Answer:
(-b) is the answer.
Step-by-step explanation:
2(a-b)-(2a-b)
=2a-2b-2a+b (opening the brackets)
= -b
Hope this helps you buddy. Have a nice day^_^.
If you have doubt then you can ask in comments. I will surely answer.
Answer:
A) 5x = y
B) 
Step-by-step explanation:
A is 5x = y because there are 5 pink hearts per the number of boxes (x) bought.
B uses the equation 2x is less than or equal to 100 because the teacher is spending 2 dollars per kid and can spend a maximum of 100.
The graph for this is attached.
Hexagon = 6 sides = 6 x 4 = 24
Octagon = 8 sides = 8
Dodecagons = 12 x 5 = 60
24 + 8 + 60 = 92 IN TOTAL
Answer: She would need 32
Step-by-step explanation:
Answer:
35°
Step-by-step explanation:
We assume that points S, T, U, V all lie on the circle.
Inscribed angle TUV intercepts long arc VST and short arc VUT. The long arc has measure 220°, so the measure of the short arc is 360° -220° = 140°.
Since chords UV and UT are the same length, point U bisects arc VUT. That means the measure of arc VU is 140°/2 = 70°.
Inscribed angle VSU intercepts arc VU, so has half the measure of the arc:
∠VSU = 70°/2
∠VSU = 35°
