13-3/2 you need to make a common denominator, so
26/2-3/2 then subtract the numerators, the denominator remains.
23/2 now simplify the fraction
11½ this is because 22/2+1/2=23/2, and 22/2=11, so 11+1/2 or 11½
Teresa counted 2 leaves on May 1st and 9 leaves on September 1st.
The difference in the number of leaves is:
9 - 2 = 7
Hence, the number of leaves has increased by 7 units.
Answer:
3/6x • 4/6x
12/6x
2x
Step-by-step explanation:
you would change both fractions to have the same denominator then simplify if needed
Answer:
m∠3 = 143°
Step-by-step explanation:
m∠1 = 53°
m∠2 = 180 - (90 + 53) = 37°
m∠3 = 180 - 37 = 143°
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (3, 1), hence
y = a(x - 3)² + 1
To find a substitute (- 2, - 4) into the equation
- 4 = a(- 2 - 3)² + 1
- 4 = 25a + 1 ( subtract 1 from both sides )
25a = - 5 ( divide both sides by 25 )
a = - 
= - 
y = - (x - 3)² + 1 ← in vertex form
