Point C'(-4,-3) is the image of C(-2, -3) under a translation.

C(-2,-3) moves to C ' (-4, -3)

The x coordinate changes from -2 to -4. So we subtracted -2 from the x coordinate. Algebraically, x becomes x-2

The y coordinates are both -3, so nothing changes here.

The translation rule is (x,y) \to (x-2, y)

This represents a shift of 2 units to the left.

The ratio of boys to girls in a group is 7:1. If there are 66 more boys than girls, work out how many girls there are
nevsk [136]

Answer:11

Step-by-step explanation:

Boys : girls=7:1

Sum of ratio=7+1=8

Let them number of girls be y

Then they number of boys=y+66

Total number of pupils=y+y+66

Total number of pupils=2y+66

Number of girls=(girls ratio)/(sum of ratio) x (total number of pupils)

y=1/8 x (2y+66)

Cross multiply

y x 8=2y + 66

8y=2y + 66

Collect like terms

8y-2y=66

6y=66

Divide both sides by 6

6y/6=66/6

y=11

The number of girls is 11

<span>Any multiple of 9 will give whole number answers. </span>

<span>Let x= 9 </span>

Answer:

68°

Step-by-step explanation:

PRQ = SRQ gives:

3x-8 = 2x+6

x = 6+8 = 14

So PRQ = SRQ = 34

and

PRS = PRQ+SRQ = 68
