The Idol's Eye diamond weighs 79.2 carats. The Blue Hope diamond weighs 33.68 carats less than the Idol's Eye. What is the weight of the Blue Hope diamond?
The answer would be 18 because you would subtract 45 from 27.
45 - k = 27
45 - 27 = k 45 - 27 = 18
Answer: k = 18
Substitution method of y=x+5 and 5x+y=3
Answers
To solve by substitution, you need to fill in the value for either x or y. Since y = x + 5, you already have the y value. It's x + 5. Now you need to find x before you can go any further. So let's take 5x + y = 3 and fill x + 5 in for y. 5x + y = 5 5x + x + 5 = 3 Now solve for x. 5x + x + 5 = 3 6x + 5 = 3 6x = 3 - 5 6x = -2 x = -2/6 or -0.33 Now solve x + 5 for y. y = x + 5 y = -0.33 + 5 y = 4.67 So x = -0.33 and y = 4.67
Solve for the first variable in one of the equations,then substitute the result into the other equation. (-1/3,14/3)
What's the answer for number 4? And did I graph it right?
Answers
Solution is (3,-3).
3x+y=6
x-intercept; y=0, x=2 (2,0)
y-intercept; x=0, y=6 (0,6)
2y-x=-9
x-intercept; y=0, x=9 (9,0)
y-intercept; x=0, y=-4.5 (0,-4.5)

What is the area in square millimeters of a rectangle with a width of 8.7 centimeters, and a length of 9.3 centimeters? A. 80,910 mm2 B. 809.1 mm2 C. 8091 mm2 D. 80.91 mm2
Answers
9.3 cetineters equals 93 millileters and 8.7 centimwters equals 87 millileters. So 87 x 93 =8091. Your answer is C
9.2 cm = 92 mm 8.7 cm = 87 mm
92 x 87 = 8004 Answer: 8004 mm
The answer is above :) (btw sry of u spot a mistake)
