The opposite angles of a cyclic quadrilateral add up to 180 degrees , so
2x + 3 + 4x + 3 = 180
6x = 180 - 6
6x = 174
x = 29
so m<C = 2(29) + 1 = 59 degrees
Equation: 7(3x-2)=133
Distribute: 21x-14=133
Add like terms: 21x=147
Divide by 21: x=7
Answer:
Last year the cost was $28.
This year the cost is $36.
$36 - $28 = $8
Percent of increase = amount of increase ÷ original amount
$8/$28 = $0.286
$0.286 · 100 = 28.6%
There has been a 28.6% of change in the cost.
Answer:
1) 6
2) 9
3) 80
4) 10
5) 4
6) 4
Step-by-step explanation:
1) 36 / 6 = 6
2) 45 / 5 = 9
3) 10 * 8 = 80
4) 5 * 2 = 10
5) 16 / 4 = 4
6) 12 / 3 = 4
Hope this helped!
Answer:
y=-12/11
Step-by-step explanation:
y-(-12/11)=0(x-(-12/13))
y+12/11=0(x+12/13)
y+12/11=0
y=-12/11
Since the slope equals 0, then the line is horizontal.
