Answer:
Step-by-step explanation:
Since 2 triangle are similar
So sides of both triangle are equal
So 72/X=12/10
X= 72x10/12
=60
X=60 is the answer
Answer:
x = 2.67
Move variables to the right and constants to the left, Then divide and you get the answer.
Step-by-step explanation:
-1.3+4.6x=0.3+4x (given)
-1.3x + 0.6x =0.3 (subtraction property of equality)
0.6x = 1.6 (addition property of equality)
x = 2.66666666667 (division property of equality)
2.66666666667 = 2.67 (rounding to the nearest tenth)
Step-by-step explanation:
f(x) = 3 - 4x
f(1+a)= 3-4(1+a)
=3-4+4a
=4a-1
Answer:
y=-5
Step-by-step explanation:
every point on a horizontal line has the same y-value. use y-value of the point to find the horizontal-line equation.
