Simplify= 4r+3
Because 8r plus -4r which is 4r and then 3 can’t be simplified so u keep it the same
Then the answer if r=5 is 23
Because the equation looks like 4(5)+3
5 times 4 is 20 plus 3 is 23
There is only one repeating number, so we multiply both sides by
or
.
Now subtract the original number we had to both sides, which is the same as
or
So we have:
Divide 9 to both sides:
Multiply the fraction by 10 to get rid of the decimal in the numerator.
Simplify the fraction by dividing the numerator and denominator by 2:
Answer:
Step-by-step explanation:
B) Small triangle:
height = 20 - 15 = 5
base = 1
height to base = 5 :1
Medium triangle :
height = 60 -30 = 30
base = 2
height to base = 30 :2 = 15 :1
Large triangle:
height = 120 - 60 = 60
base = 4
height to base = 60 : 4 = 15 : 1
c) The ratios are same. This is true because wage and working hours are in direct proportion.
E) Take any two points. (1 , 15) & (2 , 30). Find the slope.
Slope = Change in y ÷ change in x
m = (30-15) ÷ (2 -1) = 15/1 = 15
y -y1 = m(x -x1)
y - 15 = 15(x - 1)
y - 15 = 15x - 15
y = 15x - 15 + 15
y = 15x
Jus go a thru z and you’ll be fine
Is this a question that we can answer? like mathematically? or was this an accident but i do agree with that!
