Answer:
A) x = 10-/3, y = 20
Step-by-step explanation:
To answer this item, we let x be the number of hours per month that Mrs. Gleason should work. The total budget is equal to sum of the amount acquired by Mr. Gleason and Mrs. Gleason. The equation that would express this is,
4,500 = 900(4) + 9x
The value of x from the equation is 100. <em>Thus, Mrs. Gleason should work for 100 hours per month. </em>
Answer:
Step-by-step explanation:
c) ∠BAC
d) ∠CAB
Answer:
X¹= -2 + 2√33
X²= -2 - 2√33
Step-by-step explanation:
X × (X+2) = 32
X² + 2X = 32
X² + 2X - 32= 0
Δ=132
X= -2 ± 2√33
X¹= -2 + 2√33
X²= -2 - 2√33
(You can change the 2√33 to 11,5 if you want to)
To find the greatest common factor or GCF, first factor 12 and 30 and find factors that are both present in both numbers.
12 = 2*2*3
30 = 2*3*5
Both have a common factor of 2*3 which is 6, and since it is present in both numbers and is the greatest, it is the GCF.
The GCF of 12 and 30 is 6. Hope this helps.
