Hey there!!
The given equation :
... 3x + 3 ( 5x - 18 ) = 108
... 3x + 15x - 54 = 108
... 18x - 54 = 108
... 18 x = 162
This is equivalent to the above question.
... The solution would be 162 / 18 = 9
Hope my answer helps!!
Answer: w =1 L=6
Step-by-step explanation:
What is Perimeter = 2 L + 2W
2L + 2B =14
L = 2W + 4
2(2W + 4) + 2W = 14
4W +8 +2W =14
6W=14-8
W=1
L=2W +4= 6
<span>Julia is X+5
</span><span>x+x+5=31
</span>
Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
Answer:
m∠C = 66°
Step-by-step explanation:
Since AB = BD, it means this triangle is an Isosceles triangle and as such;
∠BAD = ∠BDA = 24°
Thus, since sum of angles in a triangle is 180,then;
∠ABD = 180 - (24 + 24)
∠ABD = 180 - 48
∠ABD = 132°
We are told that BC = BD.
Thus, ∆BDC is an Isosceles triangle whereby ∠BCD = ∠BDC
Now, in triangles, we know that an exterior angle is equal to the sum of two opposite interior angles.
Thus;
132 = ∠BCD + ∠BDC
Since ∠BCD = ∠BDC, then
∠BCD = ∠BDC = 132/2
∠BCD = ∠BDC = 66°
Answer:
140y
Step-by-step explanation:
35 times a number times -4 is 35×y×(-4) which is -140y
