Answer:
-30
Step-by-step explanation:
let Sarah's number be X
x-15=15x
15x*-5=105
-75x=105
-x=105-75
X=-30

Answer:
Step-by-step explanation: Perimeter is distance around the outside so 8+8+5+5=26 units
Area - I'll get back with you
Begin solving like you normally would. Add 2.25 to both sides and subtract 9x from both sides to try getting all x values on one side. However, you will find that after subtracting 9x from both sides, all x values go away, and you end with -2.25=1.6. This is not true (-2.25 is not 1.6), so the answer is no solution. There is no value of x which satisfies that equation.
11. The negative 8 had to go to the positive 3. You add 8 automatically to get yourself to 0. Once you do that you add three to make them the same to find the distance. The answer is 11.
Answer:
we know that
If two figures are similar, then its corresponding sides are proportional and its corresponding angles are congruent
In this problem
Triangles XZY and VZW are similar
therefore
corresponding angles are congruent
∠XZY≅∠VZW
∠ZXY≅∠ZVW
∠XYZ≅∠VWZ
corresponding sides are proportional
