Answer:

x=2

y=10.5

z=2.3

w=1.75

Step-by-step explanation:

both sides of each scale have the same weight attached to them so you just have to solve the following equasitions for each scale: 3x+1=7 2y+10=31 2z+2.2=6.7 4w+3/2=17/2

How do I do this ? I don't know how to find the midpoint in this problem

finlep [7]

If point A is the midpoint then that means line segments XA and AY are equivalent so you can set:
3x=5x-6
(now you solve for x)
2x=6
(divide by 2 on both sides)
x=3

So BASICALLY,
XA= 3x= 3(3) = 9
AY= 5x-6= 5(3)-6 =9
So now you know the length of both sides, add those together and you get
XY=18

Help me to do 10(b) answer

antiseptic1488 [7]

Answer:

Step-by-step explanation:

Big circle:

R = radius = diameter ÷2 = 42 ÷ 2 = 21 cm

Area of big circle= πR²

$=\dfrac{22}{7}*21*21=22*3*21\\\\\\= 1386 \ cm^{2}$

Small circle:

Diameter of small circle = radius of big circle = 21 cm

r = 21/2 = 10.5 cm

Area of small circle = πr²

$=\dfrac{22}{7}*10.5*10.5 = 22 * 1.5*10.5\\\\\\= 346 .5 \ cm^{2}$

Area of shaded region = area of big circle - area of small circle

= 1386 - 346.5

= 1039.5 cm²

astraxan [27]

First, distribute 2 to all terms within the parenthesis

2(4x + 5) = 8x + 10

8x + 10 > 7x + 20

Isolate the x. Treat the > like a equal sign. Subtract 7x and 10 from both sides

8x (-7x) + 10 (-10) > 7x (-7x) + 20 (-10)

Simplify

8x - 7x > 20 - 10

x > 10

x > 10 is your answer

hope this helps
