To eliminate x, you can multiply the second equation by 2. This will make -2x into -4x, so that 4x and 4x will be able to cancel out leaving you to solve for y.

To eliminate y, you can multiply the second equation by 3. This will make 3y into 9y, so that -9y and 9y will be able to cancel out leaving you to solve for x.
Hope this helped.

Drag the choices into the boxes to explain how all real numbers have a decimal expansion.
KATRIN_1 [288]

The decimal forms of some real numbers, like( 3/16), terminate, while the decimal forms of other real numbers, like(4 2/11 ), do not terminate, but have a repeating pattern. Still, other real numbers, like(5 squared ), have decimal forms that neither terminate nor repeat.

Step-by-step explanation:

1. The decimal forms of some real numbers, like( ), terminate

A number is terminating if it has decimal with finite number

So, \frac{3}{16}= 0.1875 as decimal stops after 4 digits so it is terminating.

2.  the decimal forms of other real numbers, like( ), do not terminate, but have a repeating pattern.

A number that do not terminate, but have a repeating pattern.

So, 4 \frac{2}{11} =\frac{44}{11}=4.1818181

3. have decimal forms that neither terminate nor repeat

5^2 = 25 it neither terminates nor repeat

So, answers will be:

The decimal forms of some real numbers, like( 3/16), terminate, while the decimal forms of other real numbers, like(4 2/11 ), do not terminate, but have a repeating pattern. Still, other real numbers, like(5 squared ), have decimal forms that neither terminate nor repeat.

A customer went to a garden shop and bought some potting soil for $12.50 and 5 shrubs. The total bill was $62.50. Write and solv
lesya692 [45]

Answer:  Equation:  5x = 62.50 - 12.50    or   x = \frac{62.50-12.50}{5}  

x is the cost of each shrub  x = $10

Step-by-step explanation:  Total bill = $62.50.

Subtract the cost of potting soil for $12.50 to find the cost of just the shrubs.   5x  equals that amount

5x = 62.50 - 12.50

5x = 50   divide both sides by 5  

5x/5 = 50/5

x = 10

If a bank has total deposits of $7,200 and reserves of $1,600: instructions: round to the nearest whole number. (a) what is its
Serjik [45]
A.) The current reserve ratio is given by the fraction of the bank's total deposits held in reserves.
Given that the bank's total deposits is $7,200 and the reserves is $1,600, the current reserve ratio is given by:

\frac{1,600}{7,200} \times100\%=22\%.


b.) The loan portfolio is given by (total deposit - reserves) / total deposits

Thus, the loan portfolio of the given bank is given by:

\frac{7,200-1,600}{7,200} \times100\%= \frac{5,600}{7,200} \times100\% \\  \\ =78\%
