Mathematics

Answer:

s  = -70 in the given expression.

Step-by-step explanation:

Here, the given expression is:

\frac{s}{3} - \frac{7}{6} + \frac{2s}{5} = \frac{3s}{4}

Now, to find the value of s, we need to simplify the given expression:

We get:

\frac{s}{3} - \frac{7}{6} + \frac{2s}{5} = \frac{3s}{4}\\\implies \frac{s}{3}  + \frac{2s}{5} -  \frac{3s}{4}  = \frac{7}{6}\\\implies\frac{20(s) + 12(2s) - 15(3s)}{60}    = \frac{7}{6}\\\implies \frac{20 s  + 24 s - 45 s}{60}   = \frac{7}{6}\\\implies \frac{-s}{60} = \frac{7}{6}\\\implies s = \frac{7}{6} \times (-60)  = - 70\\\implies s  = (- 70)

Hence, s  = -70 in the given above expression.

Quadrilateral ABCD is inscribed in circle 0 What is m<A
valentinak56 [21]
We know that
 A quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary. ( Inscribed Quadrilateral Theorem)
so
m∠B+m∠D=180°
2x+(3x-5)=180
5x=180+5
5x=185
x=185/5
x=37°

m∠A=x+5-----> 37+5------> 42°

the answer is
m∠A is 42°

Sams building a suspension bridge for the playground at the elementary school I needed some chain-link and some rope he bought a
a_sh-v [17]

Answer:

Amount of material for chain link = 30 feet

Amount of material for rope = 50 feet

Step-by-step explanation:

Let the amount of chain link = X

The amount of rope be represented by Y

He bought a total of 80 feet of materials

Hence we have:

X + Y = 80 ....... Equation 1

Y = 80 - X

The chain-link cost two dollars per foot and the rope cost 1.50 per foot he spent a total of $135

X × $2 + Y × $1.50 = $135

2X + 1.5Y = 135 ......Equation 2

Substitute 80 - X for Y in Equation 2

2X + 1.5(80 - X) = 135

2X + 120 - 1.5X = 135

Collect like terms

2X - 1.5X = 135 - 120

0.5X = 15

X = 15/0.5

X = 30 feet

Substitute 30 feet for X in Equation 1

X + Y = 80 ....... Equation 1

30 + Y = 80

Y = 80 - 30

Y = 50 feet

Hence the amount of material he used for the chain link = 30 feet and the amount of material he used for the rope was = 50 feet

(3x - 9) + x + (x + 28) = 184.
julia-pushkina [17]

Answer:

33

Step-by-step explanation:

rearrange and combine like terms

(3x - 9) + x + (x + 28) = 184

3x - 9 + x + x + 28 = 184

3x + x + x + 28 - 9 = 184

3x + x + x = 184 + 9 - 28

5x = 165

x = 33

Make a the subject of the formula:<br> 10a + 9b = 3c
Anuta_ua [19.1K]

Answer:

a = \frac{3c - 9b }{10}

Step-by-step explanation:

10a + 9b = 3c

Subtract 9b to isolate the variable a.

10a = 3c - 9b

Now we need a singular a, so divide equation by 10.

a = \frac{3c - 9b }{10}

So that's how you do it.
