Answer:

<em>There would be 20 ounces of almonds in the bag</em>

Step-by-step explanation:

<u>System of Equations</u>

To solve the problem, we'll set up these two variables:

x = ounces of almonds

y = ounces of raisins

The ratio of almonds to raisins in the trail mix is 5:7, thus:

\displaystyle \frac{x}{y}=\frac{5}{7}

Cross-multiplying:

7x=5y         [1]

A 3-pound bag of this trail mix contains 3*16=48 ounces that include almonds and raisins, thus:

x + y = 48      [2]

Multiplying [2] by 5:

5x + 5y = 240

Substituting from [1]:

5x + 7x = 240

12x = 240

x = 240/12

x = 20

There would be 20 ounces of almonds in the bag

If mBGC = 16x - 4 and mCGD = 2x + 13, find the value of x so that BGD is a right angle​
Lelu [443]

Hi there! :)

Answer:

\huge\boxed{x = 4.5}

m∠BGC = 16x - 4

m∠CGD = 2x + 13

m∠BGC + m∠CGD sums up to 90°, therefore:

(16x - 4) + (2x + 13) = 90

Combine like terms and simplify:

16x + 2x - 4 + 13 = 90

18x - 4 + 13 = 90

18x + 9 = 90

18x = 81

18x/18 = 81/8

x = 4.5

Answer:

x=9

<A=23

<B= 69

Step-by-step explanation:

1. 2x+5+3(2x+5)=92     2. 2x+5+6x+15=92     3. 8x+20=92     4. 8x=72     5. x=9

<A= 2(9)+5=18+5=23

<B= 3(2(9)+5)=3(23)=69
