Answer:

R = 4

s = -3

Step-by-step explanation:

r + 4s = -8

3r + 2s = 6

there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:

-6r - 4s = -12 and added it to the first equation

+ <u> 1r + 4s = -8</u>

-5r = -20

r = 4

plug in to find 's': 4 + 4s = -8

4s = -12

s = -3

g A program executes a mix of different instruction types. 25% of the instructions require two clock cycles to execute, 20% requ

Tomtit [17]

Answer:

1.8 cycles

Step-by-step explanation:

The average number of clock cycles per instruction is given by the sum of the product of each possible number of cycles by its likelihood.

1 cycle: 50%

2 cycles : 25%

3 cycles : 20%

4 cycles : 5%

$Avg = 0.5*1+0.25*2+0.20*3+0.05*4\\Avg= 1.8\ cycles$

The average number of clock cycles per instruction is 1.8.

Twice the sum of the number and 10 is 60 what is the number?

n200080 [17]

Let the number be n

$\\ \sf\longmapsto 2(n+10)=60$

$\\ \sf\longmapsto n+10=60/2$

$\\ \sf\longmapsto n+10=30$

$\\ \sf\longmapsto n=30-10$

$\\ \sf\longmapsto n=20$

A music store 3,550 CDs. Each CD rack holds 15 CDs. How many racks does the store need to use to hold all the CDs?

pentagon [3]

3550 cds divided by 15 cds/ rack = 236.66667

Meaning that there will be 236 full racks and the last rack will only have 10 cds
