Answer:
Step-by-step explanation:
: Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).
City hall to post office = 6 1/2 miles = represented by f
city hall to library site = 1 1/4 miles = represented by d
library site to post office = unknown. = represented by e
City hall to library site PLUS library site to post office IS EQUAL to city hall to post office
d + e = f
1 1/4 + e = 6 1/2
find e.
e = 6 1/2 - 1 1/4
e = 13/2 - 5/4
e = (13*2)/(2*2) - 5/4
e= 26/4 - 5/4
e = (26-5)/4
e = 21/4
e = 5 1/4 distance from library site to post office.
To check:
d + e = f
1 1/4 + e = 6 1/2
1 1/4 + 5 1/4 = 6 1/2
6 2/4 = 6 1/2
6 1/2 = 6 1/2
X - y = 7
y = x - 7
Parallel = same slope
The slope is 1
Y = x + b
0 = 1 + b, b = -1
Equation: y = x - 1
Answer:
(x - y) (x+y -1)
Step-by-step explanation:
<u>See steps of factorization:</u>
- x² - y² - x + y =
- (x² - y²) - (x - y) =
- (x - y) (x + y) - (x- y) =
- (x - y) (x+y -1)
Answer:
w=−7
Step-by-step explanation:
34+21=−11(w+2)
55=−11(w+2)
-55/11 =w+2
−5=w+2
−5−2=w
−7=w
