = 23.2 3a = 34.8
a = 11.6 a = 11.6
