Four glasses of milk and 3 snack bars have a total of 82 carbohydrates (carbs), and 2 glasses of milk and 4 snack bars have a to

vredina [299]

Answer:

milk: 10 carbs
snack bar: 14 carbs

Step-by-step explanation:

Let m and s represent the carbs in the milk and snack bar, respectively. The given relations are ...

4m +3s = 82

2m +4s = 76

Subtracting the first equation from twice the second gives ...

2(2m +4s) -(4m +3s) = 2(76) -(82)

5s = 70 . . . . . . . simplify

s = 14 . . . . . . . divide by 5

We substitute this into the second equation to find m.

2m +4(14) = 76

m +28 = 38 . . . . divide by 2

m = 10 . . . . . . subtract 28

There are 10 carbs in a glass of milk; 14 carbs in a snack bar.

X =<br><br> a) 43<br> b) 58<br> c) 71

Eduardwww [97]

$28 \textdegree = \frac{1}{2} ( 114 \textdegree - \angle x)$

$28 \textdegree = 57 \textdegree - \frac{1}{2} \angle x$

$\frac{1}{2} \angle x = 57 \textdegree - 28 \textdegree$

$\frac{1}{2} \angle x = 29 \textdegree$

$\angle x = 29 \textdegree \times 2$

$\angle x = 58 \textdegree$
