Please help! Final problem for tonight
2 answers:
(4x-6)+(8x+18)=180(adjacent angles are supplementary)
4x-6+8x+18=180
4x+8x-6+18=180
12x+12=180
12x=180-12
12x=168
x168/12
x=14
8x+18=y+3 (corresponding angles are equal)
8×14+18=y+3
130=y+3
-y=3-130
-y=-127
y=127
x=14, y=127
Answer:
x = 14 and y = 127
Step-by-step explanation:
we know that 4x-6 +8x+18 = 180
and 8x+18 = y+3
Let's first solve for x for the first equation.
12x = 180-18+6
x=14
Now solve for y for the second equation.
8(14) +18 = y + 3
y = 8(14) +18 -3
y = 127

Answer:
24 for being able to not have one, 6 for having one of each
Step-by-step explanation:
multiplication
with the option of none
4*2*3=24
without the option of none
3*1*2=6
The first number is 9 and the second number is 10. 10+9=10. 9*2=18 and 10 is 8 less than 18. All the requirements of the numbers are met.
