Answer:

(3,11)

Step-by-step explanation:

Turn both equations into linear equations:

y=2x+5

An ant weighs 2 x 10^-3 grams, and a lion weighs 1 x 10^5. The lion's weight is 5 x 10^x times greater than the ant's weight. Wh

julsineya [31]

Answer:

x=7

Step-by-step explanation:

Information provided

Weight of ant= $2*10^{-3} grams$

Weight of lion= $1*10^{5}$ but units are not provided, assuming this unit is also grams

How many times lion's weight exceed an ant

$\frac {1*10^{5}}{2*10^{-3}}=50000000$

= $5*10^{7}$

Therefore, the value of x=7 if the unit for weight of lion is assumed to be same as unit for weight of an ant
