Goals=30
the ratio is 6 units to 7 units
goals=6 units
goals=30
30=6 uints
divide by 6
5=1 unit
so miss=7 units
5 per unit times 7 units=35
answer is 35 miss

He missed 26 times. First you do 6 divided by 7 times 100 to get 86(rounded). Then you do 30 divided by 100 to get .3 times the 86 to get 26.

Show that x + y : x - y= 3 : 2

insens350 [35]

Answer:

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore, x + y : x - y= 3 : 2 is proved.

Step-by-step explanation:

Given

x + y : x - y = 3 : 2

$x + y = 3$

$x - y = 2$

Solving to find x and y

$\begin{bmatrix}x+y=3\\ x-y=2\end{bmatrix}$

$x-y=2$

$-$

$\underline{x+y=3}$

$-2y=-1$

$\begin{bmatrix}x+y=3\\ -2y=-1\end{bmatrix}$

solve for y

$-2y=-1$

Divide both sides by 2

$\frac{-2y}{-2}=\frac{-1}{-2}$

$y=\frac{1}{2}$

$\mathrm{For\:}x+y=3\mathrm{\:plug\:in\:}y=\frac{1}{2}$

$x+\frac{1}{2}=3$

$x+\frac{1}{2}-\frac{1}{2}=3-\frac{1}{2}$

$x=\frac{5}{2}$

$x=\frac{5}{2},\:y=\frac{1}{2}$

Thus,

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore, x + y : x - y= 3 : 2 is proved.
