Answer:
x=0, y=2. (0, 2).
Step-by-step explanation:
3x+2y=4
8x-3y=-6
---------------
3(3x+2y)=3(4)
2(8x-3y)=2(-6)
-----------------------
9x+6y=12
16x-6y=-12
----------------
25x=0
x=0/25
x=0
3(0)+2y=4
0+2y=4
2y=4-0
2y=4
y=4/2
y=2
Answer:
0.03919
Step-by-step explanation:
You take 1.984+1.96=3.944
3.944-0.025=3.919
3.919 into the percentage =0.03919
Answer:
(x, y) = (1, 3)
Step-by-step explanation:
given the 2 equations
x + y = 4 → (1)
y = 3x → (2)
Substitute y = 3x into (1)
x + 3x = 4
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 into (2) for corresponding value of y
y = 3 × 1 = 3
solution is (1, 3 )
Answer:
The correct answer is option d. 576 ft^2
Step-by-step explanation:
From the figure we can see that a prism
<u>To find the surface area</u>
Surface area = Base area + area of 2 triangles + Two side area
Base area = length * breadth = 15 * 12 = 180 ft^2
Area of triangle = bh/2 = (12 * 8)/2 = 48 ft^2
Area of two triangle = 48 * 2 = 96 ft^2
Area of one side = 15 * 10 = 150 ft^2
Area of two side = 2 * 150 = 300 ft^2
Surface area = 180 + 96 + 300 = 576 ft^2
The correct answer is option d. 576 ft^2
