What’s the answer to 1.9m + 14 = 2m?

joja [24]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{m = 140}}}}}$

Step-by-step explanation:

$\sf{1.9m + 14 = 2m}$

Move 2m to right hand side and change it's sign

Similarly, move 14 to left hand side and change it's sign

$\dashrightarrow{ \sf{1.9m - 2m = - 14}}$

Collect like terms

$\dashrightarrow{ \sf{ - 0.1m = - 14}}$

Divide both sides by -0.1

$\dashrightarrow{ \sf{ \frac{ - 0.1m} { - 0.1} = \frac{ - 14}{ - 0.1}}}$

Calculate

$\dashrightarrow{ \sf{m = 140}}$

Hope I helped!

$( - \frac{3}{4} )( \frac{7}{8} )$

$= \frac{ - 3}{4} \times \frac{7}{8}$

$= \frac{ - 21}{32}$

_______________________________________

$( \frac{2}{3} )( - 4)(9)$

$= \frac{2}{3} \times - 4 \times 9$

$= \frac{ - 72}{3}$

$= - 24$

_______________________________________

$( \frac{5}{16} )( - 2)( - 4)( - \frac{4}{5} )$

$= \frac{5}{16} \times - 2 \times - 4 \times \frac{ - 4}{5}$

$= \frac{ - 160}{80}$

$= \frac{ - 16}{8}$

$= - 2$

_______________________________________

$(2 \frac{3}{5} )( \frac{7}{9} )$

$= \frac{13}{5} \times \frac{7}{9}$

$= \frac{91}{45}$

A pet store was selling 4 lizards for $47.88. If they ended up selling 6 lizards, how much would they have earned?

fgiga [73]

Answer:

Step-by-step explanation:

Step one- Find out how much it costs for one Lizard In this case, for four lizards it costs $47.88. To find the price for one lizard you divide 47.88 by four

$47.88/4Lizards=$11.97 per lizard.

Step two- Now that we have the price for one lizard, your question asks you how much for 6 lizards. We need to find that cost. To do so you multiply $11.97 by 6 for the lizards.

Your answer is $71.82

Hope This Helped :)
