Answer:

see explanation

Step-by-step explanation:

a.

3(x - 4) = 12 ( divide both sides by the multiplier 3 )

x - 4 = 4 ( add 4 to both sides )

x = 8

b.

\frac{1}{4}(a - 16) = 16 ( multiply both sides by 4 )

a - 16 = 64 ( add 16 to both sides )

a = 80

c.

2y - 15 = - 1 ( add 15 to both sides )

2y = 14 ( divide both sides by 2 )

y = 7

d.

\frac{2c-6}{2} = 9 ( multiply both sides by 2 )

2c - 6 = 18 ( add 6 to both sides )

2c = 24 ( divide both sides by 2 )

c = 12

Write the decomposition that helps you, and then round to the given place value. Draw number lines to explain your thinking. Cir

Further explanation

There are general rules used in rounding numbers

1. Determine the rounded digit

2. Pay attention to the digits afterward (right). If the digit shows the numbers 0, 1, 2, 3 or 4, then the digit to be rounded is fixed, and the digit on the right is 0 all

3. If the digit on the right shows the numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added to one, and the digit on the right side is made all 0

In rounding the nearest hundreds number, then we see the digit in the number tens (right of the digit hundreds), if it is worth 0, 1, 2, 3 or 4, then it remains, but if it shows numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added one, and the right-hand side is 0

Calculated from the decimal point, the place on the right represents tents, hundredths, thousandths, etc.

a.  32.697

Decomposition

ten : 3

one : 2

tenth : 6

hundredth : 9

thousandths : 7

For the tenth number is 6, the value on the right is 9 then rounded become 32.7

For the hundredth number is 9, the value on the right is 7 then rounded become 32.70

for the one number is 2 , the value on the right is 6 then rounded become 33

b. 141.999

Decomposition

hundred : 1

ten : 4

one : 1

tenth : 9

hundredth : 9

thousandths : 9

a. For the tenth number is 9, the value on the right is 9 then rounded become 142.0

For the hundredth number is 9, the value on the right is 9 then rounded become 142.00

For the ten number is 4, the value on the right is 1 then rounded become

14

For the ten number is 1, the value on the right is 4 then rounded become

142

greg wants to divide a 2 and 1/2 pound block of cheese into four equal pieces. How much will each piece weigh?
Alex73 [517]

let's firstly convert the mixed fraction to improper fraction and then divide.

\bf \stackrel{mixed}{2\frac{1}{2}}\implies \cfrac{2\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{5}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{5}{2}\div 4\implies \cfrac{5}{2}\div \cfrac{4}{1}\implies \cfrac{5}{2}\cdot \cfrac{1}{4}\implies \cfrac{5}{8}
