Answer:

- 7m + 8/5

Step-by-step explanation:

- 2/5 ( 15m - 4 ) - m

 Multiply - 2/5 with 15m & - 4.

 ( - 2/5 x 15m ) - ( - 2/5 x 4 ) - m

= ( - 2 x 15m )/5 - ( - 2 x 4 )/5 - m

= - 30m/5 - ( - 8 )/5 - m

= - 6m + 8/5 - m

= - 6m - m + 8/5

= - 7m + 8/5

Answer:   \boldsymbol{-7}m + \boldsymbol{\frac{8}{5}}

Work Shown:

-\frac{2}{5}(15m-4)-m\\\\-\frac{2}{5}(15m)-\frac{2}{5}(-4)-m\\\\-6m+\frac{8}{5}-m\\\\\boldsymbol{-7}m + \boldsymbol{\frac{8}{5}}

Therefore -7 goes in the first box, and \boldsymbol{\frac{8}{5}} goes in the second box.

What is the value of x?<br> 160°<br> x =<br> 519
forsale [732]

Answer:

x = 58

Step-by-step explanation:

Angle Formed by Two Secants = 1/2(difference of Intercepted Arcs)

51 =1/2 (160-x)

Multiply each side by 2

102 = 160-x

Subtract 160 from each side

102-160 = -x

-58 = -x

Multiply by -1

58 =x

Answer/Step-by-step explanation:

<em>Formula:</em>

<em>C = 2πr</em>

<em>Note: π = 3.14(About)</em>

<em>-------------------------------------------------------------------------------------------------------------</em>

<em>[3] It given that the diameter is 16 ft.</em>

Diameter - a straight line passing from side to side through the center of a body or figure

Radius - Half of Diameter

C = 3.14(16)

= 50.24 ft

<em>-------------------------------------------------------------------------------------------------------------</em>

<em>[4] It given that the radius  is 7.5 in</em>

<em>Radius - a line segment extending from the center of a circle or sphere to the circumference or bounding surface.</em>

<em>C = 3.14(15)</em>

<em>= 47.1 in</em>

<em>-------------------------------------------------------------------------------------------------------------</em>

<em>[5] It given that the radius is 42 m </em>

<em>C = 3.14(84)</em>

<em>= 263.76 m</em>

<em>-------------------------------------------------------------------------------------------------------------</em>

<u><em>As Noted : π is approximately 3.14. Thus the answers are approximately</em></u>

How many solutions does the system have?<br> 3x + y = 8<br> 2 + 2y = 8
REY [17]

Answer:

x=2,y=2

Step-by-step explanation:

This question is a simultaneous equation

So let's solve

3x+y=8...(1)

2x+2y=8....(2)

Multiply (1) by 2

6x+2y=16...(3)

Substrate (2) From (3)

4x=8

Let's make x the subject of formula by dividing both sides by 4

x=2

So let's substitute the value of x into (1)

3x+y=8

3(2)+y=8

6+y=8

y=8-6

y=2

Therefore x is 2,y is 2
