Answer these for brainliest and 20 points

1: y = 5, x = 2,    2: x = 3, y = 1,     3: y = 4, x = -1,       4: x = -1, y = -8/5,      5: y = 4, x = -14

Step-by-step explanation:

If you look closely, you can cancel some terms, and then you can substitute

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
