Answer:
(1,11)
Step-by-step explanation:
Given expression
y=8x+3
Substitute any values of x
Here, we are substituting x=1
⇒y=8x+3
y= 8+3
y=11
⇒ordered pair=(1,11)
Answer:
C: Either the mean or median; both are 5
Step-by-step explanation:
MEAN: 5+2+4+8+6= 25 = 25/5= MEAN IS 5
MEDIAN: put it in order: 2,4,5,6,8
cross out 2,8,4,6
left over number is 5
So median is 5
Answer:
3x + 15 = 3*10 + 15 = 30 + 15 = 45
<u>3x + 15 = 45</u>
Now,
2x + 25 = 2*10 + 25 = 20 + 25 = 45
<u>2x + 25 = 45</u>
Step-by-step explanation:
3x + 15 + 2x + 25 = 90
or, 5x + 40 = 90
or, 5x = 90 - 40
so, 5x = 50
so, x = 50/5 = 10
Answer:
RT=7
Step-by-step explanation:
RS+ST=RT
5x+x+1=5x+2
6x-5x=2-1
x=1
RT=5x+2
RT=7
I won't bore you with the details, but according to my math the answer should be C. 1/2.
