Sheera followed these steps to subtract 406 - 128. Step Five is missing: Step One: 128 + 2 = 130
Step Two: 130 + 70 = 200
Step Three: 200 + 200 = 400
Step Four: 400 + 6 = 406
Step Five:
Which of the following is the correct next step to solve the problem 406 - 128 = ?
O Add 128 + 130 + 200 + 400
Add 2 + 70 + 200 + 6
Add 400 + 6
Subtract 278 - 128

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

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  

x

=240
