Answer:
x = 7 ; y = 9
Step-by-step explanation:
Given the system of equation :
y = 2x - 5 - - - (1)
-x + y = 2 ___(2)
From (1)
y = 2x - 5
Put y = 2x - 5 into (2)
-x + 2x - 5 = 2
-x + 2x = 2 + 5
x = 7
We can then solve for y;
Substituting x = 7 into. Equation (1)
y = 2x - 5
y = 2(7) - 5
y = 14 - 5
y = 9
Hence ;
x = 7 ; y = 9
Answer:
Fraction form= 81/8 Decimal form= 10.125
Step-by-step explanation:
Simplify the expression
17: 900 because 3,000 + 900 + 40 +7 is 3,947 or 3,947-3,000-40-7= 900

Answer:
Separate it into smaller figures.
Step-by-step explanation:
The figure can be separated into a triangle on the top, and 2 trapezoids on the middle and the bottom.
The area of the triangle is bh/2, which is (4 x 6)/2, which is 12.
The area of the trapezoid in the middle is .5(b1+b2)h, which is .5(6+4)3, which is 15.
The area of the trapezoid on the bottom is .5(6+5)2, which is 11.
Now, add them to get 12+11+15 which is 38.
