Answer:

Almonds = 5 and 3/5 pounds Pecans = 8 and 2/5 pounds 8+5=13 3/5+2/5= 5/5(=1) 13+1 =14

Step-by-step explanation:

14 pounds at $4.80 =$ 67.20

A=almonds P = pecans

a+p = 14 p=(14-a)

5.25A + 4.50(14-A) = 67.20

5.25A + 63 - 4.5A= 67.20

0.75A = 4.20

A=5.6 P= 14-5.6 = 8.4

Almonds 5.6*5.25 = 29.4

Pecans 8.4* 4.50= 37.8

29.4 + 37.8 = 67.20

Select the expression that has a value of 96.45

leonid [27]

Given:

Number is 96.45.

To find:

The expression that has a value of 96.45.

Solution:

In option a,

$0.9645\times 10^2=0.9645\times 100$

$0.9645\times 10^2=96.45$

In option b,

$9.645\div 10^1=\dfrac{9.645}{10}$

$9.645\div 10^1=0.9645\neq 96.45$

In option c,

$964.5\times 10^3=964.5\times 1000$

$964.5\times 10^3=964500\neq 96.45$

In option d,

$9645\div 10^3=\dfrac{9645}{1000}$

$9645\div 10^3=9.645\neq 96.45$

Therefore, the correct option is a.
