Answer:
A+*in a house*127^0/0
underfined
Step-by-step explanation:
(13 + x)/(50 - x ) = (2/1)
Cross Multiply
2(50-x) = 1(13 + x)
100 - 2x = 13 + x
add 2x to both sides
100 -2x + 2x = 13 + x + 2x
100 = 13 + 3x
Subtract 13 from both sides
100 - 13 = 13 - 13 + 3x
87 = 3x
divide both sides by 3
29 = x
(13 + 29)/(50-29) = 42/21 = 2 to 1 ratio
Answer:
r = -3
Step-by-step explanation:
Add the like terms: 8r = -24
Isolate r by dividing each side by 8: r = -24/8
Simplify: r = -3

Answer:
49,000 square cm
Step-by-step explanation:
To get the area of the dilated rectangle, we need the dilated dimensions
We simply multiply the scale factor by the dimensions
we have this as;
3.5 * 50 = 175 cm
and
3.5 * 80 = 280 cm
The area of the dilated rectangle is thus;
280 * 175 = 49,000 cm^2
Isolate the p. Note the equal sign. What you do to one side, you do to the other. Multiply 7/6 to both sides
(-2)(7/6) = (6/7)(7/6)p
p = (-2)(7/6)
Multiply -2 and 7, then divide by 6
p = (-2 x 7)/6
p = -14/6
Divide
p = ~-2.33 (rounded)
-2.33 is your answer
