Answer:
13.7%
Step-by-step explanation:
Percentage decrease = (3.65 - 3.15) / 3.65 * 100% = 13.7%
If the triangles are similar, the base should be 24 inches. The legs on the first triangle are 12 inches. To get 36 inches (the other triangle), we multiply 12 by 3. 12 x 3 = 36. Because you did that to the legs, you must also do it to the base. 8 x 3 = 24. Therefore, the base of the second triangle is 24 inches.
Answer:
y = -8
Step-by-step explanation:
To find the value for y, use the slope formula:
Substitute m = 3 and (-9,y) and (-7,-2).
You need to get the denominator at the same number first. The Lowest common denominator is 6. So multiple 7/3 by 2 and 5/2 by 3 to get 14/6 and 15/6. 15/6 is greater. 15/6 is 5/2, so the answer is 5/2. I hope this helps!
4.5 (4-x)+36=202-2.5(3x+28)
45 (4-x)+360=2020-25(3x+28)
-45x+540=-75x+1320
-45x+540-540=-75x+1320-540
-45x=-75x+780
-45x+75x=-75x+780+75x
30x=780
30x/30= 780/30
x=26 the anser
