Answer: x=1 y=3....do you need to show your work?
32/10 as a mixed number is 3 2/10
2x+y=25
3x-y=20
solve by adding these two equations together
2x+3x=5x
y-y=0
25+20=45
you get left with
5x=45
divide both sides by 5
x=9
then plug x=9 into one of the 1st equations to solve for y
2(9)+y=25
18+y=25
subtract
y=7
so your numbers are 9 and 7
Circle A is missing, so i have attached it.
Answer:
∠XYZ = 35°
Step-by-step explanation:
We want to find the angle ∠XYZ in the image attached.
To solve that, we will use the formula in the theorem for angle formed by secants or tangents. Thus;
∠XYZ = ½(arc WZ - arc XZ)
From the image, arc WZ = 175° and arc XZ = 105°
Thus;
∠XYZ = ½(175 - 105)
∠XYZ = ½(70)
∠XYZ = 35°
