2:30
+ 30
=

+ 25
= 3:55

4:45 - 3:55
= 50 minutes

Stephen evaluated (6.34 times 10 Superscript negative 7 Baseline) (4.5 times 10 Superscript 3 Baseline). His work is shown below

Zarrin [17]

Steps 4 and 5 describe the errors Stephen made.

Stephen evaluated $(6.34\times 10^{-7})(4.5\times 10^3)$ .

His work is shown below.

<h3> Which two statements describe the errors Stephen made?</h3>

Step 1 - $(6.34\times 10^{-7})(4.5\times 10^3)$

Step 2 - $=(6.34\times 4.5)(10^{-7} \times 10^3)$

Step 3 - $=(28.53)(10^{-4})$

Step 4 - $20.53\times 10^4$

Error is the step as 4 sign is negative.

So correct step is $=(28.53)(10^{-4})$

Step 5 - $=(28.53)(10^{-4})$

Error is the step as there are 4 in place of 3.

So correct step is $=(28.53)(10^{-4})$

Steps 4 and 5 describe the errors Stephen made.

Solve and check 2/3y =6 A.1/9 B.1/4 C.9 D.4

kotegsom [21]

$\frac{2}{3}y=6\ \ \ \ |divide\ both\ sides\ by\ \frac{2}{3}\ /multiply\ by\ \frac{3}{2}/\\\\y=6\cdot\frac{3}{2}\\\\y=\frac{6}{1}\cdot\frac{3}{2}\\\\y=\frac{\not6^3\cdot3}{1\cdot\not2_1}\\\\y=\frac{3\cdot3}{1\cdot1}\\\\y=\frac{9}{1}\\\\\boxed{y=9}\leftarrow answer\ \boxed{C}$

$check:\\\\/put\ the\ value\ of\ y=9\ to\ the\ equation\ \frac{2}{3}y=6/\\\\\frac{2}{3}\cdot9=6\\\\\frac{2}{3}\cdot\frac{9}{1}=6\\\\\frac{2}{\not3_1}\cdot\frac{\not9^3}{1}=6\\\\\frac{2}{1}\cdot\frac{3}{1}=6\\\\2\cdot3=6\\\\\boxed{6=6}\leftarrow TRUE$
