Answer:
x=-35
Step-by-step explanation:
136+12x=-4(1-2x)
136+12x=-4+8x
+4 +4
140+12x-12x=8x-12x
140/-4=-4x/-4
x= -35
The picture is difficult to read, but it looks like
∠ADB = 2x²
∠ACB = 10x
These two angles have equal measure, so you have
2x² = 10x
2x(x -5) = 0 . . . . . subtract 10x and factor
x = 0, or x = 5
The measure of arc AB is twice the measure of either inscribed angle, so would be
arc AB = 2×10x
= 2×10×5
= 100 . . . . . degrees
Arc AB is 100°.
I’m pretty sure it would be 1. two less than seven times a number equals thirty-three
A + s = 504
s = a + 54
a + (a + 54) = 504
2a + 54 = 504
2a = 504 - 54
2a = 450
a = 450/2
a = 225 <=== adults
a + s = 504
225 + s = 504
s = 504 - 225
s = 279 <=== students
Answer:
<h3>Encik Arif's mass is 63kg</h3>
Step-by-step explanation:
Let Encik Arif's mass be x
the ratio of Encik Arif's mass to his son's mass is 3:2
That's
<h3>
</h3>
The son's mass is 42, so the ratio of Encik Arif's mass to his son's is
x : 42
That's
<h3>
</h3>
Now equate the two fractions
That's
<h3>
</h3>
Cross multiply
3(42) = 2x
126 = 2x
Divide both sides by 2
We have the final answer as
<h3>x = 63</h3>
Hope this helps you
