AnnZ [28]

Answer with explanation:

To find the common multiple of 45 and 95,we will find HCF of 45 and 95.

45=3 × 3× 5

95=5 × 19

⇒H CF(45,95)

=3 × 3×5×19

=855

→Common multiple of 45 and 95 =855

→There are infinite number of multiple of 855 which are 855, 1710, 2565,.....

You have not written between which two numbers.So, you should write multiple of 855 such that it is smaller than the greater number.

For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. Write an equation for the cost, C, after h hours of babysitt
Svet_ta [14]

Answer:

Step-by-step explanation:

Let h represent the number of hours of babysitting.

C represents the total cost of babysitting for h hours.

For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. Therefore, the equation would be

C = 5h + 3

Comparing the equation with the slope intercept form, y = mx + c,

The slope = 5

The y intercept = 3

If she babysits for 5 hours, the cost would bee

C = 5 × 5 + 3

C = $28

HELP PLEASE 30 POINTS<br><br> 2x-3y=8 x-3y=8. solve with linear composition
Scrat [10]

Answer:

(0,-8/3)

Step-by-step explanation:

2x-3y=8

x-3y=8

Multiply the second equation by -1 and add together

2x-3y=8

-x+3y=-8

---------------------

x +0y =0

x=0

Now we can find y

2x -3y =8

0-3y =8

Divide by -3

-3y/-3 = 8/-3

y = -8/3

(0,-8/3)
