Answer:
B = 3
Step-by-step explanation:
3x + 15 = 4x + 12
= 15-12=4x-3x
= 3 = x
X = 3
<span>2/5(10x - 10y) - 3/4(12x - 24y)
=4x - 4y - 9x + 18y
= -5x + 14y
answer is </span><span>A) -5x + 14y </span>
Answer:
A= 65 C= 65 and D= 115
Step-by-step explanation:
given a parallelogram .
interior angles sum is 360 degree.
sum of adjacent angles is 180degree.
opposite angles are congruent (B=D).
A + B + C + D = 360
(A + D) + C + 115 = 360 since A and D are adjacent angles .
180 + 115 + C = 360
295 + C = 360
C = 360 - 295
C = 65
D = 115
A = 65
a+b+c+d=360
65 + 65 + 115 + 115 = 360
130 + 230 = 360
360 = 360
Answer:
1,225
Step-by-step explanation:
you mutuply the sides
12 year old runs = 100 yards
By proportionality, 6 year old will run = 100/2 = 50 yard
In total, they ran = 100 + 50 = 150 Yard
In short, Your Answer would be 150 Yards
Hope this helps!
