Answer:
8x
Step-by-step explanation:
The constants are the numbers that are NOT
attached to anything. In the expression, 3x + 2,
(2) is a constant because it is not attached to
anything. The (3) is not a constant because it
is attached to x, and it is actually a coefficient.
Answer:
7) C) PQR ≈ TSR
8) B) 3
9) D) 102 ft
10) D) 21
11) C) 45
Step-by-step explanation:
7) C) PQR ≈ TSR
8) 2 * 6 = 12
so 4x = 12
x = 3
9)
24/20 = x/85
x = 24 * 85 / 20
x = 202 ft
10)
QT/35 = 24/40
QT/35 = 3/5
QT = 35 * 3 / 5
QT = 21
11)
ΔKLM ≈ΔXYZ
9/4 = 2.25
So
XY = 9 ---> given
YZ = 7 * 2.25 = 15.75
XZ = 9 * 2.25 = 20.25
Perimeter ΔXYZ = 9 + 15.75 + 20.25 = 45
Step-by-step explanation:
It is required to find the expressions that are equivalent to 4-x. We can also write it as :
Option (b) : (4-x) = 4+(-x)
Option (c) : (4-x) = -x+4
Hence, the correct options are (B) and (C).
Answer:

Step-by-step explanation:
All the angles in a triangle add up to 
Every right angle triangle has a right angle in it which is 
So to find the remaining angle, you do
-
-
= 
Answer:
$99/$115 x 100% = 86.086% of the original price
So 100% - 86.086
= 13.9 = 14%
Or you could just do (115 - 99) x 100 which gets the same answer.
