Answer:
Chinese speakers = 17
English speakers = 8
Difference = 17 - 8
Difference = 9
<u>There will be 9 more Chinese speakers than English Speakers. </u>
Step-by-step explanation:
Answer:
(6, 1)
Step-by-step explanation:
x + 2y = 8
1. subtract 2y to get x alone -- x = -2y + 8
2. insert (-2y + 8) as x
2x - 2 = 10
2(-2y + 8) -2 = 10
3. distribute the 2
-4y + 16 - 2 = 10
4. combine like terms
-4y + 14 = 10
5. subtract 14 from both sides
-4y = -4
6. divide by -4
y = 1
7. plug y into any of the two original equations
x + 2(1) = 8
8. simplify
x + 2 = 8
x = 6
9. check answer with second equation
2(6) - 2 = 10
12 - 2 = 10
(y + 7)^2 = (y + 7)(y + 7)
Multiply all the terms in the first parenthesis to all the terms in the 2nd parenthesis:
y * y = y^2
y * 7 = 7y
7 * y = 7y
7 * 7 = 49
So we have:
y^2 + 7y + 7y + 49
Combine like terms:
y^2 + 14y + 49
4x - 1 = side of square 2x + 1 = length of rectanglex + 2 = width of rectangleSince their perimeters are equal, 4(4x - 1) = 2(2x + 1) + 2(x + 2) 16x - 4 = 4x + 2 + 2x + 410x = 10x = 1If we plug 1 in for x,Each side of the square is 4(1) - 1 = 3The perimeter is thus 12 The length of the rectangle = 2(1) + 1 = 3The width of the rectangle is 1 + 2 = 3The perimeter is this 2(3) + 2(3) = 12 So x = 1 is the verified.
