Answer:

look its really simple like if there is written the father age is two times than its son and its is also said sum of their age becomes 25 then

Step-by-step explanation:

solution,

let father and son age be x and y

2x =y ---------------(i)

x+y=25----------------(ii)

now,

putting the value of y in equation two we get,

x+(2x)=25

3x=25

x=25/3

x=8 yrs ( using round off)

again,

2x = y

2×8=y

16=y

therefore, father age is 16 and son age is 8

Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the

bagirrra123 [75]

Answer:

$c = -6$

$d = -1$

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

$a = (3,5)$ --- Point on A

$a' = (-3,-6)$ --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

$(x,y) \to (x,-y)$

So, we have:

$(3,5) \to (3,-5)$

Next, is to calculate the translation from $(3,-5)$ to $(-3,-6)$

This is calculated using:

$3 + c = -3$

and

$-5 + d = -6$

So, we have:

$3 + c = -3$

$c = -3-3$

---- i.e. Shift by 6 units to the left

$-5 + d = -6$

$d = 5 - 6$

$d = -1$ --- i.e. Shift by 1 unit down

SIZIF [17.4K]

Answer:

y-9=1/2(x-8)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-9)/(-2-8)

m=-5/-10

m=1/2

y-y1=m(x-x1)

y-9=1/2(x-8)

1. A tank is 3/5 full of water. After 330 litres of water is drawn out, it becomes 2/7 full. Find the capacity of the tank in li

Andreas93 [3]

Answer:

1050

Step-by-step explanation:

Let x = full capacity

$\frac{3}{5} x=\frac{2}{7} x+330$

Move the variable to the left side by subtracting both sides by $\frac{2}{7} x$

$\frac{3}{5} x-\frac{2}{7}x=\frac{2}{7} x+330 -\frac{2}{7}x$

$\frac{3}{5} x-\frac{2}{7} x=330$

Combine the like terms (don't forget about common denominator)

$\frac{21}{35} x-\frac{10}{35} x=330$

$\frac{11}{35} x=330$

Multiply both sides by $\frac{35}{11}$ to isolate the x

$(\frac{35}{11})\frac{11}{35} x=330(\frac{35}{11})$

$x = 1050$
