Answer:
x =106.5
y = 73.5
Step-by-step explanation:
Angle x is 1/2 arc SPQ
x = 1/2(98+115)
x = 1/2(213)
x =106.5
We know that x+y = 180 since this is an inscribed quadrilateral in a circle
x+y=180
106.5 +y =180
Subtract 106.5 from each side
106.5-106.5 +y =180-106.5
y = 73.5
Answer: number (3)
Explain:
Assuming second equation is 6x+8y=44
so first divide 2nd eqation by 2 to make it eqaier
3x+4y=22
sub 6x+4 for y
3x+4(6x+4)=22
3x+24x+16=22
minus 16 both sides
27x=6
divide both sides by 27
x=2/9
sub back
y=6x+4
y=6(2/9)+4
y=12/9+4 (4=36/4)
y=48/9
Answer:
A.) 20h + 8
Step-by-step explanation:
39
sum of 2 digit no. can be
3+9
4+8
5+7
6+6 (which cannot be the ans since interchanging the digits would give 0 difference)
so,
93-39=54
84-48=36
75-57=18
so 93 is the reversed no. and 39 is the original no.
