So in this one, we are DECREASING by 25%, so we say 25% of 820...
25% × 820 =
.25 × 820 = 205
Now since we are decreasing by 25%, we take our answer and subtract it from the original amount, 820.
820 - 205 = 615
820 decreased by 25% is
615.
Cheryl ran the trail twice, so:
252 x 2 = 504
She ran 504 feet. Now convert 504 feet to yards:
3 feet : 1 yard
504 feet : ? yards
Answer: 168 yards
Hope it helped :)
Answer:
3. A=B=70°; C=D=110°
4. A=90°; C=48°
Step-by-step explanation:
Same-side angles of a trapezoid add to 180°.
___
3. (2x) +(x+15) = 180
3x + 15 = 180 . . . . simplify
x +5 = 60 . . . . . . . divide by 3
x = 55
A=B=(x+15)° = (55+15)° = 70°
C=D=2x° = 2·55° = 110°
__
4. You are given the values of one of the angles on each side, so the other can be found by subtraction:
A=180°-D = 90°
C = 180° -132° = 48°
Answer: Y=-1
Explanation: 2y-3=y-4 (add three on both sides)
2y=y-1 (subtract y on both sides)
y=-1
