Answer:
Step-by-step explanation:
(27)
We can apply ratios to solve for the problem.
Let x be the missing value.
Cross multiply.
152 × x = 532 × 4
152x = 2128
Divide both sides by 152.
x = 14
(29)
We can apply ratios to solve for the problem.
Let x be the missing value.
Cross multiply.
1 × x = 6 1/4 × 2/3
x = 6 1/4 × 2/3
Convert mixed fraction to improper fraction.
x = 25/4 × 2/3
x = 50/12
Simplify.
x = 25/6 or 4 1/6

Answer:
-361
Step-by-step explanation:
Your calculator can tell you the result. It is -361.
Start with the inner parentheses and work outward. Do multiplication and division in the order shown, left to right, before addition or subtraction.
-3[2/6+8{-9/3(8-5*3)-6}]
= -3[2/6+8{-9/3(8-15)-6}]
= -3[2/6+8{-9/3(-7)-6}]
= -3[2/6+8{-3(-7)-6}]
= -3[2/6+8{21-6}]
= -3[2/6+8{15}]
= -3[1/3+8{15}]
= -3[1/3+120]
= -3[361/3]
= -361
Answer:
D(4,-3)
Step-by-step explanation:
Given three of the vertices of the square: A(4, -7), B(8, -7),C(8, -3)
Let the coordinate of the fourth vertex be D(x,y).
We know that diagonals of a square are perpendicular bisector. So, the midpoint of both diagonals is the same.
The diagonals are BD and AC
Midpoint of BD = Midpoint of AC
The coordinates of the fourth vertex is D(4,-3)
