Quotient of a number x and 45?
is equal to x45
Answer:
the solution set is r>7
step by step:
Subtract 3 from both sides
3−3r−3<−2r−4−3
Simplify
−3r<−2r−7
Add 2r to both sides
−3r+2r<−2r−7+2r
Simplify
−r<−7
Multiply both sides by −1 (reverse the inequality)
(−r)(−1)>(−7)(−1)
Simplify
r>7
Answer:
1 29/63
Step-by-step explanation:
To add fractions, find the LCD and then combine.
Answer:
a² + b² = c · (e + d) = c × c = c²
a² + b² = c²
Please see attachment
Step-by-step explanation:
Statement, Reason
ΔADC ~ ΔACB, Given
AC/AD = BA/AC, The ratio of corresponding sides of similar triangles
b/e = c/b
b² = c·e
ΔBDC ~ ΔBCA, Given
BC/BA = BD/BC, The ratio of corresponding sides of similar triangles
a/c = d/a
a² = c·d
a² + b² = c·e + c·d
a² + b² = c · (e + d)
e + d = c, Addition of segment
a² + b² = c × c = c²
Therefore, a² + b² = c²
Answer:
B.
Step-by-step explanation:
there is not much to explain.
a strong correlation means there is a direct connection.
so, a change in a causes immediately a change in b.
and positive means that the changes go in the same sign direction. increase => increase. decrease => decrease.
