Answer:
27 SUVs
Step-by-step explanation:
Let number of ordinary cars be x and SUVs be y
We can write 2 equations and use substitution to solve for the number of SUVs.
<u>"The number of ordinary cars is larger than the number of sport utility vehicles by 59.3%"- </u>
This means that 1.593 times more is ordinary cars (x) than SUVs (y), so we can write:
x = 1.593y
<u>"The difference between the number of cars and the number of SUVs is 16" - </u>
Since we know ordinary cars are "more", we can say x - y = 16
<em>We can now plug in 1.593 y into x of the 2nd equation and solve for y:</em>
<em>x - y = 16</em>
<em>1.593y - y = 16</em>
<em>0.593y = 16</em>
<em>y = 27 (rounded)</em>
<em />
<em>Hence, there are 27 SUVs</em>
Answer:
Expansion for there will be 9 terms.
(a+b) ^n =nco a^n b^o+ nc1 a^(n-1) b^1+nc2 a^(n-2) b^2+nc3 a(n-3) b^3+nc4 a^(n-4) b^4+...........................ncn a^o b^n.
5th term of (2x+y)^8 = ?
5th term is nC4 a^(n-4) b^4
a=2x, b=y, n=8
therefore 8C4 (2x)^(8-4) (y)^4
8!/((8-4)! 4!) (2x)^4 y^4
40320/576 (16 x^4 ) (y^4)
70 (16x^4)(y^4)
1120 X^4 Y^4
Step-by-step explanation:
<span>3x+5y=4...(1)
2x-y=-7...(2)
by(2) : y = 2x+7
subsct in (1) :
3x +5(2x+7) = 4
13x = - 31
x = -31/13
y = 2(-31/13)+7 = 29/13</span>
Answer:
$330
Step-by-step explanation:
So when you factor this the answer would be (1w - 3)(5w + 1) because since 5 is an odd number you have to break it up with us only factores then you find the GCF for 3 and then you have to find the signs that when you multiply them it gives you - 14
