Answer:

m = 84/31

Step 1: Simplify

\frac{3(m-1)-4}{5} =\frac{8-(2m+1)}{7}

\frac{3(m-1)-4}{5}=\frac{8-(2m+1)}{7}

Step 2: Cross multiply

7*\frac{3(m-1)-4}{5}=\frac{8-(2m+1)}{7}*5

21m-49=-10+35

Step 3: Add 10m to both sides

21m-49+10m=-10m+35+10m

31m-49=35

Step 4: Add 49 to both sides

31m-49+49=35+49

31m=84

Step 5: Divide both sides by 31

\frac{31m}{31} =\frac{84}{31}

m=\frac{84}{31}

Komok [63]

Answer:

Cost, C = $28410.72

Step-by-step explanation:

We have, a concrete pillar has the shape of a cylinder.

Diameter of pillar is 8 m and ts height is 9 m

If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,

A=2\pi rh+2\pi r^2\\\\A=2\times 3.14\times 4\times 9+2\times 3.14\times 4^2\\\\A=326.56\ m^2

The cost of pillar at the rate of $87 per cubic meter will be :

C=326.56\times 87\\\\C=\$28410.72

2x - 5= 5x + 7 linear equations
Bezzdna [24]

Answer:

-4 =x

Step-by-step explanation:

2x - 5= 5x + 7

Subtract 2x from each side

2x-2x - 5= 5x-2x + 7

-5 = 3x+7

Subtract 7 from each side

-5-7 = 3x+7-7

-12 = 3x

Divide by 3

-12/3 = 3x/3

-4 =x
