The Simplification of the following expression is;

  • m = -30/7
  • v = -8.8
  • x = 3
  • u = -2.49
  • a = -3/70

<h3>Simplification</h3>

7/8m - 4/7 - 5/6m = - 3/4

7/8m - 5/6m = -3/4 + 4/7

21m-20m/24 = -21+16/28

1/24m = -5/28

m = -5/28 ÷ 1/24

= -5/28 × 24/1

= -120/28

m = -30/7

4.3v + 10.75 - 4v = 8.11

0.3v = 8.11 - 10.75

0.3v = -2.64

v = -2.64/0.3

v = -8.8

9/7 + 9/7x - 6/7x =0

9/7x - 6/7x = - 9/7

(9-6)x /7 = 9/7

3/7x = 9/7

x = 9/7 ÷ 3/7

= 9/7 × 7/3

= 9/3

x = 3

6.9u - 2 - 3.2u - 10 = 2.8

3.7u = 2.8 - 12

3.7u = -9.2

u = -9.2/3.7

u = -2.49

8/5 = - 4a + 7/5 - 2/3a

8/5 - 7/5 = -4a - 2/3a

8-7/5 = -12a-2a/3

1/5 = -14/3a

a = 1/5 ÷ -14/3

= 1/5 × -3/14

a = -3/70

The perimeter of a rectangle is 20 ft. The width 8th 4 ft less than the length. Find the dimensions of the rectangle
Gala2k [10]
Perimiter is 20ft
width is
what
do you mean the width is  8 feet less than the length? or 4ft less?

anyway

P=2(L+W)
20=2(L+W)
divide by 2
10=L+W
and
L=10-W

width is 4ft less than length (I assuming)
W=-4+L
repalce W with -4+L
L=10-(-4+L)
L=10+4-L
L=14-L
2L=14
L=7
W=-4+L
W=-4+7
W=3

it is 7ft by 3ft

Find the value of b in the graph of y=3x+b if it is known that the graph goes through the point: N(0,5)
tino4ka555 [31]

Answer:

I believe b is 5.

Step-by-step explanation:

When you place the points in the values, you get 5=3(0)+b. When you simplify it, you get 5=b. I really hope this is correct, I apologize if it isn't! I hope this helps! :)
