Answer:
∠3 is 70°
Step-by-step explanation:
∠1 is 50° since it is across from another 50° angle
and then you use the equation x+25+2x+50=180 to find x
x then equals 35°
you then use the alternate interior angle theorem to say that ∠3 is 2x, or 70°
N=2p
n/2=p
n-5=d
10d+5n+1p=446
subsitute n/2 for p
subsitute n-5 for d
10(n-5)+5n+n/2=446
times 2 both sides
20(n-5)+10n+n=892
expand
20n-100+10n+n=892
31n-100=892
add 100 both sides
31n=992
divide both sides by 31
n=32
subsitute back
n/2=p
32/2=16=p
n-5=d
32-5=d=27
27 dimes
16 pennies
32 nickles
Your answer is
- Slope = -1.000/2.000 = -0.500
- x-intercept = 7/1 = 7.00000
- y-intercept = 7/2 = 3.50000
Step-by-step explanation:
Unknown factor is known as the factor that is not understood and not know(you have no idea what the value is)
