Answer:
y = 3/2x by making use of angle relationships in triangles
Step-by-step explanation:
Here's one way to solve it.
∠ADE is an external angle to ΔBDE. As such, its measure will be the sum of the measures of the remote interior angles, ∠DBE and ∠DEB:
∠ADE = 2x° +y°
__
If we call the intersection point of AC and DE point G, then ∠AGE is an exterior angle to ΔADG. As such, its measure is the sum of the remote interior angles:
∠AGE = ∠GAD +∠GDA
3y° = x° +(2x° +y°)
2y = 3x . . . . . . . . . . subtract y°, collect terms, divide by °
y = (3/2)x . . . . . . . . divide by 2
Answer:
1/8 and 7/8
Step-by-step explanation:
First convert 1/2 to 4/8.
Then, subtract and add 3/8
(4/8 - 3/8 = 1/8, 4/8 + 3/8 = 7/8)
Answer:
Step-by-step explanation:
Isolate the variable to find the solution set.
The store has a stock of <span>12 AA batteries and 15 9V batteries. So, these are the limits of the batteries that Mrs. Gibbs can only buy. She already bought 7 pieces of AA batteries. Then, she needs to buy only at least 20 batteries. Therefore, she should buy all of the stock of AA batteries which is 12 pieces.</span>
