Answer:

(90,60)

Step-by-step explanation:

if you look closely through the linear graph, the line crosses through (90,60) and not the other given pairs.

proportional relationships are plots that also match in the same graphing format (keep in mind when you have trouble next time)

Whats the answer for 12 (2w-3)=6w

puteri [66]

12(2w-3)=6w
Distribute
24w-36=6w
Rearrange
18w=36
Divide both sides by 18
W=36/18
Final answer:
W=2

A machine with velocity ratio of 5 is used to raise a load with an effort of 500N . If the machine is 80% efficient , determine

Yanka [14]

Answer:

Solutions given:

Velocity ratio V.R =5

effort =500N

efficiency =80%

magnitude of load=?

mechanical advantage [M.A ]

we have

efficiency =M.A/V.R*100%

80=M.A./5*100

80/100*5=M.A

M.A.=4

again

we have

M.A =load/effort

4=load/500

load=500*4

load=2000N

<h3><u>the magnitude of the load is 2000N</u>.</h3>

Finish solving the system of equations –9.5x – 2.5y = –4.3 and 7x + 2.5y = 0.8 using the linear combination method.

trasher [3.6K]

Answer:

The value of x is 1.4 and y is -3.6

Step-by-step explanation:

The steps are :

$- 9.5x - 2.5y = - 4.3 - - - (1)$

$7x + 2.5y = 0.8 - - - (2)$

$(1) + (2)$

$- 9.5x + 7x - 2.5y + 2.5y = - 4.3 + 0.8$

$- 2.5x = - 3.5$

$x = \frac{7}{5} \: or \: 1.4$

$substitute \: x = 1.4 \: into \: (2)$

$7(1.4) + 2.5y = 0.8$

$9.8 + 2.5y = 0.8$

$2.5y = - 9$

$y = - \frac{18}{5} \: or \: - 3.6$

Use the interactive number line to find the difference. 4.7 - 2.3 = 4.7 + (-2.3) =

FromTheMoon [43]

Answer:

Arrow from 0 to 4.7 and from 4.7 to 2.4

Step-by-step explanation:

4.7 is also 0+4.7

arrow from 0 to 4.7.

-2.3 from 4.7 is 4.7-2.3=2.4

arrow from 4.7 to 2.4.
