4). x/5 =8
     x = 40
5). 2x/3 = 12
     2x = 36
      x = 36/2 = 18
6). x + 26 =12
      x = 12 - 26 = -14
7).  8x + 1 = -23
      8x = -23 -1
      8x = -24
        x = -24/8 = -3
8). 2x + 5 =15
     2x = 15 - 5
     2x = 10
       x = 10/2 = 5
9). 3x - 1 = -29
     3x = -29 + 1
     3x = -28
       x = -28/3 Or 9.33
10). 8x - 12 = 53
       8x = 53 + 12
       8x = 65
        x = 65/8 Or 8.12
11). 4x + 7 = 25
       4x = 25 - 7
       4x = 18
        x =18/4 = 9/2 Or 4.5

mamaluj [8]

Answer:

m=x+6

Step-by-step explanation:

Let's solve for m.

mx=x(x+6)

Step 1: Divide both sides by x.

2x/x=    x²+6x/x

m=x+6

Hope this helps :)

____  x  ____
60(V)      15

45*15=675
60*?=60
675 DIVIDE BY 60=11.25

Can anyone explain how to do any of this?
pashok25 [27]

Answer:

qn 10. 15mn² - 23m²n +4m³

Step-by-step explanation:

1. distribute 4m through the parenthesis

8mn² - 12m²n + 4m³ - 2n(5m² - 3nm) + nm(n-m)

2. use the commutative property to reorder the terms

8mn² - 12m²n + 4m³ - 2n(5m² - 3mn) + mn(n - m)

3. distribute -2n through the remaining parenthesis

8mn² - 12m²n + 4m³ -10m²n + 6mn² + mn² - m²n

4. collect like terms

8mn² + 6mn² + mn² - 12m²n - 10m²n - m²n + 4m³

5. complete bodmas

15mn² - 23m²n +4m³

that's is how you do it so the answer is

15mn² -23m²n + 4m³

Find dcq pls thanks so much
Diano4ka-milaya [45]

Answer:

arc ABC = 196°

∠DCQ = 47°

Step-by-step explanation:

arc AD = 70°

∠D = 1/2 arc ABC = 98°

arc ABC = 98° * 2 = 196°

arc CD = 360° - arc AD - arc ABC = 360°-70°-196° = 94°

tangent chord angle DCQ = 1/2 arc CD = 1/2 * 94° = 47°
