Bring them to the same denominator and solve for x
Answer:
∠P = 39º
∠Q=120º
∠R = 21º
Step-by-step explanation:
m∠P+m∠Q+m∠R=180º (sum of ∠s in a triangle)
2x-3+6x-6+x=180º (substitution)
9x-9=180º (algebra)
9x=189º (algebra)
x=21º (algebra) (this is ∠R)
(2x-3)=39º (algebra) (this is ∠P)
6x-6=120º (algebra) (this is ∠Q)
Y = (-1/9).x + 4
The slope m of the line perpendicular to y = (-1/9).x + 4 is equal to 9:
(if the product of 2 slopes = - 1, then the 2 lines are perpendicular)
y = 9x + b, Since it passes by the point (-1,0) , then:
0= 9(-1) + b and b = 9
Final equation:
y = 9x+9
Answer:
24
Step-by-step explanation:
We know that the final answer has to be in inches.
To convert ft = in, multiply given ft. by 12.
1/6 = 1/6 * 12 = 2
1/4 = 0.25 * 12 = 3
1/3 = 0.3 * 12 = 4
2*3*4 = 23 cubic in.
Y=300+40g
Y=5000
5000=300+40g
-300
4700=40g/40
117.5=g
