Answer:
(B) all numbers less than 7
Step-by-step explanation:
Given the inequality:
x<7
It means that:
- x cannot be equal to 7
- x cannot be greater than 7
Therefore, x<7 consists <u>of all numbers less than 7.</u>
Answer:
Step-by-step explanation:
Given

Determine the missing angles
Since AB = AD, then:
--- Base angles of an isosceles triangle
Hence:
--- angles in a triangle
Collect Like Terms
--- angle on a straight line
Since ABC is isosceles, then:
--- base angle of isosceles

Answer:
x = 12
Step-by-step explanation:
The triangles are similar so we can use ratios
4x+12 32
------- = ------------
15 8
Using cross products
(4x+12) *8 = 15 * 32
(4x+12) *8 = 480
Divide each side by 8
(4x+12) *8/8 = 480/8
4x+12 = 60
Subtract 12 from each side
4x+12 -12 = 60-12
4x = 48
Divide by 4
4x/4 = 48/4
x = 12
