Help on question 11. A) please

Mathematics
1 answer:
lana [24]4 years ago
7 0
They didn't follow PEMDAS. according to pemdas, exponents come first (since there are no parentheses here), so they were right to simplify 4^2 to 16. However, multiplication and division come before addition and subtraction, which means they should have multiplied 5 by 3 and then subtracted the product from 16.

So, the work really should have shown 16-15=1.

Answer:

X - 7 = 13 - x help asap plz
bekas [8.4K]

Answer:

x = 10

Step-by-step explanation:

x - 7 = 13 - x

Step 1 : Collect like terms and simplify

x + x = 13 + 7 \\ 2x = 20

Step 2 : Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{20}{2}

Step 3 : Simplify by cross cancellation of common term : 2

x = 10

slamgirl [31]

Answer: <em>Multiplying these factors gives the approximate volume of the original body</em>

Step-by-step explanation:

<em>The given convex body can be approximated by a sequence of nested bodies, eventually reaching one of known volume (a hypersphere), with this approach used to estimate the factor by which the volume changes at each step of this sequence.</em>
