Mark bought 12 boxes of paper clips and 10 packages of index cards for a
Nata [24]

Answer:

paper clips = $1.85

index cards = $3.95

Step-by-step explanation:

Mark

12 paper clips = x

10 index cards = y

$61.70 total

Janice

15 paper clips = x

7 index cards = y

$55.40 total

12x + 10y = 61.70

15x + 7y   = 55.40

*** you want to cancel out one of the letters

(12x + 10y = 61.70) * -7

(15x + 7y   = 55.40) * 10

-84x -70y = -431.9

150x + 70y = 554.0

150x + 70y = 554.0

-84x -70y = -431.9

66x + 0 = 122.1

66x = 122.1

x = 122.1 ÷ 66

x = 1.85

plug it back in

15(1.85) + 7y   = 55.40

27.75 + 7y   = 55.40

7y   = 55.40 - 27.75

7y = 27.65

y = 27.65 ÷ 7

y = 3.95

Naddika [18.5K]

Answer : 110 degree

To find angle 1 , we apply outside angle theorem  Lets name each point  Measurement of arc EF=280 degrees  

Measurement of arc GH = 60

Angle D = angle 1

Please refer to the theorem attached below  

angle D = \frac{arc(EF)-arc(GH)}{2}

Now we plug in the values

angle 1 = \frac{280-60}{2}

angle 1 = 110

Measurement of angle 1 = 110 degrees
