Tems11 [23]

Answer:

78 emails

Step-by-step explanation:

Given

Represent sent emails with x and received with y.

So, we have:

x + y = 114 -- First statement

y = 6 + 2x -- Second statement

Required

Determine the number of emails received (y)

Make x the subject in x + y = 114

x = 114 - y

Substitute 114 - y for x in y = 6 + 2x

y = 6 + 2(114 - y)

Open bracket

y = 6 + 228 - 2y

Collect Like Terms

2y+y = 6 + 228

3y = 234

Divide by 3

y = 234/3

y = 78

Answer:

C. Cos(28) = \frac{15}{17}

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

Cos(\theta) = \frac{Adjacent}{Hypotenuse}

Reference angle = 28°

Adjacent = 15

Hypotenuse = 17

Plug in the values

Cos(28) = \frac{15}{17}
